Question and Hypothesis
My question was: can a smaller cooker get hotter than a bigger cooker?
My hypothesis was: yes a smaller cooker will have less air to heat and get hotter than a bigger cooker quicker.
Scientific ProceduresMy hypothesis was: yes a smaller cooker will have less air to heat and get hotter than a bigger cooker quicker.
1.Research solar energy and find plans for cooker.
2.Build solar cooker.
3.Test cookers outside and record results.
4.Test cookers a second time and record results.
5.Compare results with another person to test hypothesis.

Conclusions
In conclusion, my hypothesis was correct, the smaller cooker was hotter than the larger one in both tests. It might be this way because of the smaller amount of space a smaller cooker has to heat. The difference in temperature was not that great, only six degrees. This might have been because of the larger amount of sunlight captured and focused on the thermometer by the larger cooker.
DiscussionSolar energy reduces enviromental by not giving off any biproducts or pollution. Also solar energy is a renewable resource and will not run out or damage the enviroment to get it. We had to conduct two tests in case we had done anything wrong and our temperature was inacurate or to test our hypothesis by changing a part of the cooker. Since the temperature difference was only six degrees the size of a cooker must not affect the cooker very much.
