In this activity, learners confront their perceptions of gravity in the solar system.

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

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 parallax, a method used to measure distances to stars and planets in the solar system.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

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

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

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.
