Experimenting with energy

This term we are going to learn about energies in our CLIL lessons. Last Friday we were working on stored energy and mechanical energy. We were using a piece of string and a lid.

These are the instructions our teachers gave us.

You need:
- a piece of string
- a lid

First, make two holes in the lid (like a button).
Put the string trough both holes and tie the ends into a knot.
Put both index fingers inside the string on the ends.
Wind up the string and begin to pull your fingers outwards.
Let your hands move with the string as the stores energy is converted into mechanical energy.

It was not easy to make the lid spin in the correct way but it was awesome when we did.
