Students build upon their scientific skill set as they observe, question, test, and analyze their findings in a number of longer-term projects. The salt marsh study includes a field trip to sample organisms, then a series of safe and humane controlled experiments to test student hypotheses. Studying the forces of flight, students build contraptions that manipulate lift, drag, thrust, gravity, and wind resistance. In a combined science and STEAM project, students work in partnerships to design, build and program LEGO robots using motors and sensors that respond to touch, color, and ultrasonic input.
