This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction. Learners will harness the power of thrust forces to build a rocket pinwheel. They will do this by making a pinwheel with a balloon, straw and pin. Thrust causes the balloon to spin around in a circular motion. [Activity is publicly available through a web crawler capture on Archive.org. Activity write-up only, images are unavailable.]
