In the Paper Sailboat Speed Test STEM Challenge, students become marine and mechanical engineers as they design and build a paper sailboat that uses wind power to move as fast and as far as possible across water. Through hands-on experimentation, students explore how wind force, sail shape, surface area, drag, and stability affect speed and motion while applying the Engineering Design Process. This exciting, low-prep STEM challenge is perfect for STEM labs, science classrooms, engineering u
