Steve Hearn from the Institute of Physics shows a group of non-specialist physics teachers from the London Borough of Barnet how to approach the subject of electricity at KS3, a topic which teachers and students find difficult. He introduces them to a torch with no batteries, an electrical board which allows students to connect a wide variety of components in a circuit, and fruit batteries. One of the teachers in the group, then takes on the task of teaching electricity to her Year 9 group. The students use the electricity board for the first time, work out how to generate electricity using a shaky torch with no batteries and discover whether batteries made out of tomatoes are better than those made from bananas and other fruit.
