ObjectiveThe third lesson asks the students to refer back to their drawings on the previous worksheet and attempt improve upon their oven design after a general discussion of ways to increase the efficiency of solar ovens. They can compare their design with other commercially available oven types and using additional construction materials actually build their ovens. The apple slice experiment from Part II is repeated and the previously recorded data serves to demonstrate improved performance of their personal oven.
