Panipuri Inside a Spaceship
—Vidya Pradhan
Astronauts are people who travel into space to explore and study things beyond Earth. They live and work on spaceships to learn more about the universe.
Imagine you are an astronaut in a spaceship. What are the different things you would see from your spaceship? Draw or paste in pictures of any four things.
Chikki is quite fussy about the food she eats. Then, she learns something interesting that makes her think about food in a completely different way. What does she learn? Let’s read the story to find out.
Let’s Read
‘Dinner time!’ called Daddy.
Chikki and Ninu, who were playing outside, came running in. Daddy was already at the table. ‘What are we having?’ asked Ninu. ‘Mooli parathas,’ said Mummy. ‘And raita.’ Chikki wrinkled her nose. ‘Not again!’ she complained.
‘Chikki, don’t you want to be an astronaut?’ asked Mummy. ‘Yes,’ responded Chikki.
Talking Book
Mummy was a scientist and Daddy had been a fighter pilot. Chikki wanted to study science and fly higher than Daddy—she wanted to be an astronaut.
‘Well,’ said Mummy, ‘If you eat your parathas, I’ll make astronaut food for you tomorrow.’
‘Okay!’ said Chikki happily and wolfed down her paratha.
Think and Tell
Why did Chikki agree to eat her paratha happily?
ControlCopy
wrinkled: pulled up the nose in a way that it made lines wolfed down: ate quickly and eagerly
The next day, Chikki and Ninu came back from school for lunch. They were eager to see what Mummy had made. Instead, they saw a tube on their plates. ‘Toothpaste!’ cried Ninu. ‘Is that what astronauts eat?’
Think and Tell
What did Ninu think Mummy was serving them for lunch when they came back from school?
‘Not toothpaste,’ Mummy smiled. ‘I mashed up rice and dal and put it in the tube. You can squeeze it into your mouth.’
‘Why can’t we have rice and dal on the plate instead?’ asked Chikki. Daddy had some on his plate. And it suddenly looked delicious.
Daddy pointed to his food. ‘See how it stays on my plate? In space, it would float away.’
Chikki and Ninu imagined bits of rice floating in the air. ‘Nom-nom-nom,’ said Ninu as he pretended to catch the grains. ‘Watch out, rice, I’m coming for you!’
‘It looks like fun, but it would take very long to finish eating. And bits could end up in the spaceship’s engines and make a mess,’ said Daddy.
‘But why does food float in space?’ asked Chikki. ‘It doesn’t float down here!’
‘On Earth, we have gravity. It keeps not just food but all of us from floating into space,’ explained Daddy. That is why when we throw a ball up into the air, it falls back down.’
Mummy added, ‘Far from Earth, there is almost no gravity. So, astronauts and other things in space weigh almost nothing. They float!’
‘And food out there has to be easy to eat and not float away every time someone tries to have lunch!’ said Daddy.
Think and Tell
What does Daddy say Earth has that space does not have?
mashed up: crushed and mixed into a soft, smooth mixture
spaceship: a vehicle that travels in space
Did You Know?
Gravity is what makes you feel your weight. On the Moon, gravity is weaker, so you would weigh less than you weigh on Earth.
gravity: the force that pulls things down to the ground and keeps them from floating away
Chikki looked at the tube on her plate. ‘So this is what astronauts eat?’ She was disappointed.
Mummy smiled. ‘When they first started going into space, astronauts ate vegetable and fruit pastes from tubes. That was not very tasty. So they complained, like you!’ she said.
‘So scientists tried to come up with options that looked and tasted more like regular food. Today, astronauts get canned food, nuts, protein bars … anything they can eat in a single bite without leaving crumbs. So Indian astronauts take paneer curry and other tasty dishes.
‘And now,’ said Mummy, ‘you have to try these gobi parathas.’ ‘Oh no!’ said Chikki. ‘When I become an astronaut, I’m going to take panipuri along!’
New dishes we read about:
Think and Tell
What did the astronauts complain about when they first started going into space?
Mooli paratha: whole wheat flatbreads with a spiced radish filling
Raita: a side dish that is made of yoghurt
Panipuri: a popular Indian street food with crispy, hollow, fried dough balls stuffed with boiled potatoes or steamed moong sprouts together with spicy tangy water
Gobi paratha: whole wheat flatbreads with a spiced cauliflower filling
canned: food that is sealed in a metal can to stay fresh for a long time

crumbs: tiny pieces that break off from food

Henry, a chameleon, is the latest pet in Grandfather’s private zoo. What would it be like to have a chameleon as a pet? Are chameleons naughty or calm? Let’s read to find out.
—Ruskin Bond
Henry is our pet chameleon. Chameleons are no ordinary reptiles. A chameleon’s tongue is as long as its body. Its limbs are long and slender, and its fingers and toes look like a parrot’s claws. On its head may be any of several ornaments—Henry had a rigid crest that looked like a fireman’s helmet.
Talking Book
Henry’s eyes were his most remarkable feature. He could move one eye without disturbing the other. Each eyeball, bulging out of his head, wobbled up and down, backward and forward.
One look into Henry’s frightful gaze was often enough to scare people into believing that chameleons are dangerous and poisonous reptiles.
Grandfather was visiting a friend in northern India when he came upon a noisy scene at the garden gate. Men were shouting, hurling stones and brandishing sticks. The cause of the uproar was a chameleon. The residents of the area had risen in arms. Grandfather was just in time to save the chameleon from certain death—he brought the little reptile home.
Think and Tell
When did the Grandfather adopt Henry as a pet?
slender: thin and graceful ornaments: decorative features rigid: stiff crest: raised part on top of an animal’s head feature: a part of something that makes it special wobbled: moved in a manner where you do not have much control
hurling: throwing something forcefully brandishing: waving something in a harmful manner
uproar: situation where people yell and create a lot of noise because they are upset had risen in arms: were ready to attack
ControlCopy
I would tickle him gently in the ribs with my finger. This always threw him into a great rage. He would blow himself up to an enormous size, his lungs filling his body with air, while his colour changed from green to red. He would sit up on his hind legs, swaying from side to side, hoping to overawe me. Opening his mouth very wide, he would let out an angry hiss. But his threatening display went no further. He did not bite.
He was a harmless fellow. If I put my finger in his mouth, even during his wildest moments, he would simply wait for me to take it out again. I suppose he could bite. His rigid jaws carried a number of finely pointed teeth. But Henry seemed convinced that his teeth were there for the sole purpose of chewing food, not fingers.
Think and Tell
What are some ways that the author would play with Henry?
Although Henry didn’t cause any trouble in our house, he did create somewhat of a riot in the nursery down the road. It started out quite innocently.
When the papayas in our orchard were ripe, Grandmother sent a basketful to her friend Mrs Ghosh, who was the principal of the nursery school. While the basket sat waiting, Henry went searching for beetles and slipped in among the papayas, unnoticed. The gardener dutifully carried the basket to the school and left it in Mrs Ghosh’s office. When Mrs Ghosh returned after making her rounds, she began admiring and examining the papayas. Out popped Henry.
rage: anger
enormous: very large overawe: to scare someone hiss: a sharp blowing sound, often made by reptiles riot: a situation of confusion dutifully: in a manner that shows one is responsible
ControlCopy
Mrs Ghosh screamed. Henry squinted up at her, both eyes revolving furiously. Mrs Ghosh screamed again. Henry’s colour changed from green to yellow to red. His mouth opened as though he, too, would like to scream. An assistant teacher rushed in, took one look at the chameleon, and joined in the shrieking. Henry was terrified. He fled from the office, running down the corridor and into one of the classrooms. There he climbed up a desk while children ran in all directions—some to get away from Henry, some to catch him. Henry finally made his exit through a window and disappeared in the garden.
Grandfather and I didn’t think Henry would find his way back to us, because the school was three blocks away. But a few days later, I found him sunning himself on the garden wall. Although he looked none the worse for his adventure, he never went abroad again. Henry spent the rest of his days in the garden, where he kept the insect population well within bounds.
squinted: looked with eyes partly closed revolving: spinning shrieking: making loud noises abroad: outside of one’s usual surroundings well within bounds: (here) kept the insect numbers down

13 . Manu Mixes Clay and Sunshine
—Bulbul Sharma
If you were given a lump of clay, what would you make with it? Why? I would make Get Set
ControlCopy
Manu’s father and grandfather are skilled potters, and Manu is learning the craft. Let’s read this lively story to learn about the simple joys and the hardships of a potter’s life, from gathering clay and making pots to selling them in the markets.
BHARAT
Manu was still in bed. The sun was already up. He should have risen earlier, but last night was firing day, a busy time for his family of potters.
The rainy season had ended, and the sky was clear. Today, Manu would dig for clay with his grandfather, Dada, near the river. Later, Baba, his father, would take him to the city to sell pots at the market.
Talking Book
Manu had learned the basics of pottery from a young age. As a baby, he played with lumps of clay. At three, he learned to shape it into balls. Every afternoon, he and his sister Sushma sat under a peepal tree, rolling tiny clay balls.
Did You Know?
Pottery is the art of making items like pots, bowls and vases from clay. India is well known for this beautiful craft. There is the colourful and detailed Khurja Pottery of Uttar Pradesh and the bright blue Jaipur Blue Pottery of Rajasthan. There are also the tribal designs of Manipuri Pottery and the black pottery with silver designs of Nizamabad.
Think and Tell
Where would Manu go with his grandfather?
skilled: very good at doing something firing: baking clay pots in a very hot oven to make them hard and strong
potters: people who make pots, bowls, and other items from clay basics: simple yet important skills and knowledge
Manu loved the cool touch of clay in summer, and making toys with Ma in winter. Their house was filled with earthenware pots, teacups, flowerpots and bowls. During festivals, people bought Ma’s little Ganesha and Lakshmi statues.
Before Diwali, Manu and Sushma made small diyas. His friends often asked for extras, and Ma made a few more for him to give away. ‘Potters have special hands that turn clay into wonderful things,’ Ma said.
That morning, Dada and Manu set out for the river. Manu eagerly ran towards a banyan tree where they dug up the clay.
After filling their sacks, they returned home. The next day, Manu helped Baba break the dried clay into small pieces, sieve it, and knead it with water. He and Sushma loved jumping on the wet clay which made a funny sound. Baba and Dada shaped the clay into pots on the wheel, as if by magic.
Manu’s pots weren’t as perfect as his father’s or grandfather’s, but he enjoyed making toy animals. He had secretly made an owl for Sushma and a toy car for his brother. Only Baba knew about these gifts as they were in the kiln.
Think and Tell
What are the different steps Manu and his family followed to make the pots?
earthenware: pottery made from baked clay sieve: to separate larger pieces from smaller pieces by using a tool with small holes
Think and Tell
Which ‘wonderful things’ did Ma make?
knead: to mix and press a soft material like clay or dough with your hands until it is smooth kiln: a special oven used for baking and hardening clay items
Once the kiln cooled, Baba would take the pots to the market, and this time, Manu would go too! He was excited about the trip to the big city.
On market day, they loaded pots onto donkeys and headed to the city. The journey was long, but Manu enjoyed seeing new places. In the city, they sold all their pots and toys.
Baba bought new things for the family with the money they earned.
Manu saved some money and wanted to buy something for Baba. He found an old man selling umbrellas. Manu helped the man with some work and got an umbrella in return. He hid it carefully, so that he could surprise Baba.
They returned home at dawn the next day.
Manu excitedly shared his experiences with Ma and Sushma. They made tea in a big clay pot and watched the sky turn pink and orange, ready for another day of pottery.

The Paralympic Games is a big sports event where athletes with disabilities compete in different sports. The event happens every four years, just like the Olympics. Athletes from all over the world come to show their skills and win medals for their countries. One such athlete is Sumit Antil from India, a champion in javelin throwing—a sport in which a long spear, called a javelin, is thrown as far as possible. Let’s hear from him as he shares his inspiring story with a group of Grade 4 students.
Let’s Read
The Grade 4 students have taken their seats in the school hall. The air is buzzing with excitement as the students look forward to talking to their guest.
Their teacher, Ms Radhika, takes the stage. She introduces India’s paralympian and javelin thrower, Sumit Antil and the students clap loudly.
Talking Book
Ms Radhika: Today, we have Sumit Antil, world champion javelin thrower, as our guest! He has made a name for himself in para-athletics and has represented India in various international competitions. His dedication and hard work have earned him recognition and accolades, including medals in important events like the Paralympics and World Para Athletics Championships. Students, are you ready with your questions? (pauses for a moment) Riya, please ask your question.
Riya: Hello, Sumit Sir! Can you tell us about your early life?
Sumit Antil: Sure, Riya. I grew up in Khewra village in Haryana and like many children there, I dreamed of becoming a wrestler. I was a huge fan of Yogeshwar Dutt. So, I spent my days practising because it was my dream to be a champion. Life, however, had another plan for me.
Aarav: Sir, we know that your accident in 2015 changed your life. Can you tell us about that time?
Did You Know?
Yogeshwar Dutt is the 3rd ever Indian wrestler to have won an Olympic medal for India. He has been honoured with the Rajiv Gandhi Khel Ratna award (2012) and Padma Shri award (2013).
Sumit Antil: I was returning home from a tuition class one evening and a speeding truck hit my motorbike. The accident was quite serious, and doctors had to amputate my left leg. I was 17, and it was a really tough time. My dream of becoming a wrestler had vanished overnight. All my friends were deciding what they wanted to do with their lives and I felt sad and lost.
Para-athletics: athletics for people who are disabled in some way recognition: fame and acceptance accolades: honour and awards
Think and Tell
What incident caused Sumit’s dream of becoming a wrestler to vanish overnight?
amputate: to remove a certain body part through surgery vanished: disappeared suddenly

Arjun: I am really sorry to hear that, sir. How did you move forward, and what made you learn javelin throwing instead?
Sumit Antil: I met my coach Naval Singh by chance and he introduced me to javelin throwing. That day, I discovered a new passion, and that helped me pull myself out of those dark times. I moved to New Delhi to train seriously, and I dedicated myself to the sport. I missed my family and the comforts of home, but I knew I could not give up on my newly found dream!
Fatima: Can you tell us about your experience at the Tokyo Paralympic Games?
Sumit Antil: I qualified for the Tokyo Paralympic Games in 2020, and competing in the men’s F64 javelin throw event was an unforgettable experience. I broke the world record three times in the same competition! My first throw was 66.95 metres, which was a new record. My second throw was even further, and finally, my throw of 68.55 metres won me a gold medal.
ControlCopy
Iqbal: What would you say is the secret to your success?
Sumit Antil: I believe it is understanding my body and its needs. I chose a prosthetic foot instead of a blade, which many other athletes used. I felt the blade was pushing me backward when I threw the javelin. By understanding my body and making the right choices, I was able to give my best.
Neha: What advice would you give someone who wants to take up javelin throwing or any other sport?
Sumit Antil: Javelin throwing requires skill and technique, which only comes with practice.
passion: a strong feeling of love for or interest in something
prosthetic: an artificial body part that is made to replace one that has been lost technique: a special way of doing something
Did You Know?
Devendra Jhajhari, who was also a javelin thrower, won his first gold in 2004 and his second in 2016, making him the first Indian paralympian to win two gold medals.
Never give up, stay dedicated. Also be ready to train in various conditions. I knew Tokyo is humid, so I trained in humid conditions to get used to it.
Aarav: How did it feel when you returned to India after your victory?
Think and Tell
How did Sumit prepare for the Tokyo Paralympic Games in 2020?
Sumit Antil: It was overwhelming! Thousands of people greeted me at the airport. My family, especially my mother, was very proud and emotional. It was a moment of great joy and pride.
Meera: What are your future goals, Sir?
Sumit Antil: I am determined to win gold medals at the 2024 Paris Paralympics and possibly the 2028 Los Angeles Paralympics. I want to push the limits of my abilities, keep improving my throw distance, and inspire others to do the same.
Children: Thank you for sharing your story, Sumit Sir! You are a true inspiration to all of us.

A verb form that shows the time of an action is called its tense.
Let us look at how to use the verb forms in the present continuous tense.
Doer I
He, She, It We, You, They
Rule am + verb + ing is + verb + ing are + verb + ing
Example I am training for the race at the moment. Sumit is answering their questions now. The students are talking to the guest.
We use is, are, or am (the verbs ‘to be’) to make negative sentences and to ask questions in the present continuous tense.
Type Negative Sentence Question
Rule Use ‘not’ between the verb ‘to be’ and the main verb + ing. You can use contractions like isn’t or aren’t.
Examples I am not training for the race. Sumit isn’t answering their questions. They aren’t asking him more questions.
ControlCopy
Move the verb ‘to be’ to the front of the sentence. Add a question mark at the end.
Am I training for the race?
Is Sumit answering their questions? Are they asking him more questions?
1. Use the correct verb forms for the present continuous tense.
a Who is going to accept the award? Oh wait, the coach (go) up.
b Why the captain (not go)?
c He (represent) India in the Olympics at the moment.
d I see the members of the team (look) very pleased with themselves. Look, those two team members (hug) each other.
e Everyone (cheer) with them.
2. Fill in the blanks using the correct option for the given tense.
a Simple present: Murli (swims/is swimming) very well.
b Present continuous: Murli (prepares/is preparing) for the paralympics. swims
c Present continuous: His friends (record/are recording) his times.
d Present continuous: The coaches (watch/are watching) each player closely.
e Simple present: I am sure the whole country (be) proud of Murli.
Past Continuous Tense
We use the past continuous tense to talk about actions that were happening in the past. It’s like peeking into a moment from the past when something was busy happening. Let’s look at verb forms for the past continuous.
One doer (Self and others)
One doer (you) and more than one doer was + verb + ing were + verb + ing
For example: I was returning home from a tuition class when a truck came by. Sumit was sharing his story on the stage.
For example: All my friends were deciding what they wanted to do. You were entering the Olympic stadium this time last year!
The rules for past continuous tense in negative sentences and questions are similar to those of the present continuous tense.

Once upon a time, in a small village named Greenfield, there lived a young boy named Ravi who loved building things. He dreamed of inventing something to help his village.
One sunny morning, Ravi noticed how hard it was for people to fetch water from the well. Determined to find a solution, he started sketching designs in his notebook but he lacked the necessary materials.
Ravi went to his teacher, Mrs Kapoor, who encouraged him and provided some materials from the school’s science lab. She also suggested he should present his idea to the village council. Impressed by his determination, the council provided additional materials and access to the community workshop.
Ravi worked tirelessly, learning from each mistake. After weeks of hard work, he completed his ‘Water Helper,’ a cart with big wheels and a pulley system that could carry six pots of water at once.
Thanks to Ravi’s invention, fetching water became much easier for everyone in Greenfield. Ravi felt proud and happy to have made a difference.

15 . The Baker’s Dozen
Get Set
Name five things you would get at the following places.
ControlCopy
Van Amsterdam was a very popular baker, but something happened and he lost all his customers. How did he get his business running again? Let’s find out.
In the Dutch colonial town later known as Albany, New York, there lived a baker, Van Amsterdam, who was as honest as he could be. Each morning, he checked and balanced his scales, and he took great care to give his customers exactly what they paid for—not more and not less.
Van Amsterdam’s shop was always busy, because people trusted him, and because he was a good baker as well. And never was the shop busier than in the days leading up to December 6, Saint Nicholas Day.
At that time of year, people flocked to the baker’s shop to buy his fine Saint Nicholas cookies. Made of gingerbread, iced in red and white, they looked just like Saint Nicholas as the Dutch know him—tall and thin, with a high, red bishop’s cap, and a long, red bishop’s cloak.
One Saint Nicholas Day morning, the baker was just ready for business, when the door of his shop flew open. In walked an old woman, wrapped in a long black shawl.
‘I have come for a dozen of your Saint Nicholas cookies.’
Taking a tray, Van Amsterdam counted out twelve cookies. He started to wrap them, but the woman reached out and stopped him.
‘I asked for a dozen. You have given me only twelve.’
‘Madam,’ said the baker, ‘everyone knows that a dozen is twelve.’
Dutch: belonging to the Netherlands colonial: (here) set up as a colony of a different country
Saint Nicholas Day: a day that is celebrated to honour a Christian saint, named Nicholas
Think and Tell
Talking Book
What made Van Amsterdam so popular with his customers?
flocked: came together in a large group bishop: a high-ranking priest of the church cloak: a long piece of cloth that is worn over one’s clothes dozen: twelve
ControlCopy
‘But I say a dozen is thirteen,’ said the woman. ‘Give me one more.’
Van Amsterdam was not a man to bear foolishness. ‘Madam, my customers get exactly what they pay for—not more and not less.’
‘Then you may keep the cookies.’
The woman turned to go, but stopped at the door.
‘Van Amsterdam! However honest you may be, your heart is small and your fist is tight. Fall again, mount again, learn how to count again!’
Then she was gone.
From that day, everything went wrong in Van Amsterdam’s bakery. His bread rose too high or not at all. His pies were sour or too sweet. His cakes crumbled or were chewy. His cookies were burnt or doughy.
Think and Tell
‘Van Amsterdam! However honest you may be, your heart is small and your fist is tight.’ Do you agree with the woman? Why/Why not?
ControlCopy
His customers soon noticed the difference. Before long, most of them were going to other bakers.
‘That old woman has bewitched me,’ said the baker to himself. ‘Is this how my honesty is rewarded?’
A year passed. The baker grew poorer and poorer. Since he sold little, he baked little, and his shelves were nearly bare. His last few customers slipped away.
Finally, on the day before Saint Nicholas Day, not one customer came to Van Amsterdam’s shop. At day’s end, the baker sat alone, staring at his unsold Saint Nicholas cookies.
‘I wish Saint Nicholas could help me now,’ he said. Then, he closed his shop and went sadly to bed.
That night, the baker had a dream. He was a boy again, one in a crowd of happy children. And there in the midst of them was Saint Nicholas himself.
your fist is tight: a phrase that means a person does not give generously; a miser mount: get back up doughy: not fully baked customers: people who buy something
Think and Tell
How did Van Amsterdam feel when he lost all his customers?
bewitched: put a magic spell on bare: empty slipped away: (here) slowly stopped coming midst: in the middle
The bishop’s white horse stood beside him, its baskets filled with gifts. Nicholas pulled out one gift after another, and handed them to the children. But Van Amsterdam noticed something strange. No matter how many presents Nicholas passed out, there were always more to give. In fact, the more he took from the baskets, the more they seemed to hold.
Then Nicholas handed a gift to Van Amsterdam. It was one of the baker’s own Saint Nicholas cookies! Van Amsterdam looked up to thank him, but it was no longer Saint Nicholas standing there.
Smiling down at him was the old woman with the long black shawl.
Van Amsterdam awoke with a start. Moonlight shone through the half‑closed shutters as he lay there, thinking.
‘I always give my customers exactly what they pay for,’ he said, ‘not more and not less. But why not give more?’
The next morning, Saint Nicholas Day, the baker rose early. He mixed his gingerbread dough and rolled it out. He moulded the shapes and baked them. He iced them in red and white to look just like Saint Nicholas. And the cookies were as fine as any he had made.
Van Amsterdam had just finished, when the door flew open. In walked the old woman with the long black shawl.
‘I have come for a dozen of your Saint Nicholas cookies.’
In great excitement, Van Amsterdam counted out twelve cookies—and one more.
‘In this shop,’ he said, ‘from now on, a dozen is thirteen.’
Think and Tell
What did Van Amsterdam realise? Was it important?
ControlCopy
with a start: suddenly shutters: covers on windows
moulded: formed
‘You have learned to count well,’ said the woman. ‘You will surely be rewarded.’ She paid for the cookies and started out. But as the door swung shut, the baker’s eyes seemed to play a trick on him. He thought he glimpsed the tail end of a long red cloak.
As the old woman foretold, Van Amsterdam was rewarded. When people heard he counted thirteen as a dozen, he had more customers than ever.
In fact, Van Amsterdam grew so wealthy that the other bakers in town began doing the same. From there, the practice spread to other towns, and at last through all the American colonies. And this, they say, is how thirteen became a ‘baker’s dozen’—a custom common for over a century, and alive in some places to this day.
Did You Know?
The concept of bakers giving thirteen pieces instead of twelve originated in England because of a law that one of their kings had passed.
Think and Tell
Did giving thirteen cookies for the price of twelve work for Van Amsterdam?
glimpsed: caught a quick look foretold: said something was going to happen before it happened colonies: countries or areas controlled politically by a more powerful country (in this case England, Scotland, and later Great Britain) custom: an established way of doing things century: a hundred years

Subject-Verb Agreement Remember!
In a sentence, the subject is who or what the sentence is about. The subject is mostly the doer or the thing about which the information is given. The verb is the action which takes place.
In a sentence, a verb should match with or agree with the subject in number (singular or plural). This is called subject-verb agreement.
If the subject is singular, the verb will also be singular, that is, the verb form will be verb + s/es.
If the subject is plural, the verb will also be plural.
Subject Type Verb Form
One person, animal or thing singular
More than one person, animal or thing plural
An uncountable noun singular
A collective noun singular
Subjects joined with and plural
Subjects joined with or, either/or, neither/nor singular or plural depending on the noun closest to the verb
Singular pronouns like each, nobody, everyone, every singular
Plural pronouns like several, many, few, a few, both plural
When there or here is used, the subject comes after the verb singular or plural
When using ‘some’ singular or plural

In the mountains of Persia (now Iran), there is an ancient art of hand-weaving carpets that is slowly disappearing. For centuries, skilled weavers have carefully created stunning carpets using wool or silk dyed with natural pigments of plants and minerals. They use patterns that tell stories of their culture, beliefs, and history and symbols representing prosperity, happiness, or protection. These weavers often work from home and each carpet is a masterpiece, often taking months or even years to complete. Some carpets contain more than a million hand-tied knots. However, as machines take over and cheaper, mass-produced carpets flood the market, this beautiful tradition is fading away. If fewer people learn the art and if it isn’t preserved, a piece of history will be lost forever. Saving this art, means keeping a connection to the past alive. The intricate stories woven into every carpet must remain a part of the world’s cultural heritage.

Usain Bolt, the fastest runner in the world, didn’t have an easy journey. Even though he was fast, he faced problems like having a curved spine and a hamstring injury that almost stopped him from running. He practised every day, running up and down hills and doing exercises to get stronger. Even when things were tough, he kept trying and stayed focussed on his dream. His hard work helped him win eight Olympic gold medals and break many world records before he retired from competitive sport in 2017. Usain Bolt’s story teaches us that, no matter how many obstacles we face, staying focussed and working hard can help us achieve our goals and make our dreams come true.

Riya and Pooja went to the market to buy some sweets. The shopkeeper took a paper cutout and folded it into a box. Riya wondered how a cutout turned into a box. Pooja explained that the cutout was the net of the box. A three-dimensional shape can be made by folding two-dimensional (2-D) shapes. Such shapes, which are used to make a 3-D shape, are called nets.
The net of the sweet box looked like this. Below are some more nets of a cuboid.
Similar to a cuboid, we have the nets of a cube. Unfolding a cube box along its edges gives the net shown below.

Patterns Around Us
Seema and her Mother are buying garments together.
Seema: Mom! Look at that scarf! The design on it is unique!
Mother: Yes, Seema. This is a Shibori design which is a traditional Japanese dyeing technique.
ControlCopy
Seema: The black, white, and brown lines create a repeating pattern across the entire cloth. It is a very interesting pattern.
Mother: Yes, a very interesting pattern!
Extending and Creating Patterns
Seema and her Mother are discussing the pattern on the cloth above. But what does a “pattern” mean in geometry?
In geometry, a pattern refers to the arrangement of shapes or objects in a regular and repeating manner. These patterns can be based on various factors such as size, shape, colour or direction.
Repeating Patterns
In the figure below, the green square and the red square are arranged in an order and are repeating.
What kind of pattern do you see in the print on the cloth? Think and Tell
Did You Know?
Pine cones have a spiral pattern.
In this case the repeating unit is
Patterns like these, in which a certain unit keeps repeating over and over again in an order, are called repeating patterns.
The craftsman in the image is making a pattern with a wooden block on cloth. The wooden block is dipped in different colours to form different patterns. This art is called block printing.
Example 1: Complete the following pattern:
Rotating Patterns
A rotating pattern occurs when shapes or objects turn around a centre point and repeat.
ControlCopy
Terms that make up a pattern can look different or the same after you rotate them.
Growing and Reducing Patterns
Notice how the pattern in the figure grows: it starts with 2 squares, then becomes 4 squares, then 6 squares and finally 8 squares. These are called growing patterns.
Rule: The number of squares is increasing by 2 each time.
Opposite to growing patterns, in reducing patterns, the units reduce through the steps.
Rule: The number of circles is reduced by 4 each time. 12 8 4 2 4 6 8
Example 2: Complete the following pattern for one more step. Also, identify the type of pattern.
Notice that the stars are increasing with each steps. Therefore, this is a growing pattern.
Did You Know?
Euclid, a Greek mathematician, studied shapes and discovered patterns in their sides and angles. This helped us classify shapes and understand their properties better.
Example 3: Complete the following pattern and recognise the type of pattern.
The number of triangles decreases as the steps increase. This forms a reducing pattern: starting with 5 triangles, then 4, then 3, losing one triangle at each step.

Tiling Patterns and Tessellations
Yes, if you look closely, the brick structure that we see when walls are built is actually a pattern.
Layers 3 and 4 are basically a repeat of layers 1 and 2.
Also, notice that once all these layers are attached to one another, there is no gap in the final pattern. Also, there are no overlaps of bricks anywhere.
Did You Know?
A honeycomb structure is also an example of tessellation!
Hexagonal shapes are arranged together to form the honeycomb.
Layer 1
Layer 2
Layer 3
Layer 4
Such patterns are created by fitting together identical shapes (tiles) without any gaps or overlaps to cover a flat surface, such as a wall, and are called tessellations.
The following are some tessellating and non-tessellating patterns.
Have you ever looked around at the walls and floors? Do you observe any pattern in them? A tessellating
Tangrams
Look at the collection of shapes in the square. Interestingly, the individual shapes do not necessarily repeat, like in a pattern. However, they fit together in a larger square.

We can say: 7 5 20 23 5 12 12 19 15 15 14
This way of turning information or messages into special secret codes or hidden patterns is called coding.
Now what if our friend—who knows the above code—sends us the following message?
How will we understand this?
We refer to the same table above.

Raj: Yes. Butterflies are very special. I like them. Their wings on both sides have the same size and a similar pattern! Real Life Connect Symmetry
Raj and Riya observe that the wings of a butterfly have similar patterns. The two wings look very similar! The butterfly is symmetrical.
Let us learn about symmetrical and non-symmetrical figures.
When a shape can be folded so that one half of it fits exactly on the other half along the fold line, the shape is said to be symmetrical.
The fold line is called the line of symmetry.
Now, let us try to create a symmetrical figure using a sheet of paper.

Line of symmetry Line of symmetry
Symmetry exists all around us. The following shapes are also symmetrical:
In the figures given below, the line of symmetry does not divide the shapes into two identical halves. Therefore, these figures are not symmetrical and so they are called asymmetrical.
We saw previously that the line of symmetry divides the butterfly into two identical halves. Are there different types of lines of symmetry? Let us see!
Vertical symmetry
Vertical symmetry means that if you divide an object or shape down the middle, the left side will look exactly like the right side. This dividing line is called the vertical line of symmetry.
Horizontal symmetry
Horizontal symmetry means the top and the bottom of an object look the same when divided in the middle. The dividing line is called the horizontal line of symmetry.

Reflection
Every morning, we look in the mirror. What do we see? We see a reflection of ourselves in the mirror.
We can also see our reflection on any shiny surface, like glass or even water.

The line between the object and the reflection is called the mirror line or the line of reflection
The mirror line or line of reflection can be of two types—vertical or horizontal. You can see the example below.
Reflection can be seen in nature as well. Look at the beautiful reflection of the mountains.

10 Length, Weight and Capacity
Length
Sharma Bakery is famous in the neighbourhood. Vibhu’s mom often sends him to get bread for the house. The shop is just a few metres away from their home.
Vibhu reads the signboard which says, “Free delivery up to 3 km. Order now!”.
Vibhu asks his Mother, “Mom, how far is 3 kilometres?”
Let us help Vibhu to find it out!
Measuring Length
We often need to know how far places are, or how long or tall things are. This is referred to as lengths or distances. This is exactly what Vibhu is asking his mother about.
For example, when Vibhu is walking from home to the neighbourhood bakery and back, he is walking a distance of a few metres. Similarly, when a delivery boy travels to another locality, he is travelling a distance of some kilometres.
Converting Between Units of Length
Metres (m) and kilometres (km) are units for measuring length. Kilometres are a larger unit than metres and are used to measure longer lengths, like the length of a road or the distance between 2 cities.
To measure shorter lengths, we use millimetres (mm) and centimetres (cm), like the length of a pencil or a paper strip. We can use a ruler or a measuring tape to measure different lengths. A ruler measures the length in millimetres (mm) and centimetres (cm), while a measuring tape measures the length in centimetres (cm) and metres (m).
ControlCopy
Remember!
Units of length: Millimetre (mm) < Centimetre (cm) < Metre (m) < Kilometre (km)
“Fresh bread and buns. I must hurry back home.”
Did You Know?
The Ganga river is about 2525 km long. It is the longest river in India.
To get the correct and simple measurement, sometimes we need to change the units of length from one to another. Let us learn the relationship between different units of length. 1 cm = 10 mm 1 m = 100 cm 1 km = 1000 m
Changing to larger units
To change to a larger unit, we divide.
ControlCopy
Changing to smaller units
To change to smaller units, we multiply.
From the above table, we know that 1 km = 1000 m Hence upto 3 km free delivery is = 3 × 1000 = 3000 m.
Example 1: Suggest the right tool and find the length of the line.
This is a short line on paper. A ruler or a measuring tape can be used to measure the length. Let us use a ruler to measure the length of the line.
Place the ruler against the line. Make sure it starts at 0.
Note the length of the line in millimetres and centimetres. This line is 8 cm 2 mm long.
Example 2: Convert.
1 255 cm to m and cm.
255 cm = 200 cm + 55 cm
Remember, 100 cm = 1 m
So, 200 cm + 55 cm = 2 m 55 cm
2 1092 m to km and m.
1092 m = 1000 m + 92 m
Remember, 1000 m = 1 km
So, 1000 m + 92 m = 1 km 92 m
Solving Problems on Length
Let us solve some problems related to length in our daily lives.
Example 3: Priya is going to the dairy to get milk. If the dairy is 250 m away from her home, how far has she walked from home to the dairy and back?
250 m
The distance from the home to the dairy = 250 m
The distance from the dairy to the home = 250 m
So, the total distance Priya has walked = 250 m + 250 m = 500 m
Example 4: The Red Fort is about 1500 metres away from the Jama Masjid. How far is it in kilometres and metres?
1500 m = 1000 m + 500 m = 1 km + 500 m
So, the Red Fort is 1 km and 500 m away from the Jama Masjid.

Weight
ControlCopy
We often measure how heavy or light things are. This is referred to as weight.
Chintu wants to know how strong he is. In the garden, he picked up a feather first. “It is so light,” he said cheerfully.
But then he picked up a rock! “It is so heavy,” he cried. “How heavy is it?” he wondered.
Measuring Weight
Chintu could use a weighing scale to measure the weight of the rock. We measure weight in many other situations.
A seller measures the weight of fruit and vegetables on a weighing scale. A doctor measures our body weight on a weight machine before a check-up.
Did You Know?
Galileo was an Italian scientist who studied how objects move and how gravity works. His experiments helped us understand how to measure weight, which tells us how heavy something is.
Converting Between Units of Weight
On a weighing scale, different stones or bars are used. Look at the picture of kilogram (kg) bars. It is a measuring unit for weight.
Kilogram (kg), gram (g), and milligram (mg) are the units of measuring weight. A milligram (mg) is a small unit of weight measurement. A gram (g) is larger than a milligram (mg), and a kilogram (kg) is an even larger unit.
We usually use grams as a unit to measure smaller weights, such as spices. We use kilograms to measure our body weight.

Make sure the needle of the scale is at 0 when you start. Place the object (a watermelon) on the machine.
Now, note where the needle is on the scale. The weight of this watermelon is 2 kg.
Example 6: Change the units of weight.
1 Change 1050 mg to g and mg.
1050 mg = 1000 mg + 50 mg
Remember, 1000 mg = 1 g
So, 1000 mg + 50 mg = 1 g 50 mg
Solving Problems on Weight
2 Change 2090 g to kg and g. 2090 g = 2000 g + 90 g
Remember, 1000 g = 1 kg

Let us solve some problems on weight in our daily lives.
Example 7: Nishant has 7 oranges of about the same size. The weight of 2 oranges is 200 g. What is the total weight of all the oranges?
Weight of 2 oranges = 200 g
Weight of 1 orange = 200 ÷ 2 = 100 g
Weight of 7 oranges = 7 ×
Example 8: Mihir's uncle bought 8 packs of pulses, each weighing 500 g. What is the weight of the pulses he has bought in kilograms (kg)?
Weight of 1 pack of pulses = 500 g
Weight of 8 packs of pulses = 8 × 500 = 4000 g
We know that 1000 g = 1 kg
So, 4000 g = 4000 ÷ 1000 = 4 kg

Rima is visiting a supermarket. She wants to buy some juice for a party. There are different bottles with different amounts of juice. She wants to buy the bottles with the greatest amount of juice. Let us help her!
Measuring Capacity
We know how to measure the weight of solids, such as fruit and vegetables, but we do not measure liquids such as water, milk and juice in the same way.
Rima needs to check the ‘capacity’ of each bottle written on its labels to know how much juice it holds. Bottles, packets, glasses and other utensils are made to hold different amounts of liquid. Thus, they have different capacities.
Converting Between Units of Capacity
Different measuring cups or jars are used to measure different capacities. Millilitre (mL), litre (L) and kilolitre (kL) are the units of measuring capacity.
A millilitre (mL) is a small unit of capacity. Litre is bigger than mL, and kilolitre (kL) is even greater.
We usually find water bottles, cans and jars with a litre capacity. Medicinal droppers, cups, and syringes measure liquid syrups and medicines in mL.
Let us learn the relationship between different units of measuring capacity.
1 L = 1000 mL
Let us see how to convert between units of weight.
Change Litres (L) to Millilitres (mL)
Change Millilitres (mL) to Litres (L) ×
Example 9: Measure 1 litre of water using a measuring jug.
ControlCopy
Remember!
Capacity is the amount of liquid a container (bottle, glass, etc.) can hold. L
Slowly pour the water into the jug.
Stop when it reaches the mark of 1 litre.
Let the water settle and read again.
This jug contains 1 litre (L) of water.
Example 10: Convert.
1 3050 mL to L.
Remember, 1000 mL = 1 L
So, 3050 mL = 3000 mL + 50 mL = 3 L 50 mL
Solving Problems on Capacity
2 8 L to mL.
Remember, 1 L = 1000 mL
So, 8 L = 8 L × 1000 mL = 8000 mL
Let us apply our learnings in solving some problems on capacity in our daily lives.
Example 11: This evening, Anju’s mother is making mango shake for Anju and 4 of her friends. Each glass can hold 250 mL of mango shake. How much shake does she need to prepare to serve Anju and her friends?
1 glass = 250 mL
For 5 people, we need 5 glasses of shake.
5 glasses would contain = 5 × 250 mL = 1250 mL.
So Anju’s mother needs to prepare 1250 mL of shake.

Example 12: Simran is buying water bottles at a market. Each bottle has 250 mL of water. She needs 2 L of water. How many bottles does she need to buy?
We know that 1 L = 1000 mL
2 L = 2000 mL
If 250 mL = 1 bottle
Then, 2000 mL = 2000 ÷ 250 = 8 bottles
So, to get 2 litres of water, Simran needs to buy 8 bottles.

It is Rita’s parents’ 15th wedding anniversary! She wants to give them a family photo, but the frame has a plain brown edge. Rita doesn’t like it and decides to paste a colourful ribbon over it. How will she know how much ribbon is needed?
ControlCopy
Perimeter
Rita needs to cut a piece of ribbon that is the same length as the edge of the frame. The total length of the frame around the photograph is the perimeter of this photo frame.
The perimeter is the total distance covered along the edges of a closed figure or shape. It can be measured in millimetres (mm), centimetres (cm) and metres (m).
Some real-life examples where we need to find the perimeter include:
• Making or decorating the edges of a photo frame, a gift box or a scarf.
• Putting fencing around a house, building, park, farm or field. Decorated boundary
Finding Perimeter Using a String
Let us see how we can measure the length of the boundary of an irregular shape.
Step 1
Place the thread along the edge of the shape, as shown in the picture.
Step 2
Mark the end point on the thread where it meets the starting point. You may mark or cut the thread at this point.
Step 3
Use a ruler to measure the length of the piece of thread. The length of the thread is the perimeter of the shape.
Finding Perimeter Using Squared Paper
We learnt to find the perimeter of irregular shapes. What if we need to find the perimeter of shapes with straight edges? We can do so by using squared paper.
Below are two polygons on squared paper. To find the perimeter, we count the number of squares around the polygons.
ControlCopy
Both the figures have different shapes but the same perimeter of 20 units.
Remember!
A polygon is a closed figure that is made up of only line segments.
Example 1: Find the perimeter of the following shapes.
Finding Perimeter of Polygons
To find the perimeter of polygons such as a triangle, square or rectangle, we can simply add the lengths of all the sides.
For example: The perimeter of figure A and figure B can be given as:
What if the perimeter of a figure is given and we need to find one of the missing sides?
To do so, we add the lengths of the sides given and then subtract them from the perimeter. Let us understand this with examples.
Example 2: Find the missing length of the side if the perimeter of this shape is 23 cm.
Given, the perimeter = 23 cm
This means,
4 cm + 5 cm + 8 cm + the length of the missing side = 23 cm
17 cm + the length of the missing side = 23 cm
So, the length of the missing side = 23 cm − 17 cm = 6 cm
Example 3: Sunita took 2 rounds of the given rectangular park. How much distance did she cover in total?
Distance covered in one round = Perimeter of the park

Area
Rita’s beautiful photo frame is ready! Now she needs to print a picture that fits perfectly in the frame.
The space within the boundaries of the frame on which the photo needs to fit is the area of the photo frame.
So, the area is the total space covered by a closed figure. We need to know the area in the following situations:
• Area of a wall that needs to be painted.
• Area of a floor to check if it can be covered with carpets or tiles of certain sizes.
• Area of land while dividing it into parts for different uses.
Area is measured in square units, that is, square centimetres (sq. cm) or square metres (sq. m).
Finding Area Using Squared Paper
We learnt to find the perimeter of a polygon using squared paper. We can also find the area of a polygon on a square grid.
Let us look at the figure below and find out its area, where the side of 1 unit = 1 cm.
The area of 1 square = 1 unit × 1 unit = 1 square unit.
We can find the area by counting the number of squares covered by the shape .
Did You Know?
Honeybees use hexagons to build their hives so that their storage space (area) is maximised, and the perimeter is minimised.
Number of units covered by the shape = 9.
1 unit = 1 cm. So, the area of the shape = 9 square cm.
Area of Irregular Shapes
Like other shapes, irregular shapes are those that are not made entirely of complete squares. Some squares are partly covered. For example, look at the shapes A and B given below.
Half squares 1 cm 1 cm
More than half squares Less than half squares
Shape A Shape B
In shape A, there are half squares and complete squares, whereas in shape B, there are half squares, less than half squares and more than half squares. In such cases, we can only find the approximate area using the rules:
1 Complete squares are counted as 1.
2 All half squares are counted as 1 2 .
3 All more than half squares are counted as 1.
4 All less than half squares are ignored.
The total count of all kinds of squares gives the approximate area of irregular shapes. Now, let us find the areas (approx.) of shapes A and B using these rules.

Yesterday, the clock in Noor’s room was showing 8 o’ clock at night. Now, it is showing 8 o’ clock in the morning. Let us find out how the wall clock shows the same time twice each day. morning 08:00 08:00 night
A full day has 24 hours in total, while a clock shows only 12 hours. So, the hour hand on a clock completes two rounds. As a result, each time is shown twice a day. In the same way, a day can be divided into two equal halves to read the time.
The new day by the clock starts at 12 o’ clock at midnight
Reading Time on a Clock
We already know how to read time on an analogue clock. There are analogue clocks and digital clocks. Let us read time to the minute on an analogue clock.

The time on the clock is 7:22.
When the minute hand moves from one small marking to the next, 1 minute has passed.

“But how do we read time on this clock? How do we know if the time is a.m. or p.m.?” Divya is curious.
Let us learn about this different format of reading time.
Reading a 24-hour Clock
A digital clock is a 24-hour clock.
It shows time in the format of 00:00. The first two digits show the hours, and the next two digits show the minutes.
A 24-hour time clock uses numbers from 1 to 23 to show 24 hours of a day. 1 to 12 represent the first 12 hours of the day and 13 to 23 show hours after 12 noon or 12 p.m.
On a digital clock, we read time in ‘hours’ units. For example, the time on this clock will be read as 14:05 hours.
Time after 23:59 is read as 00:00 and not 24:00.
24:00 00:00

Remember!
Time in the 24-hour format can be read as 13:00 hours or 1300 hours. Both ways are correct and mean the same.

Changing
12-hour Clock to 24-hour Clock Time
Railway and airline timetables use 24-hour formats or digital clocks. But our regular
analogue clocks use the 12-hour format. Therefore, it is important to learn how to convert time in the 12-hour format into the 24-hour format.
Changing time in a.m. to 24-hour clock:
Let us change 9:30 a.m. into 24-hour format.
Step 1
Keep the same hour value. For 9:30 a.m., the hour value is 9 or 09.
Step 2
Write the minutes as they are. For 9:30 a.m., the minute are 30.
So, 9:30 in 24-hour time will be written as 09:30.
Changing time in p.m. to the 24-hour clock:
Now, let us learn to change 10:30 p.m. into the 24-hour format.
Remember!
Step 3
Now, replace a.m. with hours.
Thus, time in 24-hour format is 09:30 hours.
In a 24-hour format, 12 midnight is written as 00:00, and 12 noon is written as 12:00 hours.
Step 1
Add 12 to the hour value.
Here, hour value = 10. So, the value = 10 + 12 = 22.
Step 2
Write the minutes as they are. Herethe minutes are 30. So, in the 24-hour format 10:30 = 22:30.
Example 4: Change 3:30 a.m. to 24-hour time.
Keep the same hour value : 3
Write the minutes as they are : 3:30
Replace a.m. with hours : 03:30 hours
Example 5: Change 6:45 p.m. to 24-hour time.
Add 12 to the hour value : 6 + 12 = 18
Write the minutes as they are : 18:45
Replace p.m. with hours : 18:45 hours
Step 3
Replace p.m. with hours.
Thus, the time in the 24-hour format = 22:30 hours.
ControlCopy
Example 6: Liftoff for a school’s drama “Mission to Mars” is scheduled for 9:15 p.m. Express this time in the 24-hour format so the spaceship’s clock can be set correctly.
Add 12 to the hour value: 9 + 12 = 21
Write the minutes as they are: 21:15
Replace p.m. with hours: 21:45 hours
Thus, the time in the 24-hour format is 21:45 hours.
Changing 24-hour Clock to 12-hour Clock Time
Let us learn how to change the 24-hour clock time to 12-hour clock time.
Step 1
Look at the first two digits of the time.
• It is a.m., if the number is less than 12.
• It is p.m., if the number is more than 12.
Example 7: Change 11:30 hours into 12-hour time.
Step 2
For a.m. time, keep the hour value as the first two digits. For p.m. time, subtract 12 from the first two digits.
The first two digits of the time are 11. Since it is less than 12, it is a.m. time.
For a.m. time, keep the same hour value as the first two digits, which is 11.
Write down the minutes as they are. So 11:30 hours by a 12-hour clock is 11:30 a.m.
Step 3
Write down the minutes as they are.
Example 8: Change 13:00 hours into 12-hour time.
The first two digits of the time are 13. Since it is more than 12, it is p.m. time.
For p.m. time, subtract 12 from the first two digits: 13 – 12 = 1.
Write down the minutes as they are:
So 13:00 hours by a 12-hour clock is 1:00 p.m.
Example 9: Astronauts on the International Space Station (ISS) follow a 24-hour clock. If dinner is served at 19:00 hours, what time is that in the 12-hour format?
24-hour clock time = 19:00 hours
Time in hours = 19 – 12 = 7.
Time in minutes = Remains the same = 00
So, 19:00 hours by a 12-hour clock is 7:00 p.m.

Siya attends a music class from 4:30 p.m. to 6:30 p.m. every Sunday. The duration of her class can be found by calculating the time between these two points.
hour 1 hour 5:30 p.m. 4:30 p.m. Start time 6:30 p.m. End time Duration or time taken for music class = 2 hours
We can get duration in hours or minutes. We can also change time from minutes to hours and from hours to minutes.
Remember!
1 hour = 60 minutes. Division is the opposite of multiplication. To change hours to minutes, we multiply the hour by 60. To change minutes to hours, we divide the minutes by 60.
Example 10: 1 Change 4 hours to minutes.
1 hour = 60 minutes
So, 4 hours = 4 × 60 minutes = 240 minutes.
Add or subtract hours and minutes separately. 2 hours + 2 minutes = 4 hours OR = 4 minutes 2 hours + 2 minutes = 2 hours and 2 minutes
2 Change 186 minutes to hours and minutes.
60 minutes = 1 hour
So, 186 minutes = 186 ÷ 60 = 3 hours 6 minutes.
Example 11: The teacher is telling the students about an upcoming test. The test will be 2 hours long. The first 20 minutes will be for reading the questions. How many minutes will be left for writing the answers?
Total time for the test = 2 hours

Time in Days, Weeks, Months and Years
Let us look at the calendar to understand the different units like days, weeks, months and years to see how they are related.
Days in Week
7 days make a week. In the calendar above, the week starts on a Sunday and ends on a Saturday.
Have a look at the calendar for the month of May. The first full week of this month starts from Sunday, May 1 and ends on Saturday, May 7. This makes a week.
The same days of the week repeat every 7 days. So, if April 5 is a Tuesday, then the next Tuesday will be 5 + 7 = 12 April.
In the same way, if 18 July is a Monday, then the previous Monday was on 18 − 7 = 11 July.
Think and Tell
1 day has 24 hours. How many hours are there in a week? Can you tell the total minutes in a week too?
Days in a Month
Remember!
The same day repeat after every 7 days. For example, if today is Monday, it will be Monday again after 7 days.

We know that there are 12 months in a year. These months have 28, 29, 30 or 31 days.
Did You Know?
You can count the number of days in a month using your fist! The top of the knuckles shows months with 31 days and the hollows between the knuckles show months with 30 days and 28 or 29 days of February. We start with the top knuckle of our little finger.
Days in a Year
There are 365 days in a year.
4 × 30 days = 120 days 7 × 31 days = 217 days 1 × 28 days = 28 days
Adding all the days of the year: 120 + 217 + 28 = 365 days
If it is a leap year, February will have 29 days. Then, the year will have 366 days instead of 365 days.
Remember!
A leap year is a year that has one extra day added to it. It occurs every fourth year. Number of days in a leap year = 365 days + 1 day = 366 days.
Each year starts with January and ends with December. So, the year 2022 ends on 31 December 2022, and the new year begins on 1 January, 2023.
A calendar is the record of all the days and months of a year. We read them as dates. We can write the date in short form using the format Date Month Year. For example, 18 July 2023 can be written as 18.07.2023.
Example 12: Gokul’s birthday is two weeks after Independence Day which is on 15 August, and happens to fall on Friday this year. When is Gokul’s birthday?
Independence Day is on 15 August.
1 week = 7 days. So 2 weeks = 14 days
Gokul’s Birthday = 15 August + 14 days = 29 August
Since 15 August is a Friday, 29 August will also be a Friday. Thus, Gokul’s birthday is on Friday, 29 August.
Example 13: How many days are there between January 18 and February 12?
Total days in January = 31 days
Days remaining in January = 31 – 18 = 13 days
Days in February = 12 days
So, total days = 13 + 12 = 25 days.

Mother: We have come to withdraw some money from the ATM.
ControlCopy
After the withdrawal, a slip came out of the machine.
Rohan: What is written on this slip?
Mother: The slip shows the money left in our bank account.
Rohan saw that the amount left in the bank account was ₹648.65.
Reviewing Rupees and Paise
Rohan was wondering how to read the amount. Let us learn how to read the amount.
Express Money in Words
When reading the amount in words, we read the left part in rupees, and the right part in paise. So, ₹648.65 can be expressed in words as “six hundred forty-eight rupees and sixty-five paise”.
The number on the left of the dot shows rupees.
The number on the right of the dot shows paise.
The dot separates the rupees and paise. ₹648.65
Example 1: How will you write these amounts in words?
₹255.84
₹157.06 2 1
₹255.84
Rupees Paise
₹255.84 = Two hundred fifty-five rupees and eighty-four paise.

₹157.06
Rupees Paise
₹157.06 = One hundred fifty-seven rupees and six paise.
Example 2: Write three hundred fifty-eight rupees and nine paise in figures.
Three hundred fifty-eight rupees = ₹358
Nine paise = 09
Three hundred fifty-eight rupees and nine paise = ₹358.09
Conversion Between Rupees and Paise
Money can be converted from rupees to paise and vice versa. Let us convert ₹1229.54 into paise.
Step 1
Remove the dot and ₹ sign.
₹1229.54 = 122954
Step 2
Write paise with the number. Therefore, ₹1229.54 = 122954 paise.
We can also convert paise into rupees. Let us convert 151236 paise into rupees.
Step 1
Remove the word ‘paise’ and put a dot after counting 2 numbers from the right of the number.
Example 3: Convert ₹4236.25 to paise.
Step 1
Remove the dot and ₹ sign.
₹4236.25 = 423625.
Step 2
Put the sign of ₹ before the number.
Therefore, 151236 paise = ₹1512.36. 151236 1512.36 ₹1512.36
Step 2
Write paise with the number. Therefore, ₹4236.25 = 423625 paise.

Sam and his family spent ₹680 on lunch. On the way back home, they purchased vegetables for ₹512 and groceries for ₹436. Sam’s father had ₹2000 with him. How much money did he have left?
As we need to find the money Sam's father has left, we first need to find out how much money he spent.
Amount spent on lunch = ₹680
Amount spent on vegetables = ₹512
Amount spent on groceries = ₹436
Total money spent = ₹680 + ₹512 + ₹436 = ₹1628
Amount Sam's father has left = Total amount – Amount spent = ₹2000 – ₹1628 = ₹372
Example 8: Each student of a class contributed ₹115 for flood victims. If there are 37 students in the class, what is the total amount of money collected?

He started piling the coins, one upon the other, in the following order: ₹1, ₹2, ₹5, ₹10, ₹1, ₹10, ₹2, ₹5, ₹1, ₹10, ₹1, ₹1, ₹1, ₹2, ₹10, ₹5, ₹5, ₹2, ₹1, ₹1, ₹2, ₹10, ₹1, ₹1, ₹2, ₹5, ₹2.

If we have to count each type of coin from this list, it will be hard. Is there an easier way? Let us learn that.
Tables and Tally Marks
We can organise the types of coins that Rahul had in a tally marks table. Let's do it step by step.
Step 1
Write each unique type of coin in a table.
Step 2
Each time you take a coin put a mark next to its type, as shown in the table.
The table below shows the first four entries: ₹1, ₹2, ₹5, ₹10.
Coins Tally Marks
|
|
These marks are called tally marks
Step 3
Put in the tally marks one by one for each coin.
Coins Tally Marks
₹1 |||| ||||
₹2 |||| ||
₹5 ||||
₹10 ||||
Note that when the number of tally marks exceeds 4, we use |||| and not |||||. So, bunches of |||| form 5s. This makes it easier to count and find totals in tables.
Step 4
Finally, put the totals in a new column.
Similarly, any kinds of data can also be organised with the help of pictures, graphs, tables, etc. This way of organising data is called data handling
Data handling is the process by which data is arranged in a systematic way.
Example 1: Rahul visited a zoo on Sunday with his parents. He used tally marks to count and record the number of different types of animals he saw there. Look at the table and answer the following questions.
1 Which animal did he see the greatest number of in the zoo?
Rahul saw the greatest number of elephants.
2 How many tigers and deer were there in the zoo?
In the zoo, there were 3 tigers and 4 deer.
3 What is the difference in the number of leopards and zebras that he saw?
Number of leopards = 12
Number of zebras = 6
The difference in the number of leopards and zebras = 12 – 6 = 6.

Pictographs
Drawing and Reading Pictographs
It was Rahul's birthday. He wanted to treat his 10 friends to a pizza party. He told them about the three types pizza toppings that they could choose for their pizza: cheese, vegetable, and paneer. He then conducted a survey to see how many of his friends liked each topping. After that, he wanted to represent this data as pictures. How do you think he would do that? Let us find out.
Creating Pictographs
Rahul created a pictograph based on the above data. Study the pictograph below.
Toppings Number of Friends
Cheese
Paneer
Vegetable
= 1 friend
The symbols that are drawn in a pictograph should be of the same size. Error Alert!
Rahul thought of conducting the same kind of survey in his class that has 32 students. The type of pizza liked by each student was recorded as follows.
Cheese, Paneer, Chicken, Mushroom, Vegetable, Paneer, Vegetable, Cheese, Paneer, Chicken, Vegetable, Mushroom, Chicken, Paneer, Cheese, Chicken, Vegetable, Paneer, Cheese, Chicken, Paneer, Vegetable, Cheese, Mushroom, Vegetable, Paneer, Chicken, Chicken, Paneer, Cheese, Mushroom, Chicken.
Let us draw a pictograph for the data.
The key for this pictograph could be:

We use a key to denote the value of the symbol.
The key helps us to represent large values of data easily on a pictograph.

Bar Graphs
Rahul went to watch a cricket match. He noticed that different runs are made in different overs. He wants to compare the runs scored in each over. He wondered if there was any way by which he could compare the runs quickly and effectively.
The chart below shows the runs made in the first 6 overs.
Drawing and Reading Bar Graphs
Rahul realised that data representation by pictograph is not only time-consuming but at times difficult as well.
He wanted to find an easier and better visual form of representation of the data. What could be an easier way to do this? Bar graphs!
Creating Bar Graphs
We know that bar graphs are one of the simplest ways to represent data by using numbers and rectangular bars.
Steps to make the bar graph for the runs scored:
1 Draw horizontal and vertical axes.
2 On the horizontal axis, put the overs.
3 On the vertical axis, put the runs in intervals of 1.
4 Draw the rectangular bars.
Remember!
The title explains what the graph is about (Example: runs per over).
The scale is the number that shows the units used (Example: 1 division = 1 run).
Labels show what kind of data is shown (Example: runs, overs).
ControlCopy
Example 4: The table below shows information about the marks (out of 50) obtained by five students in a recent test.
To create a bar graph for this data, we need to:
• firstly, draw horizontal and vertical lines;
• then, on the horizontal axis, we put the names of the students and on the vertical axis, we put the marks obtained by the students;
• and finally, we take 1 unit length to represent 5 marks.

Sam Sonia Anita Tania
Interpreting Bar Graphs
Remember, Rahul wanted to identify the most and least runs scored in an over!
From the graph,
Most runs in an over = the tallest bar = 9 runs
Over in which the most runs are scored = 6th over
Least runs in an over = the shortest bar = 4
Over in which the least runs are scored = 1st over
Example 5: The following bar graph shows the monthly expenditure of a family on vegetables (in ₹). Read the graph and answer the questions below.
Expenditure of a Family
1 Which month has the least expenditure?
From the graph, the height of the bar is the lowest in the month of September.
Thus, in September, the family’s expenditure is the least.
2 What is the expenditure in the month of March?
The expenditure in the month of March = ₹1800.

Pie Charts
The teacher assigns a recycling project to the class that promotes a clean environment.
As part of a recycling project, Aarti and her two friends collect plastic holders.
The three friends collect 40 holders altogether. Aarti wonders how many holders each of them collected.
The number of holders collected is shown using a pie chart or circle graph.
Aarti has collected 1 4 of the total holders while Mohan has collected 1 2 of the total holders.
Number of holders collected by Aarti = 1 4 of 40 = 40 ÷ 4 = 10
Number of holders collected by Rahul = 1 4 of 40 = 40 ÷ 4 = 10
Number of holders collected by Mohan = 1 2 of 40 = 40 ÷ 2 = 20
10 + 10 + 20 = 40 holders

Let us recite a poem together! The sun that shines, the rain that falls, The whispers of the wind that calls. Every creature, big and small, A part of nature, loved by all.
Let's protect this earth we share, Show we truly, deeply care. For clean air and water pure, A healthy world, let's ensure.
Our Environment
Shashi goes to picnic at the park with her family. After reaching the park, Shashi tells her mother, “Mumma, this place is so beautiful! I wish it always remains like this.” To this, her mother replies, “Yes, you are right. It is beautiful. And it is our responsibility to keep it like this forever. For this, we need to protect our environment.”
Our environment includes everything around us. It consists of both living and nonliving things. We depend on our environment for many things.
• We get food, water and air from the environment.
• We also get medicines, gum, paper and other useful things from it.
But humans have become greedy and caused harm to the environment to get more of everything that it offers. The forests have been cut down to make houses, malls, roads and buildings. Animals are being slaughtered for their fur, leather, teeth and horns.
Pollution
Remember!
The environment includes the air we breathe, the water we drink and the land on which we live.
Pollution is caused by the addition of unwanted and harmful substances to our environment. These substances affect air, water and soil, making them unsafe for living things. These unwanted substances are called pollutants. Let us learn about the different types of pollution.
Air Pollution
When harmful substances like smoke and chemicals are released into the air, making the air dirty and unfit for breathing, it is called air pollution. Causes of air pollution:
• Burning of fuels such as petrol, diesel and coal.
• Emission of smoke and other harmful gases from factories and automobiles.
• Burning waste in open areas.
Air pollution can cause serious health problems to humans, and harm animals and plants as well. When harmful gases in the air mix with rain, it results in acid rain. This rain damages buildings, and harms plants and animals as well.
Steps to control air pollution:
• Use more public transport like buses and trains.
• Use vehicles that run on green fuels like CNG.
• Plant more trees.
emission: the release of something as gas or particles in air or water slaughtered: killed in a way that is cruel and unnecessary

Air Pollution
Investigate and Discover
Aim: To understand how air pollution affects cotton balls kept in different locations
Materials Needed: 2 cotton balls, 2 transparent jars or containers
Method:
Step 1: Place one cotton ball in a jar and keep it in a room. Place the second cotton ball in another jar and leave it outside your home at a place facing a busy road with traffic. Do not close the lid of the jar.
Step 2: After a few days, take out both the cotton balls and compare them.
Step 3: Note the differences in the appearance of the cotton balls.
Findings: We will see that the cotton ball that was kept outside turned more grey or brown in colour.
Conclusion: Air outside is polluted. This is proved on comparing the two cotton balls.
ControlCopy
Water Pollution
When harmful substances get into rivers, lakes, oceans and other water bodies, making it dirty and unsafe for living things, it is called water pollution.
Causes of water pollution:
• Human activities such as dumping waste and washing clothes in rivers and ponds.
• Factories and industries often release harmful chemicals and untreated waste into rivers, lakes and oceans.
All of this makes the water unfit for human consumption and causes diseases like typhoid, cholera and dysentery. It also harms the plants and animals that live in or depend on that water body.
Steps to control water pollution:
• Avoid disposing of waste and untreated chemicals into water bodies.
• Ensure dirty or waste water is properly treated before releasing it into rivers, lakes or oceans.
Did You Know?
The River Ganga is one of the most polluted rivers in the world due to industrial waste and sewage. In 2014, the Government of India started a special program called the Namami Gange project. This project aims to clean the river and make its water safe again.
• Use fewer chemicals like pesticides and fertilisers, as these can seep into water sources and pollute them.
Water Pollution
Land Pollution
The addition of harmful substances into soil is called land or soil pollution.
Causes of land pollution:
• Throwing wastes like food waste, plastics and glass in open areas.
• Improper discarding of electronic wastes like old computers, phones and batteries.
• Discarding chemical waste from factories in agricultural fields. Chemicals spoil the quality of the soil and pollute it.
As the soil gets damaged due to land pollution, it affects the growth of trees, plants and crops.
Steps to control land pollution:
• Sort household waste as wet waste and dry waste for proper disposal.
• Dump wastes like fruit and vegetable peels into pits to turn into manure.
• Use manures instead of fertilisers and pesticides in farms.
Pause and Answer
Write the type of pollution caused by the following.
1. Smoke from factories and vehicles.
2. Dumping garbage in a river.
3. Throwing plastic bottles in an open ground.
Waste Management
Types of Waste
Wastes can be of two types: biodegradable and non-biodegradable.
• Biodegradable wastes are the wastes that easily decompose and mix with the soil. For example, fruit and vegetable peels, leftover foods, paper, plant leaves and eggshells. We can throw biodegradable waste into soil pits where it can change into manure. These pits are called compost pits. Biodegradable Wastes
discarding: throwing away fertilisers: chemicals added to fields to help plants grow pesticides: chemicals added to fields to kill animals and insects that eat away crops
ControlCopy
Land Pollution
• Non-biodegradable wastes are the wastes that do not decompose and mix with the soil. Examples of non-biodegradable wastes are plastic, glass and metals.
Think and Tell
Imagine you are on a picnic and you have leftovers, a plastic bottle and some paper napkins. Which items would you throw in a compost pit?
The 3Rs
Non-biodegradable Wastes
One day, Riya found an old pickle jar in the kitchen. Instead of throwing it away, she cleaned it, and turned it into a beautiful pencil holder. She showed it to her teacher the next day. The teacher was really happy. She explained to the class, “The way Riya recycled the old jar into a pencil holder, in the same way, we can also reuse and recycle things to reduce wastage, and help save the environment.”
Let us learn about some important ways to save our planet.
Reduce
It means to decrease the use of things that release harmful substances in the environment. By reducing waste, we keep our environment clean and save our natural resources. For example:
• Use cloth or jute bags instead of plastic bags.
• Use metal spoons and straws instead of plastic ones.
Reuse
It means finding new ways to use old items instead of throwing them away. This helps save our money and resources. For example:
• Use glass jars to store food.
• Reuse old boxes to store things.
Recycle
ControlCopy
Paper, plastic, glass and metal wastes should be sold to the scrap dealer and sent for recycling. In recycling units, they are turned into new products. This saves money, water and other resources that go into making new items. Recycling reduces pollution in the environment. For example:
• Paper is recycled into tissue paper or handmade paper.
• Tin cans are recycled to make new cans.
scrap dealer: a person who buys and sells old things
A jute bag
Glass jars to store food
Paper for recycling
Write ‘B’ for biodegradable wastes and ‘N’ for non-biodegradable wastes.
Green Surroundings
Trees play a key role in keeping the environment clean and green. They keep the air fresh by adding oxygen to it. They also keep the surroundings cool as they release water vapours through leaves. Trees also hold the soil tightly and stop soil erosion.
However, we cut down trees to get paper, rubber and wood. The large scale cutting down of trees is called deforestation. Deforestation harms our surroundings and destroys the natural habitat of animals.
Saving Trees
Did You Know?
It takes an entire tree to create just 3 to 4 textbooks.
To save our environment, we need to plant more trees than we cut down. Planting trees in large numbers is called afforestation.
In India, Van Mahotsav is celebrated for a week every year in July. During these seven days, millions of trees are planted across the country, promoting afforestation and environmental awareness.
We should also use paper wisely because a lot of trees are cut down to make paper. Reusing and recycling paper saves a lot of trees.

What is Weather?
Weather is the condition of the atmosphere at a particular place and time. Has it ever happened that you were out and it was dark and cloudy, but suddenly it became bright and sunny? This happens because weather can quickly change from day to day and hour to hour. Weather can be hot, cold, windy, dry or humid.
It is always useful to know the weather beforehand so that you can plan your day better. If you know it is going to rain, you will take an umbrella with you. Scientists who study, observe and forecast the weather are known as meteorologists.
Climate is the weather pattern of a specific place for a longer period of time. We know that the climate of hilly areas is generally cold and chilly, while deserts have a hot and dry climate.
Did You Know?
Crickets chirp more frequently as the temperature rises. That is why we can hear more crickets chirping in summer evenings.
Factors Affecting Weather
Ravi lives in Chennai. He was playing outside in the sun when he got a call from his cousin Tara, who lives in Kashmir. Tara excitedly told Ravi that it was snowing in Kashmir. Ravi wondered why the weather was so different at these two places at the same time.
The weather of a place depends upon different factors. Let us know about some of them.
• Distance from the sea: Seas get heated up and cooled down at a slower rate compared to land. That is why coastal areas are cooler in summer than areas which are far from the sea. Similarly, coastal areas are warmer in winters than other areas.
• Sunlight: It heats up the Earth, making its surface and the surrounding atmosphere warmer. This, in turn, affects the weather of a place.
• Humidity: It is the amount of water vapour present in the air. Generally, the areas with high humidity are warmer, while those with low humidity are cooler.
• Clouds: Clouds can block the heat and light from the Sun reaching the Earth’s surface, making that area cooler.
• Wind: Fast moving air is called wind. Depending on the direction the wind blows, it brings hot or cool air. This, in turn, affects the weather of a place.

The Role of the Sun
The Sun plays an important role in causing weather changes. At noon, it is directly overhead, making the weather hotter. Conversely, during the morning and evening, the sunrays strike the Earth at a slant. As a result, the Earth’s surface does not heat up as much. Therefore, afternoons are generally hotter than mornings and evenings.
The positions of the Sun during the day.
ControlCopy
The Sun is not the only factor that determines the weather of a place. Other factors, like cloud cover and green cover, can also affect the weather.
Circulation of Air
When the sun shines brightly, it not only heats up the land but also the air above that area of land. When air heats up, it becomes lighter and rises above. Heavier and cooler air rushes in to take its place. This movement of air causes the winds to blow.
Breeze: Gentle wind is known as a breeze.
Gale: Strong wind is known as a gale.
Storms: Very strong winds are known as storms.
Think and Tell

Sea Breeze
During the day, the sun heats up the land and also the air above it. Since land heats up faster than water, the air above the land becomes warm and rises up. As a result, the cool air from the sea rushes towards the land. This movement of air from the sea to the land is called sea breeze.
Land Breeze
During the night, the land cools down faster than the sea. This makes the air above the land cooler, while the air above the sea stays warmer. As a result, the cool air from the land rushes towards the sea. This movement of air from the land to the sea is called land breeze.

Water is an important part of our everyday lives. It exists in three major states: solid (ice), liquid (water) and gas (steam or water vapour).
Water Cycle
The water cycle is the continuous movement of water from the earth’s surface to the sky and back again. There are four stages involved in the water cycle: evaporation, condensation, precipitation and collection. Let us learn about them.
• Water in different water bodies gets heated up by sunlight and changes into water vapour. This process is called evaporation.
• When water vapour moves up in the atmosphere, it cools down into water droplets, which combine to form clouds. This process is called condensation.
• When clouds become heavy with water droplets, the water falls back to the earth in the form of rain or snow. This process is called precipitation.
• The water falling on the ground flows into different water bodies like rivers, oceans, lakes and ponds. This process is called collection. The entire process of the water cycle is repeated again.

Step 2: Place the container in the sun and leave it undisturbed for a few hours.
Evaporation of Water
Step 3: Observe the water level in the container after a few hours.
Findings: The water level in the container goes down. The water gets heated up due to the sun’s heat and eventually evaporates.
Conclusion: The above experiment shows how water evaporates due to the heat of the sun.
Types of Precipitation
When water falls on the ground in any form, it is called precipitation. Let us learn about its types.
• Rain: It is the liquid form of precipitation. When clouds become heavy, water falls down in the form of rain.
ControlCopy
• Snowflakes: At low temperatures, the water vapours in the clouds suddenly cool down and form tiny white crystals called snowflakes.
Rain
Snowflakes
• Hail: When water falling down as rain passes through the cold regions of the atmosphere, it freezes to form small ice balls called hail.
• Dew: After a cold night, we see tiny drops of water on leaves in the early morning. These water drops are called dew.
• Frost: At low temperatures, the dew freezes into tiny white crystals called frost.
Wonders of Bharat
• Fog or mist: Fog forms when water vapour condenses into tiny droplets around dust particles in the air, reducing visibility. Thin fog is called mist.

Heavy rains and snowfalls are common in the northern and far-eastern parts of India. The central part and the Thar regions receive scanty to no rainfall. The coast and the regions near it receive a healthy amount of rainfall. The heaviest rainfall in the world is in Mawsynram in Meghalaya.

What is Matter?
Matter is all around us. Everything you can see, touch, or feel is made of matter, including the air we breathe, the water we drink and the food we eat. Thus, matter is anything that has mass and occupies some space. The mass of an object tells us about the amount of matter present in it. We can feel the mass of an object as its weight when we carry it.
For example, tables, chairs, your school bag, water bottle, and air flowing in your classroom are all examples of matter. They all occupy space and have mass.
Physical Properties of Matter
Physical properties are the characteristics of matter that we can observe or measure without changing the substance itself. Some physical properties are mentioned below.
The tables and chairs have mass and take up space.
Remember!
All living and non-living things are made of matter.
• Colour: It is a property of matter that can be seen. For example, the red colour of apples and the blue colour of the sky.
• Size: It tells us how big or small an object is. For example, a basketball is big while a tennis ball is small.
• Shape: It tells us about the form of an object. For example, a round ball or a rectangular sheet of paper.
• Texture: It tells us how an object appears on touching. For example, silk is smooth while sand paper is rough.
• Volume: It tells us about the space that an object takes up. For example, a full cup of water and a half cup of milk.
• State: It tells us the form in which matter is. For example, a table is solid, milk is liquid, and oxygen is gas.
Different States of Matter
Matter is made of tiny particles called molecules. On the basis of the arrangement of molecules, matter can be classified into three different states: solid, liquid and gas. Let us learn about these states, one by one.
Solids
Try to press the chair you are sitting on. Can you change its shape? No, you cannot. That means the chair has a fixed shape. This state of matter is called a solid.
Some properties of solids are:
• The molecules in solids are tightly packed. Due to this, they cannot move. Therefore, solids have a definite shape that cannot be changed unless we cut or break them.
characteristics: qualities that help identify and describe something observe: look at carefully definite: fixed
ControlCopy
Molecules in Solids
• They have a fixed volume.
• They cannot flow.
• Most solids are hard and cannot be pressed. Some, like clay and dough, can be pressed easily and moulded into different shapes. This is because their molecules are less tightly packed as compared to other solids.
• Some examples of solids are table, chair, door, book and jar.
Liquids
Try pouring some water from a bottle into a glass. What do you notice? The water will take the shape of the glass. Now, pour the same water into a bowl. It will take the shape of the bowl. This means that water does not have a fixed shape. Instead, it takes the shape of the container in which it is placed. But, the volume of water in the glass and in the bowl will remain the same. This state of matter, that does not have a fixed shape but has a fixed volume, is called a liquid.
Some properties of liquids are:
• The molecules in liquids are not as tightly packed as they are in solids. Due to this, the molecules can move. Therefore, liquids do not have a fixed shape.
• They have a fixed volume.
• They can flow and hence are also called fluids.
• Some examples of liquids are juice, milk, water and oil.
Gases
ControlCopy
Let us take a balloon and fill it up with air. What happens? The air fills up as much space as it can inside the balloon. If you let the air out, it spreads out into the room. This shows that gases spread out to fill any space available to them. Thus, the state of matter that does not have a fixed shape or volume is called a gas.
Some of the properties of gases are:
• The molecules in gases are very loosely packed. Due to this, they can move freely. Therefore, gases do not have a fixed shape.
• They also do not have a fixed volume.
• They can flow, like liquids, and hence are also called fluids.
• Some examples of gases are air, gas filled in hot air balloons and footballs, and water vapour (steam) rising from boiling water.

2. The particles in this state of matter are very loosely packed.
3. This state of matter takes up the shape of the container in which it is placed.
4. A term used for substances that can flow.
Change of States
Certain things, when heated or cooled, can change their forms from one state to another. Let us learn about the different ways in which these changes of state can occur.
Melting
Mohit was making lemonade for himself. He took out the ice tray from the freezer and added some ice cubes to his lemonade. Then, he sat down to enjoy his lemonade. Meanwhile, he forgot to put the ice tray back in the freezer. After some time, he returned to the kitchen and observed that the ice cubes in the ice tray had turned into water. Do you know why that happened? It happened due to melting.
Melting of Ice
When a solid is heated, its temperature rises. The molecules inside absorb heat and begin to move more freely. This causes the solid to change into a liquid. This process is called melting. Here, ice turned into water by absorbing the heat from the surroundings.
ControlCopy
Freezing
What would happen if you fill an empty ice tray with water and keep it in the freezer for some time? The water will change to ice. This happens due to freezing. When liquid (like water) is cooled, its temperature drops. The molecules lose heat and come closer together. This process, of a liquid becoming a solid when cooled, is called freezing.
Evaporation
Rehaan was helping his mother hang wet clothes to dry in the sun. He asked her, “Why do clothes dry when we hang them in the sun, after washing?” She explained that due to the sun’s heat, the water from the wet clothes evaporate. That is why they dry. When a liquid is heated, its temperature rises, and the molecules move farther apart. This allows the liquid to change into gas. This process of liquid becoming gas when heated is called evaporation.
Condensation
Roshni put some water to boil in a pot and covered it with a glass lid. After some time, she removed the lid and saw tiny water droplets on the inner surface of the lid. This happened because when water vapour from the boiling water touched the cold surface of the lid, it condensed to form water droplets. Thus, when a gas is cooled, its temperature decreases and its molecules come closer together, turning the gas back to liquid. This process of a gas becoming a liquid when cooled is called condensation.
Sublimation
When a solid converts directly into gas on heating, without turning into liquid first, it is called sublimation. For example, when naphthalene balls are left in the open, they become smaller and smaller. This is because the solid naphthalene balls are evaporating directly instead of melting.
Think and Tell
Do you know why we use naphthalene balls?
ControlCopy
Freezing of Water
Drying of Clothes
Condensation of Water Vapours
Naphthalene Balls
Deposition
Deposition is the reverse of sublimation. In deposition, the gas directly converts directly into solid without turning into liquid first. For example, when it is very cold outside, frost (a thin layer of ice) begins to form on the glass windows or grass, especially during the night. This happens because water vapour in the air turns directly into ice, without turning into water first.
Not all materials change states at the same temperature. Different things change their state at different temperatures. For example, water boils at a higher temperature than some other liquids, like alcohol.

Soluble and Insoluble Substances
What happens when you add a teaspoon of salt to a glass of water? Can you see the salt and water separately? Or do they both mix together completely? When we add salt to the glass of water, at first we can see them separately. Gradually, it dissolves completely and we cannot see the salt separately anymore. But what happens when we add sand to water? Even after a lot of mixing, the sand and the water can be seen as different layers. Gradually, the sand settles at the bottom of the glass but still does not dissolve in it. This means that the sand does not dissolve in water.
Based on their ability to dissolve, substances can be classified as soluble or insoluble. Let us learn about them.
Salt is soluble in water.
ControlCopy
Soluble substances are things that can dissolve in a liquid, especially water. Salt and sugar are soluble substances.
Insoluble substances are things that do not dissolve in a liquid. No matter how much you stir, these substances will not mix with the liquid. Sand and chalk powder are insoluble substances.
Solution
When we dissolve a soluble substance in a liquid, we form a solution. The substance that is dissolved is called a solute. The substance in which the solute is dissolved is called a solvent. In a solution, the solute is evenly distributed in the solvent.
Did You Know?
Water is a universal solvent as most substances dissolve in water.
When we mix a spoon of salt in a glass of water, we get a salt solution. Here, salt is the solute and water is the solvent. But have you ever wondered where the salt goes when mixed with water? We have already learnt that liquid molecules are loosely packed. They have spaces between them. So, the salt molecules fit into these spaces.

Force
Force is a push or a pull applied on an object. We use force to do many things. Here are some effects of force:
• Force can move objects: When you kick a football, it moves.
• Force can stop moving objects: A fielder uses force to catch and stop a moving ball.
• Force can change the direction of moving objects: A batsman changes the ball’s direction by hitting it with his bat.
• Force can change the shape of objects: Pressing dough changes its shape. Similarly, when we squeeze a toothpaste tube, its shape changes.
ControlCopy
Discuss!
Discuss with your classmates two effects of force that you experience in your daily life.
Types of Forces
Forces are of many types, such as muscular force, gravitational force, magnetic force and frictional force. Let us now learn about them.
Muscular Force
Muscular force is the force applied by the muscles of our body. Whenever we move our body parts, like our arms or legs, we use muscular force. For example, a rickshaw puller uses muscular force to pedal and move the rickshaw forward. We walk, run, jump, bend and lift using our muscular force. Animals like bulls and horses also use muscular force to pull carts.
Gravitational Force
Rickshaw puller uses muscular force to pull the rickshaw.
Have you ever wondered why a ball thrown upwards comes back to us? It is because of gravity. Gravitational force, or gravity, is the force that pulls everything towards the
Earth. Every object on Earth experiences this force. It is for the same reason that fruits fall to the ground instead of floating away when falling from a tree. Gravitational force also attracts all objects in space towards each other.
Gravitational force does not act only on falling objects. It acts on everything present on Earth, including you and everything around you, keeping them grounded. Error Alert!
Magnetic Force
gravity.
Discuss!
What would happen if there was no gravity on Earth?
Magnetic force is the force exerted by a magnet on another magnet or on magnetic materials like iron. For example, when you bring a magnet close to iron nails, the nails stick to the magnet because of magnetic force.
Frictional Force
Friction is the force that opposes movement between two surfaces in contact. It slows down moving objects and finally stops them. For example, when you slide a toy car on the floor, it gradually slows down and then stops because of the friction between the car’s wheels and the floor.
Frictional force is important in our daily lives. It helps us to walk and run. We can hold things due to friction. If there were no friction, a moving object would never stop by itself.
Do and Learn
ControlCopy
Choose any sport like football, cricket or basketball and note how force helps you play them. For example, kicking a ball moves it (muscular force), and gravity pulls the ball down when it is in the air (gravitational force).
Try this: kick a ball and watch how it moves, changes direction or stops when someone catches it. Then, discuss with your classmates how forces like friction, gravity and muscular force are at play during the game. You’ll discover that sports are a fun way to see forces in action.

A moving toy car stops after some time.
Investigate and Discover
Aim: To prove that rough surfaces cause more friction than smooth surfaces.
Materials Needed: One ball, chalk / marker, a measuring tape or a ruler
Method:
Step 1: Mark a starting line on your classroom floor. Roll the ball on the floor by lightly pushing it forward. Use the measuring tape to note the distance it covers on the floor before it stops.
Step 2: Now, roll the ball again but this time on the grass in your school field, using equal amount of force. Compare the distance covered by the ball on the floor and on the grass.
Findings: The ball rolls farther on the classroom floor than on the grassy field.
Conclusion: Smooth surfaces have less friction, making it easier for objects to move over them. Rough surfaces like grass cause more friction, making it harder for objects to move over them.

Pause and Answer Energy
Energy is the ability to do work. There are different forms of energy. We also use fuels such as coal, petrol, diesel, natural gas, kerosene and wood to get energy.
Forms of Energy
Energy is exists in many forms. Let us learn more about them.
Solar Energy
Solar energy comes from the Sun, which is the ultimate source of energy on Earth. It gives us heat and light. Plants use sunlight to make food, which we eat to get energy. We also use the Sun’s energy directly in solar cookers and solar heaters. Solar panels are used to generate electricity from solar energy.
Did You Know?
Many villages in India use electric stoves that run on electricity generated by solar energy, thereby reducing the need for firewood and promoting the use of clean energy.
Wind Energy
Fast-moving winds can be used to generate energy in the form of electricity. They are used to spins the blades of a windmill, which then turns machines called turbines to produce electricity.
Hydro Energy
Fast-moving water in rivers contains a lot of energy. To use this energy, dams are built across rivers. These dams store water, which is then released from a height, directing it into turbines. The turbines spin due to the water's force, generating electricity. This type of energy, gained from the flow of water or from water falling from a height, is known as water energy or hydro energy.
Electric Energy
Electric energy is either produced in power plants by burning coal and natural gas, or through solar, wind and hydro energy. It is used to run electrical appliances and devices such as fans, lights, TVs and computers.
Heat Energy
We get heat energy by burning fuels. Coal, petroleum and wood are examples of fuels. This energy is then used to run vehicles, cook food, and to generate electricity.
Energy can neither be created nor destroyed. It can only be changed from one form to another. For example, in electric bulbs, electric energy is converted into light energy. In electric irons, electric energy is converted into heat energy.

Do these things make our work easier?
What is a Machine?
Can you cut a piece of wood with your hands? Can you open the sealed lid of a glass bottle without a bottle opener? The answer to these questions is no. We need different machines to do these tasks. We need a saw to cut wood and a bottle opener to open a bottle.
A simple machine is a device that makes our work simple, easier and faster.
Importance of Machines
Have you ever observed an adult chop vegetables? They may use a knife or a chopper. These are machines. They chop the vegetables more easily by using force.
Simple machines can be used to change the direction of the force or make the force stronger. They also make our work easier in the following ways.
• Machines reduce the amount of force we need to apply to complete a task.
• Machines help us perform tasks more quickly.
Remember!
A force is a pull or push applied on an object.
• Machines allow us to complete tasks more efficiently, saving our time and energy.
Types of Machines
There are six types of simple machines. Let us learn about them, one by one.
ControlCopy
Inclined Plane
An inclined plane is a surface whose one end is raised to some angle while the other end stays on the ground. It requires a lot of effort to lift something straight. But it is easier to push or roll it up an inclined plane. This makes tasks like loading or unloading heavy goods from trucks much easier. Some examples of inclined planes are ramps, slides and sloped roads.
Think and Tell
Can you think of two places where an inclined plane helps?
1. Inclined plane 2. Wedge 3. Wheel and axle
4. Screw
5. Pulley 6. Levers
Inclined Plane
Loading heavy goods on a truck.
Wheel and Axle
This simple machine has a circular part called the wheel attached to a smaller rod called an axle. The axle is attached to the centre of the wheel. When the axle moves, the wheel turns around it. We can easily move heavy objects using this arrangement. Some examples of wheel and axle are the steering wheel of a car, bicycle pedals and roller skates.
Pulley
A pulley is a simple machine made up of a grooved wheel with a rope around it. The heavy objects are attached at one end of the rope, while we pull the other end of the rope. It is used to lift or lower heavy objects like drawing water from wells, hoisting flags, and pulling window blinds up.
Wedge
A wedge is a simple machine made up of two inclined planes joined back-to-back, forming a sharp edge. It is used to cut or split objects. Some common examples of wedges are knives, axes and nails.
Screw
A screw is an inclined plane wrapped around a cylinder. It is used to hold objects tightly together. Some examples of screws are bottle caps, jackscrews, nuts and bolts.

Lever
A lever is a straight rod that rests on a fixed point and can be turned around that point. That fixed point is called the fulcrum. The force applied on a lever is called effort. The object that is moved by a lever is called the load. For example, a metal spoon used to open a tin lid acts as a lever. Some other examples of levers are scissors, bottle openers, pliers, tongs and a see-saw.
Look around and observe what devices and tools are being used in your daily life. For example, your mother using a knife to cut vegetables is an example of a lever being used. Write the type of simple machines for each of the devices.

Making Machines Efficient
Machines help us do work more easily and quickly. But, to get the best results, it is important to keep them working efficiently. Here are some simple ways to make machines more efficient:
• Cleaning: Remove dust and dirt from machines to keep them running smoothly.
• Lubricating: Apply oil or grease to moving parts to reduce friction and wear-and-tear.
• Tightening: Check and tighten any loose bolts or screws to keep the parts of a machine in place.
• Follow Instructions: Always read and follow the instructions for using a machine.
• Avoid Overloading: do not use a machine to do more work than it is designed for. For example, do not carry too much weight in a wheelbarrow.
• Use the Right Tool: Make sure to use the correct machine or tool for the job. For example, use a knife to cut vegetables and not a screwdriver.
By taking care of machines and using them properly, we can ensure they help us do our work efficiently and last longer. This not only saves time and effort but also helps in conserving resources.

One Sunday, Aisha decided to bake a cake.
“I want to make the tastiest cake ever!” Aisha exclaimed. She mixed one cup each of flour, sugar, baking powder and butter.
Her mom smiled and said, “Aisha, we need to measure our ingredients correctly. Let me help you.”
Aisha was puzzled—why did it matter? Mom explained that measuring the ingredients carefully helps the cake rise and be fluffy. With a measuring cup in hand, Aisha learned that the secret to a great cake is all about the right measurements.
Importance of Measurement
Have you ever noticed what a fruit seller does when you go to buy some fruits? They measure the weight of fruits using a weighing balance. Similarly, the milkman measures the quantity of milk before selling it. You wake up at a fixed time to reach the school on time. We measure so many things in our daily life. Measurement plays an important part in our everyday lives.
A vegetable vendor weighing tomatoes.
Standard Units
In ancient times, different body parts were used to measure different things. We know different persons have different sizes of the same body parts. Therefore, the older units gave different measurements for the same things and could not be used reliably.
To avoid the difference in the measurements, standard units were introduced. These units give the same results for all the measurements. The value of the standard unit is fixed and does not vary from person to person.
The standard unit for measuring length is metre (m), for measuring weight is kilogram (kg) and for measuring volume or capacity is litre (L).
Did You Know?
The metric system is a system of measurement that measures length in metres, weight in grams and volume in litres.
Remember!
A unit is a fixed quantity that is used as a standard of measurement.

Measurement and Estimation
Measurement refers to the action of measuring the amount, duration and size of something. But sometimes, we just guess the value of a measurement, without actually measuring it. This thoughtful guess about the value of something is called estimation. By estimating, we only get a rough idea about a measurement.
Estimation is useful in many ways in our daily lives. Have you ever seen your mother cooking food in the kitchen? Does she use any measuring instrument while adding salt to the food? No, right! She adds salt by estimation only. On the other hand, if you were experimenting in the science lab and added a chemical with estimation only, do you think you will get the correct results? No. While experimenting, we need to have exact measurements of the materials used. Otherwise, we will get incorrect results.
Think and Tell
Can you give any two examples where you estimate measurement in your daily life?
Estimating the amount of spices required
reliably: doing something in a way that can be trusted to work well every time thoughtful guess: a guess made on a topic after having studied it very well
Measuring Time
Time is a measure of the duration of an event. It is used to determine the beginning and ending of something. It also tells us for how long an event occurs.
Units of Time
The basic unit of measuring time is seconds. Some other units of time are minutes, hours, days, weeks, months and years. The unit of time changes with the type of activity involved. For example, if you are going out for a film, you will measure time in hours. If you are participating in a 100-metre race with your friends, you will measure time in minutes.
Instruments to Measure Time
Think and Tell
Can you think of some more examples where you measure time in your daily life?
ControlCopy
We use clocks to measure time. A clock has two major hands—an hour hand and a minute hand. Some clocks have a second hand as well. The hour hand is shorter than the minute hand.
It takes the second hand 1 minute to complete one round of the clock. Similarly, it takes the minute hand 1 hour to complete one round of the clock. Lastly, it takes the hour hand half a day to complete one round of the clock.
A clock has the numbers 1 to 12 on it. These numbers tell us the hours of the day. When an hour is complete, the hour hand moves from one number to the next. The clock shows a total of 12 hours at a time. The hour hands needs to go around the clock twice to show one day.
A clock also has five little dashes (') between every two numbers. These dashes represent minutes or seconds, depending on which hand is on them. There are 60 dashes in total to show that there are 60 seconds in a minute, and 60 minutes in an hour.
However, just by looking at the clock we cannot say if it is morning or evening. To determine that, we use a.m. and p.m. along with the time value. The period from midnight till noon is indicated by adding a.m. with the time. The period from noon till midnight is represented by adding p.m. with the time. For example, 11 a.m. (in the morning) and 11 p.m. (at night).
Analog Clock
Make a list of some activities that you do daily like having breakfast, lunch and dinner, going to school, doing your homework, playing and sleeping. Now, mention the time of each activity. Make sure to write a.m. or p.m. with the time value.
There are two major types of clocks—analog and digital. A digital clock shows numbers to indicate the time. It does not have hour and minute hands. Sometimes, we use a stopwatch to measure very short time intervals. It is a hand-held watch with a start and a stop button.
Did You Know?
In earlier times, a sundial was used to measure time. A sundial had two parts, a circular dial with 12 marks, and a stick in the centre.

Measuring Temperature
Have you ever touched something cold, like ice or a glass of cold water? When you touch it, you feel the cold on your skin. Now, think about touching something hot, like a hot pan on the stove. The moment you touch it, your skin feels the heat, and you quickly pull away. These experiences help us understand temperature, which measures how hot or cold something is.
Thermometer
A thermometer is a device that is used to measure temperature. A thermometer has three main parts: a glass outer tube, a thin inner tube, and a small bulb filled with a liquid. There are markings on the inside to measure how hot or cold something is.
Digital Clock Stopwatch
When we use a thermometer, the liquid in the bulb moves up the tube to a specific marking, which tells us the temperature of the particular thing.
Units of Measuring Temperature
We measure the temperature in different units like degrees Celsius (˚C) and degrees Fahrenheit (˚F). Usually, we use degrees Celsius to measure the temperature of objects. We usually measure the temperature of animals and humans in degree Fahrenheit.
Investigate and Discover
Aim: To prove that a thermometer can measure different temperatures accurately
Materials Needed: Thermometer (digital or mercury), a glass of hot water, a glass of cold water, a glass of water in room temperature, a notepad and a pencil

The Solar System The Earth Satellites
Let us recite the poem together!
The Sun shines bright with golden rays, Warming Earth throughout the days. Earth spins round, both night and day, Bringing light in a wondrous way. Life on Earth, the Sun sustains, Together they, in harmony, remain.
Introduction
We all live on the planet Earth. The Earth revolves around the Sun. Likewise, there are seven more planets that move around the Sun. Do you think people live on these planets as well? What is the position of planets around the Sun? Let us find out. The natural objects that appear in the sky are called celestial or heavenly bodies. Some examples of celestial bodies are the Sun, the stars and the Moon. Earth
The Solar System
The Sun and the planets, and other heavenly bodies that revolve around them, are together called the solar system. The Sun is at the centre of the solar system. All the planets and the other celestial bodies revolve around it in an elliptical path called an orbit.
Sun
The Sun is a star. Stars are celestial bodies that are huge balls of gases and have their own heat and light. So, the Sun also releases heat and light. The Sun is the nearest star to the Earth. This is why it looks bigger than other stars.
Remember!
The Sun is the ultimate source of energy on the Earth.
Planets
Planets are the celestial bodies that move around the Sun. All planets move in their respective orbits around the Sun. The gravitational force of the Sun keeps the planets in their place in the solar system. They do not have their own light; instead, they reflect the Sun’s light.

The Earth
We all live on the surface of the Earth. But have you ever wondered what is the Earth made up of? Let us learn about this in detail.
Layers of Earth
ControlCopy
The Earth is made up of three main layers—crust, mantle and core.
Crust/Surface: It is the outermost layer of the Earth. It forms the surface on which we live. It is hard and cool.
Mantle: It is present between the crust and the core. It is made up of rocks, minerals and metals. This is a solid layer of the Earth.
Core: It is the innermost layer of the Earth. It is very hot. It is made of metals, minerals and gases. The core is further divided into two parts—the outer core and the inner core. The outer core is liquid. The inner core is solid.
Movement of Earth
Imagine you are riding on a merry-go-round at the playground. As it turns around, you see different parts of the playground because it moves in a circle. This is how a merry-go-round moves around a central point.
The Earth is also like a huge merry-go-round. It has an imaginary line that passes through its centre between the North and South poles. This imaginary line is called an axis. The axis is not a straight
imaginary: unreal

line. It is slightly tilted. The North Pole is the point at the top of the axis. The South Pole is the point at the bottom of the axis.
The equator is an imaginary line that divides the Earth into two halves. The upper half is the Northern Hemisphere. The lower half is the Southern Hemisphere.
The Earth performs two types of movements, rotation and revolution. Let us learn about them.
Rotation
Have you ever seen a top spinning on the ground? It spins on its axis. Similarly, the Earth also moves around its axis. This movement is called rotation. The Earth takes 24 hours to complete one rotation.
The rotation of the Earth on its axis causes the formation of day and night. During rotation, the part of the Earth that faces the Sun experiences day. The other part of the Earth that does not receive sunlight experiences night.
Revolution
It is the movement of the Earth in its orbit around the Sun. When the Earth completes one round along its orbit, it is called a revolution. The time taken to complete one revolution is one year.
The Earth’s revolution causes different seasons. You know that the Earth’s axis is tilted. This
ControlCopy
Formation of Day and Night
Similarity Between Spinning Top and Earth
makes one pole of the Earth closer to the Sun at a particular time of the year. Thus, that hemisphere receives more sunlight and experiences summer. At the same time, the other hemisphere that is tilted away from the Sun experiences the winter season.
Revolution changes the position of the poles tilted towards the Sun. For about six months in a year, the North Pole is tilted towards the Sun while for the rest of the year, the South Pole is tilted towards the Sun. This cycle of tilt and revolution causes the seasons to change throughout the year.
ControlCopy
Here, it is important to note that the equator always receives direct sunrays. So, it always remains hot. On the other hand, the North and South poles always remain cold.
Investigate and Discover
Aim: To study the formation of day and night.
Materials Needed: A clay ball (representing the Earth), a wooden stick and a torch
Method:
Step 1: Take the clay ball and insert a wooden stick in it. Make sure the stick is slightly tilted. This will represent the Earth’s axis.
Step 2: Throw light on the clay ball using a torch. Observe what happens.
Findings: The part of the ball that receives direct torchlight indicates day. On the other hand, the opposite dark part represents night.
Conclusion: The Earth’s rotation is responsible for the formation of days and nights.

Satellites
Do you know that the Moon revolves around the Earth? A heavenly body that revolves around a planet is called a satellite.
Therefore, the Moon is the natural satellite of the Earth. The Moon does not have air or water to support life. The surface of the Moon that we see from the Earth is called its face. The surface of the Moon is not smooth. Instead, has craters on it.
ControlCopy
The Earth is also surrounded by several man-made objects known as artificial satellites, which orbit the planet. These satellites are launched into space using rockets. The first artificial satellite sent into space by humans was Sputnik 1. Artificial satellites play important roles, such as weather forecasting, providing communication services, and studying the solar system and the universe.
Did You Know?
The Moon appears as a beautiful shiny object from the Earth. However, it does not have its own light. The Moon shines when it reflects the Sun’s light.

PROJECT 2
Exploring Inclined Planes
Objective: Students will explore how the slope of an inclined plane affects the speed of an object that is moving down the inclined plane.
Materials Needed:
Wooden plank or piece of cardboard (2–3 feet long), stack of books (to create different slopes), toy car or small rolling object, ruler or measuring tape, stopwatch, notebook and pencil (to record results)
Step 1: Learn about Simple Machines
Revise about the different types of simple machines given in the textbook. Focus on how an inclined plane makes our work easier.
Step 2: Create the Inclined Plane
Place one end of the wooden plank or cardboard on a stack of 2–3 books to create a low slope. Measure the height of the slope from the ground using the ruler or measuring tape. Record this height in your notebook.
Step 3: Measure Speed Down the Inclined Plane
Place the toy car at the top of the slope and let it roll down. Use the stopwatch to measure the time it takes for the car to reach the bottom of the slope. Record the time in seconds. Repeat this step three times to get an average time for the low slope. Record all results.
Step 4: Repeat for Different Slopes
Increase the height of the inclined plane by adding more books (4–5 books for a medium slope, 6–7 books for a high slope). Repeat Step 3 for each new slope, measuring the time taken for the car to reach the bottom three times and calculating the average time.
Step 5: Compare the Results
Create a table to compare the height of the slope and the average time taken for the car to reach the bottom.
ControlCopy
Project Output: You have learnt that the time taken for the car to reach the bottom, changes with different slopes. The higher slopes result in shorter times, meaning the car moves faster. Present your findings to your class.
Final Outcome: This hands-on project will help you understand how an inclined plane works and how it reduces human effort to make tasks easier by allowing objects to move smoothly and quickly.

Solar Energy
In India, solar energy has made a big difference by providing many real-life benefits. For example, in small villages, solar panels on rooftops provide enough energy to light up homes, run fans and charge mobile phones. Large solar parks in Gujarat and Rajasthan produce a lot of electricity for the country. Solar energy works by capturing sunlight with panels and turning it into electricity. This helps reduce pollution and cuts down on electricity bills. The Indian government’s National Solar Mission also supports putting solar panels on government buildings and schools, encouraging more people to use this clean energy source. By using solar energy, we can help protect the environment and make sure there is enough power for everyone.

Need and Sources of Water
Water is essential for all life. We need water for drinking, cooking, cleaning, washing and bathing. Animals and birds also require water to survive. Water is crucial for growing crops too.
Remember!
Although three-fourths of the Earth’s surface is covered with water, most of it comes from seas and oceans. Since this water is salty, it cannot be used for drinking.
Growing crops Bathing Washing Fishing
Farmers depend on rains for agriculture. Rainwater that seeps into the ground and gets stored below the Earth’s surface is called groundwater. Rainwater also collects in ponds and lakes.
Think and Tell
In what ways do you use water every day?
Means of Irrigation
Farmers need water to grow their crops. A sufficient and timely supply of water is essential for growing crops. This is done through irrigation. Irrigation is a method of providing water to crops in large fields.
Some methods of irrigation in India are:
River Water: Rivers are one of the main sources of irrigation in India. Some rivers, like the Indus and the Ganga, have water all year round and are called perennial rivers. Other rivers, such as the Mahanadi, Godavari, Krishna and Kaveri, fill up only during the monsoon season and are called seasonal rivers.
Wells and Tube Wells: Wells are dug in areas where there is enough groundwater. When pumps are used to extract water for irrigation, this system is called a tube well. These pumps can be powered by electricity, hand or diesel. This method is commonly used in India to draw water from deep underground for irrigation.
seeps: to flow or leak slowly through small openings or pores
Did You Know?
The Brahmaputra River in India is unique for its seasonal changes. During the monsoon, it rises to ten times its size during the dry season.

Irrigation Canals: Irrigation canals are human-made channels used in areas where water is limited. These canals carry water from rivers to various parts of the country. For example, the Indira Gandhi Canal in Rajasthan carries water from the Sutlej and Beas Rivers to different parts of Rajasthan.
Tanks and Ponds: Tanks and ponds are used in areas where it is difficult to dig wells. They are used during the dry season when there is a scarcity of water. Some water from these tanks seeps into the ground, which helps to refill the groundwater.
Dams: Dams are built on rivers to create large reservoirs for storing water. These reservoirs fill up during the monsoon and help to prevent flooding. The stored water can then be used for irrigation when there is not enough water available. Dams also generate electricity from the flowing water, known as hydroelectricity. Some important dams in India are:
• Bhakra Nangal Dam on the Sutlej River in Himachal Pradesh
• Nagarjuna Sagar Dam on the Krishna River in Andhra Pradesh and Telangana
• Farakka Barrage on the Ganga River in West Bengal
• Hirakud Dam on the Mahanadi River in Odisha
• Mettur Dam on the Kaveri River in Tamil Nadu

Shortage of Water
India faces significant water shortages in many states and villages. Some of the main reasons for this are:
• Less Rainfall: When it does not rain enough, there is insufficient water in rivers and lakes.
• Wasting Water: People sometimes leave taps running, thereby wasting water.
• Pollution: Dirty water from factories can make clean water unsafe for use.
• Cutting Trees: Trees help to bring rain, thus, cutting them down can reduce rainfall and water supply.
• Rapid population growth: Population growth has increased water demand, putting pressure on the already limited water resources in cities.

Rainwater Harvesting
Water is essential for all life on Earth, so it is important that we conserve it. One effective way to save rainwater is through rainwater harvesting. This involves collecting rainwater from rooftops and the ground and directing it into a deep pit or well that has been dug into the Earth. This process helps to increase groundwater levels and also prevent waterlogging and soil erosion.
Rainwater can be collected in tanks and stored for later use, especially during dry seasons. The collected rainwater can be used for irrigation, gardening, washing and even drinking after it has been properly filtered.
conserve: to avoid wasting something and collect it for future use erosion: the removal of the top layer of soil by natural forces, such as wind, water, or ice or through human activities

Coal is an important mineral fuel. It forms from the remains of dead plants and animals that lived many years ago. Coal is a non-renewable resource. Some of the most important coal mines in India are located in Singrauli, Madhya Pradesh; Bokaro, Dhanbad and Jharia in Jharkhand; and Raniganj in West Bengal.
Crude oil, or petroleum, is a thick, dark liquid found deep underground. It is formed over millions of years from the remains of tiny plants and animals. When these living things died, they sank to the bottom of the ocean. Over time, heat and pressure from the Earth’s layers transformed them into oil.
Petroleum is very important because it is used to make many things we use every day, like plastics and lubricants. To extract crude oil, people drill deep into the Earth, using oil wells. These wells bring the oil to the surface.
Did You Know?
Coal is made up of a substance called carbon. This same substance is also found in diamonds.

An oil refinery
Once crude oil is collected, it goes to the oil refineries. At the refineries, crude oil is cleaned and processed to make useful products like petrol, diesel and kerosene.
In India, some well-known places where oil is found and refined include Assam (Digboi), Gujarat (Ankleshwar), Mumbai High (offshore in the Arabian Sea) and Rajasthan (Barmer). These locations are important for producing the oil we need for energy and various products.
Natural gas is found along side petroleum in oilfields. It is used to make
Compressed Natural Gas (CNG), which is a fuel for vehicles. CNG does not cause pollution, so it is used in several Indian states as fuel for public transport.

Cow dung is also used as a fuel to light fires for cooking in villages.
In India, many farmers practise mixed farming, which means they engage in both agriculture and animal rearing on the same farm.
Green Revolution
The Green Revolution was a big change in farming that started in the 1960s to increase food production. It introduced high-yield seeds, fertilisers, irrigation methods and big machines that helped with ploughing fields and harvesting. All of these helped farmers to produce crops like wheat and rice in large quantities.

An industry is a group of businesses that makes specific goods or provides specific services. For example, the car manufacturing industry makes cars, the clothing industry makes clothes, etc.
Remember!
Once goods are made in factories, wholesalers buy them from the factories and sell them to local shopkeepers. These shopkeepers then sell the goods to us.
Location of an Industry
The location of an industry depends on many factors, such as:
• Capital, or money: Without money, industries cannot be set up or run.
• Availability of raw materials: Industries are located near places where the required raw materials can be found easily. For example, steel industries are set up in areas where iron is found. Textile industries are set up in areas where cotton is grown.
• Energy supply: Industries need power to run machines, so they are located in places where electricity is easily available.
• Transportation: Industries need to transport their raw materials and send out finished goods, so they are usually set up near roads, railways or ports.
• Workers: Industries need workers, so they are often located where it is easy to find workers.

Types of Industries
There are different types of industries. Those that use crops as raw materials are called agro-based industries, such as the cotton industry, jute industry and sugarcane industry.
Industries that use minerals like iron, copper and bauxite are called mineral-based industries. Examples are the steel industry, automobile industry and oil industry.
Industries can also be divided into three types based on their size. There are large-scale industries, small-scale industries and cottage industries. Let us learn about each one.
Large-scale Industries
Large-scale industries produce a large number of goods using huge machines and many workers. These industries need a lot of space, money and raw materials. They often produce items that are used all over the country or even the world, like cars, steel and electronics. They are usually located near facilities like mines or ports. Large-scale industries are important because they create many jobs and produce goods that people use every day.

Small-scale Industries
Small-scale industries are businesses that are much smaller than large-scale factories. They usually have fewer workers and smaller machines, and they produce goods in smaller quantities. These industries often use local materials and can be set up in villages or small towns. Because they are smaller, they need less money to start and run.
For example, the tailoring industry that makes clothes is a small-scale industry. These industries are important because they provide jobs and help the local economy grow.
Cottage Industries
Cottage industries are small businesses where people make things at home or in small workshops. These industries are usually family-run and don’t need big machines or a lot of money to start. The products are often handmade, using traditional methods that have been passed down through generations.
Examples are, pottery, bamboo products, handicrafts and candle-making.
Cottage industries mostly use local materials and skills. Hence they are better for the environment and also create jobs for local communities. They also keep the traditional crafts alive.

There are two types of land transport: roadways and railways.
Roadways
India has a wide network of roads that connects cities, towns and villages. It is also easier to build roads compared to laying railway tracks or building airports or ports. Roads are useful because they connect our homes directly to markets and other places.
Nowadays, electric cars and buses are also used on Indian roads. They have rechargeable electric motors and do not use petrol or diesel to run. Thus, they are also good for the environment and do not cause air pollution.
There are many types of roads in India. Two main types are national highways and state highways.
National highways connect states with each other across India. State highways link important cities, towns and districts within the state. They also connect National Highways or state highways of the neighbouring states.
The national highways are constructed and maintained by the National Highways Authority of India (NHAI) and the state highways are constructed and managed by the Public Works Department of each state.
Think and Tell
The Golden Quadrilateral is a national highway that connects four major metro cities: Delhi, Kolkata, Mumbai and Chennai. Along the route it connects many major industrial, agricultural and cultural cities of India. It is 5846 kms long.
Do and Learn
Make a list of the national highways and state highways that you have in your city or state.
Railways
Did You Know?
The first railway line in India began in 1853 between Mumbai and Thane.
Railways in India transport thousands of passengers to work, vacation and business every day. They also transport several tonnes of goods from places where industries are located to the markets across India, thus helping in economic activities and development. Since Indian railways are connected to our lives in so many ways, they are referred to as ‘the lifelines of the nation’.
Compared to roadways, railways are faster and more comfortable when travelling over long distances.
India has different types of trains that serve different purposes. They are passenger trains, superfast trains and goods trains. Passenger trains focus on the comfort and basic facilities for the passengers. Superfast and express trains have limited halts on the route, so passengers can reach their destination faster. Today, the Vande Bharat Express is one of the fastest passenger trains in India. Goods trains transport only goods over long distances.
Goods train
Some trains connect different places within the city and some neighbouring areas. They are local trains and metros. For example, local trains in Mumbai connect several locations within the city, and metro trains do the same in Kolkata, Delhi and Chennai. Metro trains work underground and underwater as well. For example, a part of the Kolkata metro runs underwater and a part of the Delhi metro runs underground.
Think and Tell
What is the name of the railway station in your city or town?

1. Metro trains run within the city.
2. Local trains run between two states.
3. National Highways are maintained by the Public Works Department.
4. State highways link important cities, towns and districts within the state.
Water Transport
Water transport helps to move large amounts of goods over long distances, and it is often cheaper than other types of transport.
In modern times, we have container ships that carry cargo, oil tanker ships that carry petroleum and cruise ships that carry people. Cruise ships are large ships that carry passengers and have many modern facilities like cinema halls, lifts, rooms, restaurants, etc.
India has ports on the west and the east coast. Some major ports on the west coast are Kandla Port, Jawaharlal Nehru Port, Kochi Port and Mormugao Port.
Inland waterway in India
Air Transport
Some major ports on the east coast are Chennai Port, Paradip Port, Haldia Port and Visakhapatnam Port.
In India, there are many rivers, canals and lakes that are navigable. They are called inland waterways. For example, the Ganga and the Brahmaputra river are two main inland waterways in India.
Air transport is the fastest means of transport. It is often more expensive than other means. It makes it convenient to reach mountains and hilly regions that are otherwise difficult to reach using roadways or railways. During natural disasters such as floods

Meaning and Types of Communication
Communication is the way in which we share or exchange our ideas, thoughts, feelings and information with others. There are different methods through which people communicate with each other, for example, they may call each other on the phone or write letters. There are many types of communication, but in this chapter, we will learn about the two main types—personal communication and mass communication.
Communication between two individuals is called personal communication. The means of personal communication include letters, telephones, mobile phones, etc.
Communication between a large number of people is called mass communication. The means of mass communication are television, radio, etc.
Let us learn about them in detail.
Methods of Personal Communication
The Postal Service
The Indian Postal Service is the largest in the world and is known as India Post. We can send postcards, letters and parcels anywhere using postal services. We can use their services to send letters and parcels to different places in India and outside India. Money orders are also sent through postal services. A postman collecting letters from a postbox.

With the help of your parents, post this letter to your cousin/friend. Remember to write their full address and pin code before posting it.
Telephone
The telephone is an important means of communication. We can talk to anyone living in India or anywhere in the world using a telephone. The STD (Subscriber Trunk Dialling) facility helps us connect across different cities within our country. On the other hand, the ISD (International Subscriber Dialling) facility helps us to connect with people living in other countries.
Cell Phone
Communication became easy and quick with the introduction of cell phones. They are one of the most convenient way of communication, as they can easily be carried with us wherever we go. They also provide us with the Short Messaging Service (SMS)
money order: a special document which we can send to someone through post and they can get money in exchange for it convenient: easy to use
to send text messages. The modern version of cell phones or mobile phones are the smartphones. Smartphones are more advanced than cell phones and we can use them to access the internet, watch films, listen to songs, send emails, etc.
Email and Fax
Email or electronic mail is a fast way of sending electronic messages. Internet services are used to send emails with the help of computers and smartphones. Another way of sending written messages or images instantly is through the fax system. Here, the telephones are connected to fax machines. Thus, a document sent over the telephone is called a fax.
Methods of Mass Communication

Share any two ways in which smartphones can be used for education.
When messages or information need to be spread to a large number of people, then methods like newspapers, radio and television are used. Let us learn more about them.
Newspapers and Magazines
These are some of the most common forms of communication used to spread information to the masses. They help us know about events around the world. Newspapers and magazines are printed in different languages.
Radio
We can listen to global and national news along with different entertainment programmes on the radio. It is specially helpful for people who cannot read, as well as those who have difficulty seeing. We can also listen to educational programmes on the radio.
Television
We can watch and listen to major events, natural disasters, films, songs, etc., on a television.
masses: a large number of people global: related to the whole world

Different cultural events such as the Republic Day celebration and important sports events, such as football and cricket World Cup matches can all be seen live on television. This is possible due to satellites.
Satellites
Think and Tell
Why do you think radio became an important means of communication for people before the invention of the television?
Satellites are objects launched into space that revolve around the Earth. They help with communication, weather updates, etc. Satellites send and receive signals from mobile phones, smartphones, TVs and computers over long distances. This helps in connecting people worldwide.
Social Media
Social media is a way to connect and share ideas with others using the internet. Some examples of social media platforms are Instagram, Meta and YouTube. They allow people to post pictures, videos and messages. Friends and family can comment on, like, and share things with each other on these platforms.
One must be careful and responsible when using social media. We should never share our personal information and pictures with strangers who try to talk to us online.

Look at the images given below. Can you identify what is shown in them?
Teacher: Just as we have teachers and a principal to make rules and keep everything running smoothly at school, there are people who do the same for our country. They are part of the government.
Maya: So, does the government help to manage the country?
Teacher: Exactly! The government makes rules, solves problems and takes care of the people.
The government is a group of people who runs the country, makes laws and ensures everyone follows them to keep things organised. The people of India choose their government through elections. All Indian citizens who are 18 years of age or above can vote in these elections.
In India, there are three levels of government—the central government, state government and local governments. In this chapter, we will learn more about these governments.
Central Government
The President of India is also the Supreme Commander of the Indian Armed Forces. Did You Know?
The central government takes care of the whole country. It makes important decisions for everyone, such as building big highways, managing the army and printing money. For example, the central government decides what rules everyone in India should follow, regardless where they live. It also helps in emergencies like floods or droughts across the country.
The central government has important people like the prime minister, president, vice president and cabinet ministers. The prime minister is the head of the central government and the president is the head of the country. They work together in a building called the Parliament, where they meet to discuss, make and pass new laws.
The Parliament has two parts—the Lok Sabha and the Rajya Sabha. These people help ensure the welfare of all people of the country.
The government has three pillars—the legislature, the executive and the judiciary.
Legislature: It makes the laws for the country.
Executive: It ensures the laws are followed and supports in administration of the country.
Discuss!
The government takes care of the country and the needs and safety of the people. How can you as children contribute to take care of our country?
Judiciary: It interprets laws and makes sure everyone receives justice.
State Government
The state government takes care of a particular state, like Maharashtra or Tamil Nadu. It makes decisions for the people living in that state. For example, the state government maintains roads, builds schools and manages hospitals in the state. Each state has its own government to look after its needs.
cabinet ministers: important ministers who form a team with the prime minister

The Parliament of India in New Delhi
The important people in the state government include the chief minister, the governor and other ministers. The chief minister is the head of the state government and the governor is the head of the state. They work together to solve problems and make rules for their state. These rules are discussed in the State Legislature, which functions like the Parliament for the central government. The State Legislature has two parts—the Legislative Assembly and the Legislative Council. Only a few states in India have a Legislative Council.

The local government takes care of villages, towns and cities. It looks after things like clean water, roads, garbage collection and streetlights in these areas. In villages, the local government is called the Gram Panchayat. It is led by the Sarpanch who helps make decisions for the village, like providing clean drinking water or building schools. In cities, the local government is called the Municipal Corporation. It maintains parks, roads and provides other civic amenities. The Municipal Council takes care of towns.

Unique Beaches
Beaches are stretches of narrow land spread across the edge of the sea or ocean. Beaches mostly have sand, pebbles or rocks and often have pretty shells. Let us read about some of the most unique beaches around the world.
The Pink Sand Beach
Location: Bahamas
This beach gets its pink shade from tiny organisms called foraminifera that live in the coral reefs. They have bright pink or red shells that are full of holes. When these creatures die, their shells end up on the beach and mix with the sand, giving it a pink colour.
Location: Australia
The Jervis Bay Beach
When it gets dark in Jervis Bay, the water sometimes starts to glow with a blue light. This is because of tiny creatures called dinoflagellates. When the water moves, it lights up the beach as if the water is full of tiny stars.
The Keramas Beach
Location: Bali, Indonesia
It is a popular black-sand beach in Bali made of volcanic sand mixed with rocks. It is a popular beach among surfers because of the waves that can be up to three metres high.
The Glass Beach
Location: Fort Bragg, California
This beach is covered with colourful pieces of glass spread over white sand. It is not a natural beach, as it used to be a garbage dumping site. These unique pebble-like glass pieces formed over the years, as glass items were shattered and were made smooth by the waves.
The Papakolea Beach
Location: Hawaii, USA
This beach has green sand made of a mineral called olivine, which came from the lava of the Big Island (where the beach is located). When the lava cooled off, it stayed on the beach, giving the beach its unique green colour. There are only three other green beaches in the world.
India also has many unique beaches. There is a magical hide-and-seek beach in India, which vanishes completely twice a day. Use the internet to find out about it.

Waste Management
Every year, the world produces about 200 crore tonnes of solid waste. This waste often ends up in landfills and waterbodies. Let us learn how to manage the waste we produce.
We can reduce waste by following the different ‘Rs’ of waste management.
Refuse items that cause waste. Reduce waste; carry your own bottle or bag. Reuse old things instead of buying new ones.
Paper and Cardboard
Paper is made of wood. Recycling 1000 kilograms of paper can save 17 fully grown trees!
Recycling is changing waste material into reusable material.
Repurpose things and turn old items into new useful ones. Recycle only when you cannot reuse or repair.
What can be recycled?
Plastic destroys the environment, as it does not decompose easily. But it can be recycled easily.
Metals are recycled more easily than plastic. Steel is the most recycled material in the world.
Glass is fully recyclable. It can be recycled many times without reducing the quality.
Electronics often contain harmful materials that can’t be recycled safely.
This contains waste that is toxic, reactive to heat or fire or can cause diseases.
This waste can easily be broken down naturally through composting, so it is not recycled.
We should use separate dustbins for different types of waste, such as recyclable and non-recyclable items. This promotes proper waste management.

Uses of Drones
Drones are flying gadgets that can zoom through the sky. Some drones have a built-in camera that is used to take pictures and record videos. Let us learn more about drones and their uses.
Drone
A drone is a small aircraft that can be controlled by a person using a remote control or a computer. Drones are also known as Unmanned Aerial Vehicles (UAVs). They are named so because they are flown without a pilot or crew.
Is a Drone a Plane?
While both drones and planes are flown, yet they are very different in the way they are operated.
• A plane is flown by a pilot whereas a drone is flown by a person on the ground.
• Drones are limited to a certain range while planes can cover very long distances.
• Drones fly at lower heights compared to planes.
Uses of Drones
Media and Entertainment
Drones are used for capturing aerial shots for films, TV shows and sports matches.
Delivery
They are used by organisations to deliver medicines and goods during a natural disaster.
Agriculture
They are used by farmers to monitor the health of their crops.
Environment
They are used for monitoring air quality and pollution in water bodies.
Drones are not just high-tech gadgets. They are powerful tools that help to monitor animals in the forests. They also help to maintain the count of endangered species. They have empowered us to protect our environment in a better way.

Birthday Celebrations Around the World
Usually, we are excited about our birthdays. Did you know that birthdays are celebrated in different ways across cultures? Let us find out how birthdays are celebrated in different countries.
In Latin-America, girls celebrate their quinceañera when they turn 15 years old. This celebration marks a girl’s transition from girlhood to womanhood. The quinceañera receives many gifts and it’s customary for her to share the first dance with her father.
In the Chinese culture, the Zhuazhou is held when the child turns one year old. The parents put various objects in front of the child. These objects symbolise career choices or personality traits. The child’s choice is used to forecast their future. Generally, family and friends cook noodles to celebrate their child’s Zhuazhou.
In Australia, people celebrate children’s birthdays with ‘fairy bread’ instead of cake. White bread, butter and colourful sprinkles are the basic ingredients of fairy bread.
The Russians celebrate their children’s birthdays by giving gifts to every child invited to the birthday party. Adults hang gifts from a clothesline, and each child gets to pull one down and take it home with them.
The Vietnamese people do not celebrate each individual’s birthdays. Instead, on the Vietnamese New Year, everyone celebrates turning another year older, together.
In Canada, the birthday girls or boys have their noses coated with butter. It is believed that it wards off bad luck for the next year.
In Spain, people pull the ears of the person celebrating their birthday, once for every year of their age and finally one good pull for good luck and a long life.
Are there any special rituals that you follow when celebrating your birthday? Discuss these in class.

Vocational Skills
Vocational skills are skills that help people get a job and excel in their professions. Let us learn more about vocational skills.
Vocational skills are practical and hands-on skills that prepare people for a skilled craft. These skills are needed to do specific jobs. Some examples of vocational skills are: carpentry, electrical work and plumbing. The learning of vocational skills is also called vocational education.
A vocational school is a type of school that focuses on providing vocational training to its students. These schools are also called trade schools or vocational colleges.
There are some organisations in India that focus on vocational training.
The All-India Council for Technical Education was set up in 1945 to promote technical education in India. It works to ensure proper planning and development of a technical education system throughout the country.
The National Skill Development Corporation was set up by the ministry of finance in 2008. Its main focus is to promote skill development among Indian youth. It provides financial support to new companies. It also supports efforts by companies to introduce vocational training. Its aim is to ensure that the development of skills is not hindered by a lack of financial support.
The Skill India Mission is recognised by the government of India. It provides both short-term and long-term training programmes in different vocational skills. Its goal is to make it easier for Indian youth to find jobs and provide them with the skills and knowledge needed to start their own companies.
We should try to learn some vocational skills because they make us ready for jobs right after training. These skills prepare us for specific careers and industries and allow career flexibility.
In class, talk about a vocational skill you wish to develop and why.

Natural Disasters
Natural disasters are unexpected and powerful events, such as earthquakes or floods. They can harm the environment, property and people. Let us read about some of these disasters.
Earthquake: An earthquake happens when there is a movement beneath the Earth’s surface, causing the ground to shake a lot. It can cause buildings to collapse and even lead to landslides.
The Noto Peninsula Earthquake was a major earthquake that took place in Japan on 1 January 2024.
Flood: A flood is caused by an overflow of water on land. It can happen due to heavy rain, ocean waves, rapidly melting snow, dam failures or cloudbursts (a sudden, very heavy rainfall). Floods can lead to loss of lives, buildings and roads. Dirty and stagnant water that collects due to floods can cause several diseases like typhoid, malaria and various types of skin infections. Heavy rainfall during the rainy season of 2024 caused severe flooding in Assam, India.
Landslide: A landslide refers to a mass movement of rocks or a shallow flow of debris (scattered pieces of rubbish) down a slope. Landslides can be caused by rain, earthquakes or volcanic eruptions. Human activities like cutting down trees have increased the risk of landslides. The easiest way to prevent landslides is to plant more trees. In 2024, a series of landslides hit Wayanad district in Kerala. They caused a lot of destruction.
Cyclones: A cyclone is a huge, spinning mass of air that forms over the sea and moves towards the land. It can bring heavy rains, high waves and strong winds. The wind can damage houses, trees and buildings. The government usually issues warnings before a cyclone hits, which helps save lives. Cyclone Remal was a strong cyclone that hit West Bengal in India and Bangladesh in May 2024.
Caring for the environment helps reduce the risk and impact of natural disasters. By protecting forests, rivers and oceans, and planting more trees, we create a healthier Earth that can better withstand events like floods and landslides.

Different Ways of Earning Money
People do different kinds of work to earn money. Let us learn more about the different ways in which people can support themselves.
We need money for our daily lives. We earn money by doing work. The money that we earn by working is called our income. The regular work that people do to earn money is called a job. The fixed amount of money they get for doing a full-time job is called their salary. If people are paid by the hour, or for a piece-by-piece job, we call their earnings wages.
A business is an organisation that produces or sells products or services to get money. People also start their own businesses in order to earn money. They produce or sell different things like food, clothes, books and building materials.
An entrepreneur is a person who starts or owns a business.
A part-time job is a job that people do for a few hours a week. People work for less time than in a full-time job. In a part-time job, people are paid based on the number of hours they work.
Some examples of jobs that can be part-time are tutoring, dog walking and driving.
In today’s evolving world, whether you choose to pursue a job or start a business, certain skills like critical thinking, creativity and effective communication are very important.
