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 make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.

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 activity, learners build a nanorover model using styrofoam meat trays and a balloon.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this experiment, learners investigate how the size of a wing affects lift. Learners count the number of pennies an egg crate plane wing can hold until the plane will no longer fly.
