In this 1 hour long engineering challenge, learners in Grades 3-8 will design and build an air-powered rocket from a straw and launch it using a balloon. By brainstorming, designing, building, testing, evaluating, and redesigning their rockets, learners will develop skills in critical thinking, problem-solving, and scientific inquiry. They will also learn about the role rockets play in space exploration, potential and kinetic energy, and distance-angle relationships of an object in flight. Pages 3 and 4 of On the Moon: Launch It Challenge Sheet form the handout for this lesson.
