We learnt about the movement of electrons that makes electricity. We hooked up zinc and copper wires between potatoes or lemons. The electrons ran from the zinc to the copper and made electricity to make the clock go.
We also used baking soda, water, and then blackcurrant juice to make invisible writing.
