The second and third grade STEM Club members kicked off the New Year by constructing catapults! Mrs. Owen handed each group a wire hanger, spoon, rubber bands, and some marshmallows. It was then up to the STEM Club members to try to figure out how to construct a catapult that would launch a marshmallow the farthest distance across the room. Not an easy task! Here are some designs.
After testing their own designs, Mrs. Owen showed the club a design she learned at a workshop over the summer. The groups made models after Mrs. Owen's design, and tested their catapults again to see if their distance improved, or if their original designs faired better. We then had a marshmallow chunking contest using our catapults, where each group faced off against one another.
