Solar Cooker Project
Comments: 1
Question and hypothesis
My question is will the size of the solar cooker affect the temperature.
My hypothesis is the size will affect the temperature.
Procedure1. Research online for information about solar energy.
2. Build solar cooker.
3. Put the solar cooker in the shade for ten minutes to get a baseline temperature.
4. Put the solar cooker in the sunlight and record the temperature every two minutes in a t-chart.
5. Make any adjustments you think you need and repeat steps 3 and 4.
Results2. Build solar cooker.
3. Put the solar cooker in the shade for ten minutes to get a baseline temperature.
4. Put the solar cooker in the sunlight and record the temperature every two minutes in a t-chart.
5. Make any adjustments you think you need and repeat steps 3 and 4.
Conclusion
In conclusion, the size did affect the temperature because the smaller box cooker had a higher temperature than the larger box cooker, as shown in the results above.
Discussion
I think solar energy use reduces environmental pollution because the sun's rays are a clean resource to use than oil or natural gas. I had to conduct two tests because I might have needed to make some adjustments to get the temperature to go up. One observation is the largest solar cooker doesn't always have the highest temperature. One inference is that according to the results, the smaller cooker could hold more heat in than the larger cooker.

Overall, this is a good project. However, your grade suffered because you left out a few important details.
Question - 2/3 - Your question is testable, but your hypothesis is not written correctly. How will size affect temperature?
Procedures - 2/3 - Logical and easy-to-follow, however you forgot to tell how long to test your cooker.
Results - 3/3 - Your graph contains all required items.
Conclusion - 1/3 - Your conclusion doesn't include an explanation of why you got the results you did. It also doesn't include any predictions.
Discussion - 2/3 - Your inference is actually an observation. What conclusion could you draw from that observation.
Total - 10/15
