Electricity at Key Stage 3 can be a difficult subject, so Steve Hearn from the Institute of Physics shows a group of non-specialist physics teachers from the London Borough of Barnet how best to approach it.
He introduces them to a torch with no batteries and an electrical board which allows students to connect a wide variety of components in a circuit, such as fruit batteries.
One of the teachers in the group, Kelly Foulser, then takes on the task of teaching electricity to her Year 9 group using these techniques. The students use the electricity board for the first time, they work out how to generate electricity using a torch with no batteries and discover whether batteries made out of tomatoes are better than those made from bananas and other fruit.
