William Kelley Schools physics students braved the chilly waters of Lake Superior on May 5 to test out their boats made of cardboard, paint and glue at the Silver Bay Marina.

As part of their physics class, students worked together in groups to create their boats and paddle them around the marina. The purpose of the project is to demonstrate Archimedes's principle that calculates water displacement based on the weight of the participants and the boat. The students then use their calculations to predict where the waterline on the boat should be.
