- This spring, my friend Melissa and I decided to enter the school science fair. We wanted to create something original and useful, so we started working on a solar oven. After asking our science teacher for advice, we made a list of the materials we would need and spent a weekend building and testing our idea. It wasn't easy. The first version didn't work at all. But we didn't give up. We tried again - this time with better insulation. It worked! We managed to heat water and cook simple food using sunlight. On the day of the fair, we presented our oven to the judges. They loved it and gave us second prize!
