Solar Ovens
Third grade environmentalists used solar power, an alternative energy source that is clean and renewable, to cook s’mores. The heat is transferred using radiation waves from the sun. We viewed several different design option for solar ovens and identified the common features. Click here to learn more about constructing solar ovens.
One of the assignments in the Upper School’s environmental studies class is to design a solar oven that can boil water, so this was a fun introductory investigation. Click here to watch college freshmen design solar ovens.
As we walked back to the lab, we placed our hand on a white car and then a black car in the parking lot. Heat passed through conduction, and we were amazed at how much hotter the black car felt. Dark colors absorb more light energy.
Back in the lab, I also shared some other items that are powered by solar energy. Look how fast the animals on the back table are moving. They are in the sunlight.
