Design and make a model or toy that shows an energy transformation/s?

Question

I really need some ideas please!

Answer 1

A rubber band powered toy would be easiest I think. This link is for rubber band powered vehicles, but it has other pages for other kinds of rubber band powered toys you can use for inspiration.

The wound, or otherwise stretched, rubber band has potential energy which is converted to kinetic energy when it's released.

Answer 2

I think that should be a battery operated toy like robots, talking toys, etc. I hope this helps
