On the next hot day, I started by putting an iron skillet on my dashboard for a while to heat up. After it was really hot, I cracked an egg into it and closed the car. Then I waited. And waited. But that was okay because my sister-in-law said that solar ovens cook very slowly--even slower than a slow cooker sometimes. When the sun started to go down, I retrieved the egg. Guess what I found? A raw egg.
If I were really serious about these experiments, I would be carefully studying my techniques and researching the properties of the materials I am using--doing a complete scientific analysis. However, I'm not serious in that way. I'm serious in an impulsive sort of way. Meaning when it's hot outside, it's time to crack an egg and see what happens. This method reminds me of one of the ways they taught my kids how to do math problems. It was call the "guess and check"--meaning you guess at the answer and then plug it back into the problem to see if it is right. I thought that was a crazy method at the time. However, I kind of like that model for my egg experiments.
