In this activity, learners model the gravitational fields of planets on a flexible surface.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners investigate the Moon's infancy and model how an ocean of molten rock (magma) helped shape the Moon that we see today.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

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, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.

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.
