Third Grade Students Construct Solar Cookers
Students in Mrs. Rothlisberger's third grade class completed a solar cooker project. They collaborated in the study of energy and the engineering design process, then independently designed and built solar cookers from cardboard boxes, tin foil, construction paper, plastic wrap, and duct tape. The students tested the effectiveness and efficiency of their cookers using marshmallows, some of which had an internal temperature increase of over 40 degrees. They discussed possible improvements and shared their projects with other classes and parents.
