Insulators and conductors practical
Aim: To investigate which objects conduct electricity (conductors) and which do not conduct electricity (insulators).
Materials:
- 1.5 V Battery or power pack
- 3 wires
- globe
- copper rod, plastic strip, paper, aluminium rod, nail, wood, wool, match stick, glass rod
Method:
1. Connect the globe, wires and power pack in a simple circuit.
2. Include one of the substances to be tested in the circuit and turn on the power pack to observe whether the light globe glows or not.
3. Test each of the substances, recording results in an appropriate table.
Discussion:
1. How can you conclude whether a substance is a good conductor or insulator?
2. Which substance is used to deliver electrical energy to your house?
3. Why do you think birds are able to sit on powerlines and not get electrocuted?
