Method

Before I write out my method, I need to write out how to set up the equipment.

Set up Equipment
1. Paint container with 6mL of white paint
2. Mix 2mL of white paint and 4mL of black paint and paint it on the plastic container
3. Repeat but with 3mL of each colour and paint
4. Repeat with 4mL of white paint and 2mL of black paint
5. Paint the container with 6mL of black paint
6. Wait until all the paint dries, leave it for 24 hours
7. Cover the other jars with yellow, blue and red cellophane.
8. Keep one container clear as the control.
9. Pour 100ml of water into each container.

Method
The equipment was set up and the 9 plastic containers were all set up 10 centimetres away from the light bulb. The temperature of the water in each jar was then measured and recorded. The light bulb was switched on and kept on for 1 hour. The themometer was then placed into each container and the temperature was recorded. This was then repeated 3 more times, one, 2 days later, another 4 days later and the last one 6 days later.
