In science this half term, we started off by learning about the difference between mains and battery powered appliances in the home. We then made our own simple circuits and discovered that in order for a bulb to light, the circuit had to be complete.

A switch is used to create a gap in a circuit which means that the electrical current can’t flow. The appliance will only work when the gap has been closed by pressing the switch.

We found out that materials which are insulators of electricity are important for our safety. We designed and carried out an experiment to find out which materials conducted electricity. Despite tin foil being light, thin and crumpled, it still conducted electricity as it is a metal!
