2. Heating is a means by which energy can be transferred.
What is heating?
Heating is a means by which energy can be transferred.

3. What is a conductor?
Energy, such as heat, transfers through some materials easily. These materials are called conductors. Metals are great conductors because energy passes through them quickly

8. Our Experiment
We will carry out an experiment to see which material is the best insulator

9. Materials
*thermometers *elastic bands *6 jam jars with lids *a scissors *cotton wool , newspaper, tissue paper, some cloth, aluminium foil *warm water

10. Method Set up a fair test
Insulate (wrap material around) 5 of the jars
Jar 1: with cotton wool
Jar 2: with newspaper
Jar 3: with cloth
Jar 4: with aluminium foil
Jar 5: with tissue paper
Jar 6: no insulation

11. 2. Fill each jar with warm water
2. Fill each jar with warm water. Put the same amount of water in each jar 3. Take the temperature of the water in each jar and record it 4. Take the temperature of the water in each jar every 5 minutes for half an hour. Record your findings

12. 5. Which jar has lost the least heat. Was it insulated. With what. 6
5. Which jar has lost the least heat? Was it insulated? With what? 6. Which jar lost the most heat? 7. What conclusions do you draw about materials for insulation?
