In this lesson, students design and construct a boat out of aluminum foil and a few other simple materials. The boats will then be tested by floating them in a pool or sink of water, and then adding mass until they sink. Students will begin to understand the scientific laws required for the design of the boat, i.e. buoyancy and Archimedes Principle. They will also explore the shapes of boats and construction techniques that may work for the boats. Science NetLinks provides student handouts, links to helpful web resources, and detailed instructions for completing the lesson.
