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.
