On one of the coldest days of March, STEM students set about the task of testing cardboard boats. The boats are 1/4 scale replicas of the boats they will be building after spring break to compete in the Whatever Floats Your Boat regatta. The regatta will be held at the Liberty Township YMCA May 4 at 8 am. STEM sophomores studying buoyancy and the engineering design process will build the boats and attempt to ride in them in the YMCA pool. This activity is designed to reinforce collaboration, prototyping and scale modeling.
