Aim: To show that electricity will flow through some materials and not others.
Method: Using a power pack, clip wires and a light bulb set up the following circuit.
Test different objects to see if the light goes and it conducts electricity. If the light doesn’t glow, it is an insulator.
NB. Or other objects the teacher chooses. Place a tick in the column to show it is a conductor or an insulator.
Conclusion: Write a conclusion stating:
• What materials are good conductors of electricity.
• What materials are insulators of electricity.
Explain, using diagrams and notes, why some materials are able to conduct electricity.
