My question was which background will work better, foil, or black paper.
My hypothesis was that the foil would work better because the sun rays would bounce off it and reflect into the container with the thermometer inside. I didn't think that the black paper would be better because it just got hot inside and didn't reflect any sun to the thermometer.

1. We studied and researched the diffrent types of solar cookers and thought up a question and hypothesis. We learned about how solar cookers work and what kind of designs there are. We also picked a type of cooker we wanted and read about how to build it.
2. We gathered the supplies that we needed and following the design, we built our cookers.
3.Then, we took our cookers outside and put them in the shade for 5 minutes.We then recorded the tempature of the shaded time Then we put the cooker in the sun for ten minutes, on two minutes intervals, we checked and recoreded the tempeture on a "T chart".
