CRAB
FOLKTALE Panchatantra:
The Heron and the Crab
A long time ago, there lived a heron, by the side of a pond brimming with fresh fish. He was a lazy creature, who wanted to find a way to catch all the fish without any effort. One day, he got an idea! He went to the side of the pond and put on a gloomy face. His friend, the crab, came alongside him and asked, “What is bothering you, my dear friend?” The heron said, “Alas, my friends! I spotted fishermen making hungry nets in the village nearby! Soon, they will come to our pond, to catch all the fish.” On hearing this, the inhabitants of the pond were devastated. The heron said, “Luckily, I know of a pond not far from here, where all the fish will be saved.” So, everyday, some fish would volunteer to be carried in the heron’s beak, to the safe pond. The heron would take the fish each day and
on reaching a large rock, he would eat all the fish, leaving nothing but their bones behind. For many days, the sly heron got a continued supply of fish without any effort. But the wise crab was suspicious of the heron’s motives and one day, volunteered to go with the heron to the new pond. As they were flying, the crab was shocked to see his friends’ bones lying around the rock. He realized there was something fishy going on, but chose to wait and watch. The heron took the crab to the rock to eat him up. Seeing this, the alert crab tightened its claws around the heron’s long neck and threatened to choke him. “Please, spare me!” cried the scared heron, knowing his game was up. The wise and merciful crab let go of the heron’s neck, who promised never to be so deceitful again. The wise crab had saved the day.

Questions about the English Language
English is the Official Language of the Sky
English seems to be the official language all over the world. Plus, it is the official language of the sky! It doesn’t matter which country they are from, all pilots speak in English on international flights. Even if you were to go to a country like Africa, the language spoken by the pilots would still be English. This is because it is the language which is understood and learnt by almost everyone around the world. These days the skies are so busy that accurate communication is most important. Communication lapses and errors can occur if different languages are used for different zones. So, English is officially used in the aviation industry worldwide to avoid any miscommunication. Imagine if the pilot of a plane landing in Africa from India communicated with ground control in Hindi, they wouldn’t understand a thing and may not let the plane land!

Treating Summer Tummies
Heat strokes can be deadly, but equally bothersome is something we're calling 'Summer Tummies'. You don't feel hungry, your tummy growls and grumbles all day long and you feel uneasy.There are several things you can do to avoid getting an overheated summer tummy. All of these suggestions are simple and involve things you can find around the house! Infusing your water with 'sabja' or sweet basil seeds helps in reducing the amount of heat trapped in the stomach and body. Sweet basil seeds, commonly confused with chia seeds, are high in antioxidants and have cooling properties. They are best used after soaking in water. As they turn gelatinous after soaking, they're easiest to drink by putting them into your drinking water bottle. Treat yourself to cooling fruits and vegetables, high in water content. These fruits and vegetables are easy to digest and don't put a strain on your body. Load up on cucumbers, tomatoes, watermelon, muskmelon, honeydew melon and gourds which have high water content. Wash everything down with lots of fresh coconut water and homemade lemonade. Fresh herbs are a must in this weather, with mint being the star of the season. Add freshly chopped mint and coriander to all of your salads. Mint can also be added to brighten up your homemade lemonade and coriander tastes delicious when added to a freshly blended buttermilk. Take advantage of the fruits available in the summer. 5

As they began to cycle on a stretch of empty road, the turned around to see an ostrich racing behind them, almost overtaking their cycles. They're sure they'll be seeing the ostrich participate in the Tour de France sometime soon!
comic story
einstien iyengar The school was abuzz with an interschool competition, an automobile show. The children had to make a car on their own, which they think would be used in the future, 50 years from now.
Martin said,“If they wanted us to make a car which already exists, I would have asked my father to just buy an exact miniature model.�
Nitin laughed and said, “The contest is not about who has more money. It is about creating something innovative.”
The science class started and the teacher discussed renewable sources of energy. How wind energy was being used to run turbines for agriculture. How steam was used to create electricity. How some villages in India had also adopted solar energy to produce electricity, for simple chores like heating the water and major areas like agriculture and even transportation.
The bell struck, but Eeshan kept thinking about what the teacher had spoken about in the class. As Eeshan, Nitin and Martin were walking towards the canteen for a lunch break, Eeshan screamed, “Eureka!” Nitin asked, “What is it Eeshan?”
“I know we can take part in the automobile show and possibly win too! Let’s enroll our names. Martin, we can talk to your uncle who owns the garage uptown. I am sure he will be a great help. And let us rope in our science teacher as the volunteer teacher in our team. We will make a car that runs on solar energy!” explained Eeshan. “It will be great if we can do it!” said Martin
They enrolled themselves and along with their science teacher, went straight to Martin’s uncle. They knew they had two weeks to make their model and participate, but they also knew making the car would not be easy.
Martin’s uncle was a huge help. First, they made the car chassis with a strong cardboard. They fit wooden wheels from Eeshan’s wooden car using a pin to create the holes. Martin’s uncle helped to put a small motor pulley on the motor shaft that would help drive the car using the solar energy.

On the day of the contest, they carried their small car to the ground. Luckily the sun in Allepey was shining brightly as usual. They connected the drive belt and the car began to run on solar energy. The other children marveled while the teachers from other schools applauded.
Predictably, they were declared winners for creating something so novel, yet doable. Einstein Iyengar and his friends were declared heroes of the school, yet again!

Pondering Corner
Types of Clouds
Clouds are formed when water vapour rises and condenses in the earth’s atmosphere. The shape and size of the fluffy white stuff in the sky is affected by a combination of factors like the temperature of the atmosphere, or the amount of water vapour present. We also have to take into consideration whether they are in the high, middle, or lower part of the atmosphere. Clouds have 4 different classifications with a Latin name CUMULUS The puffy clouds that look like floating pieces of cotton in the sky are known as cumulus clouds. They form relatively low in the earth’s atmosphere, at around 1 km above the surfacewhen hot air rises and condenses in the sky. They can appear alone or as one big mass, and are often the precursor to other types of clouds. STRATUS Stratus clouds are those which appear to be a haze in the sky. The term is used to describe any cloud that is flat, hazy, and featureless; that hangs low above the surface of the earth and can be dark gray to almost white. When you are talking about a cloudy day, it is likely that you are saying that the sky is filled with stratus clouds. NIMBUS Any cloud that produces precipitation whether rain, hail, sleet, or snow is known as a nimbus cloud. Since they are dense with water, they appear to be a gray colour. The prefix nimbo or suffix nimbus is added to the names of other clouds when they become large enough to produce precipitation. For example, cumulus – cumulonimbus and stratus – nimbostratus. CIRRUS The type of cloud that looks like someone has taken a broom and made long sweeping marks across the sky is known as a cirrus cloud. They are formed high in the atmosphere, around 6 km up- and have this appearance because the wind blows them into this formation, as the water vapour condenses. Cirrus clouds are always thin, and you can always see the sun or moon through them. 11
stories in rhyme
The Lark And Her Young Ones
Again the lark approach'd her nest, When round her all her young ones press'd, And told their mother, word for word, The fresh intelligence they heard. "Ah, children, be at ease," said she "We're safe another day, I see; For these relations, you will find, Just like his friends, will stay behind."
A lark who had her nest concealed, Says Esop, in a barley field; Began, as harvest time drew near, The reaping of the corn to fear; Afraid they would her nest descry, Before her tender brood could fly. She charged them therefore every day, Before for food she flew away, To watch the farmer in her stead, And listen well to all he said.
At dawn again the lark withdrew, And did again her charge renew. Once more the farmer early came, And found the case was just the same. The day advanced, the sun was high; But not a single help drew nigh. Then said the farmer, "Hark ye, son— I see this job will not be done, While thus we wait for friends and neighbors; So you and I'll commence our labors:
It chanced one day, she scarce was gone, Ere the farmer came and his son. The farmer well his field survey'd, And sundry observations made; At last, "I'll tell you what," said he, "This corn is fit to cut, I see; But we our neighbor's help must borrow, So tell them we begin tomorrow."
To-morrow early, we'll begin Ourselves, and get our harvest in." "Now," said the lark, when this she heard, "Our movement must not be deferr'd; For if the farmer and his son Themselves begin, 'twill soon be done."
Just after this the lark returned, When from her brood this news she learned. "Ah! dearest mother," then, said they, "Pray, let us all begone to-day." "My dears," said she, "you need not fret, I shall not be uneasy yet; For if he waits for neighbor's aid, The business long will be delay'd."
The morrow proved the lark was right; For all was cut and housed by night.
At dawn she left her nest once more, And charged her young ones as before. At five the farmer came again, And waited for his friends in vain, "Well," said the man, "I fancy, son, These friends we can't depend upon; To-morrow early, mind you go, And let our own relations know." 12
Herbert the ostrich had been given one job while his wife went in search of some food to protect their egg! His wife needed to stretch her legs and move around so he sat beside the egg, watching it very carefully. Suddenly he heard a little crack and the egg began to shake. Oh no! Was it time?

To know or not to know, that is the question! Well, wouldn’t you prefer to know?
Facts About Ostriches Ostriches are the fastest runners of any birds or other two-legged animal and can sprint at over 70 km/hr, covering up to 5m in a single stride. They have three stomachs. Lacking teeth, ostriches swallow pebbles to grind their food. An adult ostrich carries about 1kg of stones at any one time. Ostriches can go without drinking for several days, using metabolic water and moisture in ingested roots, seeds and insects. 13
