CONCLUSION: 1. Describe one possible trend in the data. the duller or darker the colour of the can, the more the water heats up

2. Explain why we can only say it is a 'possible' trend. we need to do more than one test and different types of tests also because we can't just make our decision on one incident because it may be wrong.

DISCUSSION: 1. Explain the trend above in terms of how heat moves. heat/light is attracted to darker colours/colours that absorb more light

2. Discuss how the experiment could be improved. we need to make sure that all the cans are the same shape/height/volume. We also need to do the experiment more than once, just to be sure.

__**Heat and Temperature**__
This experiment shows that the less liquid there is the faster the heat will travel through it. It also shows that a certain quantity oil heats slower than the same amount of water.

__**convection**__ Convectional currents define currents of gas/liquid that are going up when hot, hense forcing the cool liquid/gas to go down. Convectional currents can be found in a saucepan of water. The water closest to the bottom of the pan heats up and rises to the top, forcing the cooler water down. The cooler water then heats up at the bottom of the pan and rises, and the cycle continues until the water is evaporated or the source of heat (in this case the fire) is turned off.



__**Radiation**__
Radiation is heat being given off all around a hot object. Radiation can occur with an oil heater. The air around the heater gets warm and we can feelit. It radiates heat.

The Sun also radiates heat that we can feel on Earth.

__**Conducting**__
Heat can pass from one object to another. Some objects are better at conducting heat than others. Plastic is not a good conducter of heat while metal is.

Most saucepans are made of heat because they conduct heat to the food well.
