In this activity, learners model ancient lunar impacts using water balloons.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

In this activity, learners work in teams to investigate the composition of unseen materials using a variety of tools.

In this activity, learners model how the Moon's volcanic period reshaped its earlier features.

In this activity, pairs of learners model how scientists use craters to determine the ages of lunar surfaces. One partner keeps time while the other creates a painting for the other to interpret.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this activity, teams of learners study magnetic fields at four separate stations: examining magnetic fields generated by everyday items, mapping out a magnetic field using a compass, creating model

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

This fun hands-on astronomy activity lets learners explore models of the Milky Way and other galaxies to get a sense of relative distances to other galaxies.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.
