Solar Cooker Project
Question and hypothesis
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.
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.
Plant Cell Energy
Plant cells make energy by the process called photosynthesis, in which chlorophyll in the chloroplasts captures unusable regular sunlight. The absorbed sunlight is combined with water and carbon dioxide. During photosynthesis oxygen is released and the plant cell makes a sugar called glucose. This glucose is stored in the mitochondria. Cellular respiration occurs to convert the food into energy the plant cell can use. This energy helps the plant to grow.
