Electricity is SOOO useful! We have electricity in loads and loads of things that we use every day. Sometimes that electricity comes from the mains (it has to be plugged in) and sometimes it comes from batteries.
However, there are even more things we use that don't use electricity. In this worksheet you have to sort out things that need electricity from things that don't. You also have to decide whether that electrical supply comes from mains electricity or from batteries.
Should be a buzz!!
