Odds and Evens






We have been doing maths stations to warm up our brains for maths. We found out that when you add an even and an odd you get an odd number. When you add two even numbers you get an even number. Finally when you add two odd numbers you always get an even number. Check out our photos of our ordering numbers stations.
Max talked to us about magnets. A magnet has 2 poles a south and a north. Thanks Max for the cool experiment.

What is energy?





Annabel and Oscar shared some exciting news on What is Energy?
Annabel and her family built a water wheel. We tried it out and thought it was awesome.
We learnt that a water wheel is a hydropower system. It makes power from the flow of water. It is made up of a large wheel. The wheel is made of wood or of metal.

Oscar and Miss Brown made a lemon battery. We found it worked with just two lemons. When we added extra lemons the LED became brighter. The acid from the lemon makes chemical energy and then it is turned into electrical energy.
Oscar watched this Youtube video at home with his Dad. It is where he got the idea. Thank you to Oscar's family for supplying us with the equipment we needed.

Scientists




We are learning about what is energy??? These are the key understandings:
Energy makes things happen by generating forces that do different types of work.

Energy can change its form e.g. electrical energy changes into light energy when it travels through a bulb.

Physics (The study of energy) affects our everyday life.


Here are some photos of the great home learning we have been doing on What is energy?
Liam talked about what car batteries do. Tim told us about conductors and insulators. He told us that: A conductor lets electric current flow through it.
An insulator does not let an electric current flow through it. Holly showed us her phone, it needs batteries to work too!!!!
