This week we are starting a new unit about Electricity. What do you know about electricity already? Most of you know what it feels like to get a shock from an electric fence and have felt a ‘static’ shock when opening a car door or getting off a trampoline. But what is it that you are feeling? We will demonstrate the use of a Van der Graaf generator in class.
The first task is to write a list from A to Z of the equipment that uses electricity to make it work. All these appliances use an electric current that flows from the source (a power station), through high voltage power lines, transformers, local power lines, to your home, into the appliance and back again. Any electrical appliance relies on a complete circuit of conductors that allows the flow of electrons. Those electrons are the negatively charged particles that are present outside all atoms, and in a coil of wire, with magnets, they can move.Find out more about electricity here:
