Students work in small groups to design, build, and test a speedboat powered by a hand-made propeller that pushes air. The boats are raced in a 20-foot length of eavestrough filled with water. A set of guided-inquiry worksheets has the students apply key physics concepts and equations to design their boat before building. Time is provided to test and modify their choices.
