This article describes an indoor, game-type demonstration, incorporating physics (EM wave modulation), math (binary codes), space technology, and music to show how spacecraft put information into the radio signals they send back to Earth. The... (View More)

Audience: Middle school

This is a activity about how reaction wheels affect spacecraft orientation (attitude). Learners will observe Newton's Third Law (action-reaction) in the changes caused by a reaction wheel acting upon a spacecraft suspended from a support wire and in... (View More)

In this experiential activity, students demonstrate to themselves the effect of the optic disc, or blind spot, inherent to the optic nerve entering the posterior of the eye (bulbus oculi). This resource is from PUMAS - Practical Uses of Math and... (View More)
