Students use a planar model of a gravity well to create different orbital configurations around a central mass.

Students predict and observe what happens when two objects collide to model collisions in space.

Students will investigate the action-reaction principal (Newton's third law of motion) by creating water-propelled engines and changing different variables to see how their engines perform.

Students perform a simple science experiment to learn how a rocket works and demonstrate Newton’s third law of motion.

Students construct balloon-powered rockets to launch the greatest payload possible to the classroom ceiling.

In this lesson, students build a paper helicopter, then improve the design and compare and measure performance.

In this illustrated problem set, students use pi to collect samples from an asteroid, fly a helicopter on Mars for the first time, find efficient ways to talk with distant spacecraft, and study the forces behind Earth's beautiful auroras.

Students design and build a shock-absorbing system that will protect two "astronauts" when they land.

Students design, build and program a robotic “super crawler” to transport a payload from a starting position to a target launch pad, deliver the payload in an upright position and return the robot to the starting point.
