In this activity, learners explore the relative sizes and distances of objects in the solar system.

In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

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

Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.
