Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.

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

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.
