In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.

In this activity, learners discover how NASA engineers develop experimental aircraft.

In this activity, learners work in NASA teams to build balloon-powered rockets using identical parts and compete to launch the greatest number of paper clips to "space" (the ceiling).

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.
