Fifth grade students at Savanna Ridge Elementary School enjoyed a day of STEM learning. Their task was to design, construct and test solar ovens to demonstrate the transformation of solar energy to thermal energy. After researching different designs, students were given materials to construct a solar oven from a pizza box. They tested their ovens first by melting a square of chocolate for three minutes. They returned to the lab to make adjustments to their designs before making s’mores. Through the STEM activity students reinforced content learned in the classroom and of course, the s’mores were enjoyed by all.
