"One small step for a man-one giant step for mankind" - Neil Armstrong This S.T.E.M. lesson is designed to show the students how rockets work, the design process, and make connections with how they are used in their daily lives. Students will build their own prototype rocket, mostly from scratch. Most of our everyday life depends on rockets. Satellites were launched by rockets which send signals back to earth for our GPS systems, televisions, and cell phones. They even help send images back so we can predict the weather and see what countries are doing around the world. The model rockets are launched just like the real ones: with electrical ignition, a launching tower, countdown and recovery system.

"For every action there is an equal but opposite reaction." - Isaac Newton PA Standards 3.4.10.D1: Refine a design by using prototypes and modeling to ensure quality, efficiency, and productivity of a final product. 3.4.10.E5: Analyze the development of transportation services and methods and their impact on society 3.4.10.B4: Recognize that technological development has been evolutionary, the result of a series of refinements to a basic invention. Stages of a launch1. Ignition - 10-9-8-7-6-5-4-3-2-1...Blast off!
2. Lift off then burnout - Engine thrust pushes rocket until propellant burns out, then momentum carries rocket upward. 3. Apogee - Peak altitude of rocket or highest point in the rocket flight 4. Ejection - Charge pushes out a parachute 5. Landing - Rocket descends slowly landing undamaged for another flight (if successful)
