Teachers’ Notes “I have no special talents. I am only passionately curious.” – Albert Einstein Science, Technology, Engineering and Maths are the integrated learning areas known as STEM. STEM requires students to problem-solve and think critically and with a degree of flexibility. The Australian Government through the National Innovation and Science Agenda (Australian Government, Department of Education and Training, December 2015) have shone a spotlight on the importance of students having problem-solving and innovative thinking skills. The workplaces of the future will increasingly rely on students to be able to think critically and flexibly to address the fast moving pace of the world. This book supports teachers to develop inquiry-based learning in the classroom across Science, Mathematics and Technologies. Literacy is also important as a General Capability and is interwoven in the tasks encouraging students to express their discoveries in a variety of ways (AC, v. 8.3, Literacy). This resource is written for students in Years 2 and 3. The book is broken into four main sections. The first section focuses on the core Science and Engineering inquiry skills with a variety of challenging investigations outlined. The content is generally outlined in the first part of each topic and more challenging investigations are then included. The second section reviews the science of forces with opportunities for small and larger group investigations. Following from this, the third section comprises more in-depth inquiry-based investigations. These are group tasks all focussed on a particular question. The final section is a series of shorter investigations that require the use of low-cost materials that are easily available. These investigations could be conducted as rotations with students in a weekly lesson.

Enjoy the ride with your students – STEM can take the students in many unexpected directions. This resource offers students opportunities to: practise working in small groups cooperating and collaborating; experience failure when activities have unexpected results; time to reflect on what happened and how things could be developed further. All of these opportunities are vital experiences for children. Embrace the unknown and look for the teaching moments to highlight. After all, according to T.S. Eliot, it is perhaps the journey that is most important and not the destination.

Create A Questions Wall

Imaginary Interview

The Top Three Game (3 minutes)

Find A Local Brain

Everyone thinks of three things they know about a topic. Students pair up and exchange their three points. Repeat this again and swap information with others in the class until time is up.

Invite an expert into the classroom to give a talk on a topic. Put the call out to parents in the community or contact your local university. Check out the CSIRO Scientists in Schools program to check who might also be able to assist: www.csiro.au

Start A Curiosity Corner

Where To Next?

So What?

Class Investigation Book

Make a poster where students can write any questions they have and stick them onto the wall. These could be explored further in class discussion time. Use glass markers and have students write them directly onto windows as an alternative.

Ask the class to bring in items that may connect to a topic. Print off interesting articles or images to make a hands-on learning corner.

In pairs, ask students to imagine what could be done with the information they have discovered. Ask them what could be made better? What could be invented? What could be improved?

Ask your students to imagine they are reporters interviewing an expert on the topic that you are exploring. They must write lists of questions to ask the experts based on their knowledge. Record these using devices (iPads / computers) and playback to the class.

Students draw up a road map showing what they have done so far, what they have learnt and what could happen next â&#x20AC;&#x201C; do these on A3 paper and put them up around the room. Discuss and compare the differences between ideas. Celebrate the variety of perspectives.

Have a class photographer (or take turns) capture photos to document the STEM activities. Collate these to make a class book either digitally or in hard copy.

Forming Groups Use these ideas to help organise your students into groups and keep them on their toes. Encourage them to make connections with others and develop cooperation and collaboration skills.

Making Pairs •

Put name tag cards into a container and draw them out.

•

Number off 1, 2 to form pairs.

•

Students form pairs by finding someone of similar height, with same birthday month, has the same favourite food, number of sibilings, etc.

•

Hand out playing cards. Ask students to find their match (e.g. Queen of Hearts matches Queen of Diamonds, 4 of Clubs matches 4 of Spades, etc.).

Making Groups •

Give students coloured stickers. Without talking, students must form groups according to their sticker colour.

•

Give each student an animal name. Each class member closes eyes and makes the animal noise to find the other members of their group.

•

Write numbers or letters onto ping pong balls. Throw them to each student. Groups are formed according to the balls (all 2s together, etc.). Keep these and reuse them.

Icebreakers (get your class tuned in and ready to go) •

Students line up according to the number of letters in their name / number of people living in their house / number of pets they have / birthday / shortest to tallest (do this without talking for a real challenge).

•

Each student thinks of a positive adjective to describe themselves that starts with their initials (e.g. M.E. = marvellous and energetic). Students sort into alphabetical order according to initials and share their adjectives.

•

Speed share: form pairs, have students face each other and create a circle with the class. The teacher stands in the centre and gives a speaking topic. “My greatest wish is … / I really love to … / I want to find out about … / I will never … ” Allow 30 seconds to discuss the topic with the student facing them. Then the outside circle moves to a new partner and speed share starts again.

“Millions of people saw the apple fall, but Newton asked why.” – Bernard Baruch

Reasons A. Corrosion: metals are strong but they can rust over time due to wind and rain B. Fatigue: heavy loads on bridges and walls cause cracks and breaks over time C. People or animals â&#x20AC;&#x201C; behaviour can cause materials to break D. Erosion â&#x20AC;&#x201C; weather elements can cause materials to break down (wind, water, sun exposure) 17

Bridges 1

experiment activity

Bridges connect two places and allow people and things to be safely carried across. Different bridge designs are needed for different situations. Around the world there are many different types of bridges that have been built.

TTIn pairs study the bridges below. Do you know any of these types of bridges?

Arch Bridge

Beam Bridge

Curved with abutments at each end that support the weight of the bridge. Arched shaped with short span range.

Simple structure supported at the ends or by pillars. Examples are wooden planks or stone slabs laid across streams.

Wooden Truss Bridge

Suspension Bridge

Typically carries pedestrians and automobiles over short distances. Made from connecting triangular units.

The deck is hung below cables, suspended between towers that hold the weight up. Span range is medium to long. This bridge can carry light rail.

1. Which bridge would be the cheapest to build? _______________________________________________________________ 2. Which bridge would be best to use over a long distance? _______________________________________________________________ 3. Which bridge would be used over short distances? _______________________________________________________________ 4. Which bridge can carry the heaviest load? _______________________________________________________________ 18

Bridge 2

activity

TTIn a group of three, make a beam bridge using rectangular bricks. Your beam bridge must be able to hold a light load; and toy cars should be able to pass underneath it.

Materials:

template on page 20 to make rectangular bricks sticky tape scissors exercise book to use as a light load toy car to pass underneath the beam bridge

N.B. Bridge is a success if it can hold a light weight (exercise book) without collapsing and a toy car can pass underneath.

Investigating Domes

activity

The geodesic dome structure was named and popularised by an American architect, Buckmister Fuller, in 1954. Domes are very strong and able to bear a heavy load making them very sturdy structures.

1. Look carefully at this dome structure. What shapes make up a dome structure? _____________________________________ 2. Challenge Task Build your own dome then draw it in the space below. Use the materials that are specified. Materials:

ď&#x20AC;˝toothpicks ď&#x20AC;˝bluetack or playdough

3. Extra Use exercise books to test the stability of your dome. How many books can you load onto the dome before it begins to collapse?

______________________________________________________________ 21

Igloos - Dome Structures

activity

People make use of construction materials that are easy to find where they live. In cold climates, snow is easy to find and can be used to make dome-shaped homes known as igloos. Snow acts as an insulator - keeping warm air inside igloos. Igloos typically have small entrances to prevent heat from escaping.

1. Put these construction steps in order and you will know how to build an igloo. Stack each snow brick on top of one another. Make a 'brick' out of compacted snow. Mark a dome shape in the ice and show where the small entry will be. Leave small hole at the top for air ventilation. The heat from the people inside will melt the bricks together to make them strong.

2. Work in a small group to construct an ice igloo out of recycled plastic milk bottles. Look at the picture to help you plan. Think about: zz how many plastic milk bottles you will need zz how you will arrange the bottles zz creating a small entrance zz leaving a hole at the top for ventilation Materials: ď&#x20AC;˝plastic milk bottles

ď&#x20AC;˝glue or sticky tape

Results Did your igloo stay up? ______________________________________________ What could you have done better? _________________________________________________________________ _________________________________________________________________ What was the most challenging part of the build? _________________________________________________________________ _________________________________________________________________ 22

Investigating Pyramids

activity

Most of us can recognise the famous Egyptian pyramids. A pyramid is a triangular structure that converges to a single point. The base can be any polygon shape. Look at the examples below.

Name the base shape of each pyramid.

TT Construction Challenge Get into small groups and create three pyramids from three different types of materials (see below). You will need scissors, glue and/or sticky tape. Record which material made the most stable pyramid in the table provided. Materials: newspaper rolled into tubes Material

What Features Do Homes Have?

activity

1. Draw a bird's eye view of one room in your house. Use a pencil. Look at the example to help you.

2. Pair up. Compare your pencil sketch with your partner's sketch. What are two similarities and two differences between them?

3. What do you have to think about before building a home? There are many factors to consider. Number factors below in order of importance. Explain your thinking to the class. Climate – the weather conditions over time in an environment Location- flat site, rocky site, on a mountain, near the sea, desert Material – what are the best materials to use to build the house? Use – what is the home going to be used for? Family needs Cost – how much will the project cost? 24

How To Plan A House

activity

Architects are employed to design spaces that suit the needs of people. They provide plans for builders to use to construct houses. Making a plan ensures that nothing is forgotten.

TTYou are going to take on the role of an architect and design one room in a new house being built for your family. Step 1: Which room have you chosen? What does the space have to provide? Tick the items that you need and add a few of your own. natural light artificial light storage

electric sockets connecting doors windows

solid walls low or high ceilings light switches

Step 2: Gather supplies for creating your plan (ruler, sharp pencil and eraser). • Doors are marked like this: • Windows shown like this: • Lights:

• Electric sockets:

• Remember to use a bird's eye view • Label the room

Step 3: In a group, share your plan. Look for ways to improve after hearing other ideas. 25

Testing Out Materials: House Construction Challenge

activity

TTIn your group build two different houses using different materials. House 1 - Materials: paper sticky tape House 2 - Materials: plastic drinking straws sticky tape Step 1: Brainstorm your design. How will it stand up? House 1 - Paper

House 2 - Straws

Step 2: How did the building go? Tick the things that worked and cross those that need improvement. The houses were sturdy.

Fast Fact

They did not lean to one side.

A 6.4 metre tall house was once constructed entirely from paper in Thailand. It currently holds the world record for the largest paper building!

Everyone listened to each other. We used the time effectively. We tried to work together. The materials held together.

Step 3: List two things that would make your houses sturdier. House 1 - Paper

House 2 - Straws

activity

Solar is latin for the word Sun. As well as the wind, the Sun can be used to create electricity. This is called solar power! Light energy is converted to electric energy. 1. Have you ever seen solar panels fixed to the roofs of houses? Solar panels are used to power a house. When the Sun shines on solar panels, it generates DC (Direct Current) electricity. The electricity is fed into a solar inverter that changes it into AC (Alternating Current) electricity. The AC electricity is used to power appliances, such as washing machines and dishwashers found in your home. Draw a labelled diagram to illustrate this process.

Materials That Bounce!

activity

Balls are great fun. They come in many different shapes and sizes. Balls are made from a variety of materials. Some balls are designed to be bounced and others are designed to be rolled. Different materials make some balls bouncier than others. TTLook at the table below. It lists four different types of balls. They are all made with different materials. The more elastic the material; the higher the ball will bounce. Elasticity means the ability to return to an original shape after being stretched and squeezed. Make predictions about the bounciness of each ball, then test it for yourself by following the steps below. ball

Gravity And Air Resistance 1

activity

Our planet pulls everything towards its centre. This force is called gravity. We can’t see gravity but it is working on us all the time. Gravity is what keeps our feet on the ground! If there was no gravity, we would float like we do in space. When we pick things up we have to pull against gravity. When we drop things, gravity pulls these things toward the ground. Things fall at different speeds because of air resistance. Galileo, a famous scientist, discovered that an object that is more dense, or has more mass, falls at a quicker rate than a less dense object, due to air resistance. If a feather and a brick, for example, are dropped together, air resistance causes the feather to fall more slowly. Let’s Investigate Conduct the gravity and air resistance experiment below to see if Galileo was correct! Materials:  a leaf  a stone  an exercise book  an eraser stop watch Test A: Dropping items of different weight from the SAME height. Step 1: Choose two items from the above list.

Section 3: Design It

teachers' notes

General note In this section of the book, there are a number of design challenges for students to complete. They could be worked on over one lesson or extended over days. Students could complete the challenges in small groups or in pairs depending on resources available.

Introduction • • •

Start each challenge by discussing the students' prior knowledge of the topic. Together, discuss key questions that they would like answered. Guide students to think outside the box and embrace creativity and curiosity.

Assign roles Make sure everyone has a job to do. You could use roles like: • time keeper • material manager • speaker • helper • encourager • trouble-shooter • coordinator • checker

One at a time Students should be reminded to only have one person speaking at a time. Check to see everyone’s ideas are presented.

Vote on action If students can’t decide as a team, then they should vote so the decision is fairly made.

Back to the drawing board If something isn’t working – students should try another idea.

Listening is key! Check to see that students are really hearing everyone’s ideas - they can then build on them to make them even better.

Ask for help If teams are not on track, tell them it’s ok to ask for some help from you. “I can accept failure, everyone fails at something. But I can’t accept not trying” – Michael Jordan

General note The activities in this section are short and often open-ended activities designed to be highly engaging for students. Print and laminate activity cards (for easy wipe off and reuse), assemble the materials needed for each activity and put them in a labelled paper bag. Use these in the classroom for: • rotation activities • fast finishers • consolidation of tasks • rewards • rainy weather lunch breaks Add to your collection and develop more hands-on investigation materials.

Paper bag pairs rules • Look after the materials • Use only what is provided • Think outside the square - be creative • Work together, two brains are better than one • Pack up when time is up

Two stars and a wish • Encourage your students to give each other constructive feedback and reflection. At the end of an activity, each student tells/writes ‘two stars’ and ‘one wish’ for their partner. • The stars are observations about things that the person has done well. • The wish is something to improve further on next time. • It is important that the wishes are specific so students know what to work on. This can be used in larger 52

groups or as a self-reflection tool also. Scaffold this initially for your students and brainstorm things that could be stars and wishes. • Examples might include: Stars: • Solved a problem • Listened really well • Gathered all the materials • Put everything away carefully • Noticed something interesting • Asked important questions • Stayed on track Wishes: • Ran out of time - could check the clock next activity • Needed to ask teacher for help to make sure everything was clear • Would love to hear more of your ideas for solving the problems • Maybe move to a quieter place to work so not distracted
