Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black. The black surface absorbs the sunlight and produces heat which can be used to bake brownies, cookies, vegetables, or even warm soups and pizza. Use this activity to introduce learners to renewable energy and the Sun as a source of energy. Main webpage includes links to other related resources. Note: Solar ovens can get very hot. Oven mitts or gloves and adult supervision required.
