This half term Year 4 have been learning about electricity. We carefully planned an investigation to find out which materials were conductors and insulator of electricity. We choose the materials we wanted to test and discuss how we were going to make it a fair test.

During the investigation, we created a simple circuit and tested each material within the circuit. We discovered if the bulb lit up then the material was allowing electricity to pass through it, so it must be a conductor of electricity. When the bulb did not light up we learnt that the material must be an insulator because it did not let the electricity pass through it therefore, making the circuit incomplete.

Take a look at some of the different materials we choose to investigate!
