Students can work individually or in groups of 3 or 4 to create a solar oven out of a pizza box. Students are trying to figure out the best way to make a solar oven in order to melt the chocolate and marshmallow in the S’more. Students will be given a group of objects and tell them the basis of how to create a solar oven. The oven will need to be placed in direct sunlight for most of the day. This experiment works best on a very hot, sunny day.
