In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.
