Electricity and Circuits

This term the year sixes are learning about electrical energy and this week we were studying how electrical circuits work. 


A circuit is a closed path or loop around which an electric current flows.


A circuit is usually made by linking electrical components together with pieces of wire cable. Thus, in a flashlight, there is a simple circuit with a switch, a light globe, and a battery linked together by a few short pieces of copper wire. When you turn the switch on, electricity flows around the circuit. If there is a break anywhere in the circuit, electricity cannot flow. If one of the wires is broken, for example, the globe will not light up.


We had to predict and trial ways to assemble a battery, light globe and some wires to make the bulb light up. It was a lot of fun testing out different ways to put together the parts to assemble a complete or closed circuit. We discovered ways to use two wires as well as one.

After drawing illustrated diagrams of our circuits we compared them to ‘circuit diagrams’ used by electricians. We learnt some of the symbols used to draw circuit diagrams and then drew our own.
