CONCLUSION: 1. Describe one possible trend in the data. The colourful cans with colours like blue and green's temperature rose more than the other cans because deep colours absorbe light.

2. Explain why we can only say it is a 'possible' trend. Because the variables arent the same in the cans, e.g. the cans have different shapes and colours, where as to comdct a fair test then the variables need to be identical so that the changes in the experiments are all fair.

DISCUSSION: 1. Explain the trend above in terms of how heat moves. The more colourful the can is, the more it's temperature rises.

2. Discuss how the experiment could be improved. All the cans in which the experiment is conducted should be exactly the same apart from the colour, which is what we were testing. So the shape and size of can, and whether the paint is shiny or not should be the same, so that ony the colour of the cans is different, which makes the test fair.

The 3 ways in which heat moves:
 * 1**. Radiation
 * 2**. Conduction
 * 3**. Convection

When heat moves in waves, radiation occurs. An example of something that causes heat radiation is a microwave.

Conduction occurs when something obtains heat. An example is a hair straightener, it obtains heat so when it come in contact with hair it straightens it with the heat.

Convection is when something that can flow, e.g. water, oil, gas, is heated by a conductor, like water in a boiling jug or oil in a frying pan.
