We use so many things every day that rely on electricity to make them work!

Some things get their electricity by plugging them into the mains power supply and others get their electric power from batteries. But wherever the power comes from, electricity can only do its work if it is able to flow in a circuit.

A circuit can be as simple as a source of electricity (such as a battery) a light bulb and a switch. 

Let's use this activity to test what we know about circuits and how electricity flows through them.
