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

In this space science activity, learners work together to create a human-powered orrery to model the movements of the four inner planets.

Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.
