Welcome to this page!What an exciting and busy term we have in Term 3!
Mrs Maple is going to work for six weeks in Room 7 (and in the other Junior rooms)
teaching our children about 'ENERGY', every Monday morning so we can spend therest of the week thinking and revisiting what Mrs Maple has taught us.
Over the weeks, this page will be added to showing what our class has been learning,
the questions we ask and answer, the experiments Mrs Maple has Room 7do...and much, much more!
Some of the key focus words that we will be learning, may be in Bold print,
and if they are also highlighted or underlined, the words may take youto another link/page if you click on them so you can learn more about that word.On those pages will be some of the experiments (also seen on this page) and
questions we pose (hypotheses).

Week 1 - Introduction*What is energy?*What types of energy are there?*What are some of the examples of energy?Mrs Maple showed us that there are different types of energy. We learnt about 6 of them.
See if you can remember or guess what the pictures might mean.
Un-jumble the letters.to see what each answer is.
Each word starts with the capital letter.

Well done if you figured out the answers!!! (Keep guessing if you haven't yet :)
Here is a neat little YouTube clip that talks about 'What is energy?' and 'Types of Energy' (in thevideo, the man introduces some more types of energy).

We learnt that ...

Also, a 'hypothesis' is a 'very good calculated guess' based on things you know but
you want to see what happens if you try something different using some of the
same knowledge! Remember this word because you will 'hypothesize' on these
pages a lot! It will be given a 'question mark' picture like this one.
question 3.jpg
Mrs Maple asked Room 7, "If energy can make something happen and that it can move things,
or it can heat things up and make things change...what happens when you might bake a cake?"

*How is the cake mixture different to the cake after heat has been applied to the mixture?
You are mixing the cake mixture and ...

1. What does it look like?
2. What is its texture?
cake mixture.png
baked cake.jpg
After you have baked it in the oven...

1. What does it look like now?
2. What does its texture feel like now?
3. How has the cake mixture changed?
4. What type of energy was given to
cake mixture to make it change?

"Energy can make something happen".

We learnt about energy that is applied to these types of energy.
1. Potential energy
2. Kinetic energy

*Potential energy is stored up energy that is ready to be used. Potential energy can be stored
in different ways and can be given energy in different ways depending on the object.

***Kinetic energy** is energy that is being used in some way.

Here is a neat little YouTube clip that describes 'Kinetic' and 'Potential' energy!

Activity #1 - The Ball - Kinetic Energy


When the ball was very still, it had NO ENERGY but then we got into a big circle and Mrs Maple began to pass the

ball around to different kids and started to move the ball around the circle and we gave it kinetic energy. Next she stood up and held the ball above the ground about where her knees were and then she...
What do you think happened?
Mrs Maple then held the ball higher to give it potential energy and then she let the balloon use the energy by turning its potential energy into kinetic energy...
How do you think she did that?What is your hypothesis?
question 2.png
*What do you think she did to give the ball more potential energy?
*What things happened when the ball used all that energy up?

*Click on the video to find out.

Activity #2 - The Balloons
Mrs Maple then gave three children some balloons.

question 4.jpg
*How will the children give the balloons stored-up potential energy?*How will the balloons use up the potential energy turning it into kinetic energy?*What happens if you give each balloon different amounts of energy?
*Click on the video to find out.

Activity #3 - Cars!Mrs Maple then had two cars that she wanted to move by themselves...but how?
*How do you think Mrs Maple got the cars to move with their own 'stored up' potential energy?*Did Mrs Maple use fuel energy? Chemical energy? Mechanical energy? Wind energy?
Make your hypothesis.

Now click on the video to see if you were correct!

Activity #4 - Tractors using Kinetic energyMrs Maple described how things can store up energy in different ways.Watch the video and see how Mrs Maple helped the tractor to store up 'potential energy'.
Click on the video and observe what Mrs Maple did then answer the questions afterwards!
Questions - Nga Patai!*How did Mrs Maple apply energy to the tractor?*How was energy being stored up in the tractor?(Think about what the parts of the tractor are!)*How was energy released and turned into kinetic energy?
Observe again how potential energy was turned into kinetic energy.
Some of Room 7 children are using the tractor wheels in pairs and observing howthe tractor wheel is moving, what tractor-part they can see is doing...and hopefullythinking about what the 'elastic rubber band' inside the tractor wheel is doing!!!

Week - TwoWhat did we talk about?*We revisited 'potential' and 'kinetic' energy*Mrs Maple introduced our children to 'Mechanical Energy'*Room 7 'conducted' experiments - timing how long our mechanical spiders could go for!- Room 7 had to 'time' how long the mechanical spiders would work forand then the children had to give more 'potential' energy to the spidersto make them go for longer.

Here we are practising to turn the keys on the mechanical spiders.

Here we are using the 'stop-watches' Mrs Maple gave us to time the 'Mechanical Spiders'.

Here we are recording our results and comparing.

Week ThreePower-it-Up!!!How could you make a simple 'electric circuit' using these objects to make the 'light bulb' glow?

Week 4

Week 5Brain Boxes Galore!Room 7 have worked with simple circuits, have experimented with adding, taking-awayand figuring out what will happen if... and so on. A lot of simplehypothesis making and conducting simple experiments to find out have occurred.
Mrs Maple discussed negative and positive ends of a battery and reminded Room 7how to keep the electric energy passing through the circuit in order to helpthe 'load' use that energy.
What is a load?To find out, have a look at these picture slides and video to find out.Here's a clue...you have the circuit to let the electrical energy flow but you add something(the load) to use that electrical energy and most of the time, you can see the load working!

Week 6 - EnergyWhat can use you use to help create energy without using chemical energy like in a battery?

Inside this torch that is not battery-run, you will find these materials...

Some way to move the magnet past the copper wire to create energy

Here is the worksheet the children filled out with Mrs Maple. See if you can spy how the energymoves pass the copper wire20130902_093903.jpg
Mrs Maple had to move the magnet past the copper wire a lot of times to create energy.We didn't have a spare 'wind turbine' and we were not near a river.How do you think Mrs Maple moved the battery? Look at the picture carefully to find out.
The answer has been written backwards:.ti koohs ehS

Week 7 - How can save energy in our homes and become more 'Energy Efficient?'

What could we do to save energy......in the kitchen?

...in the lounge?

...in the garage?

...in the bedroom?
