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 shrink the scale of the vast solar system to the size of their neighborhood.

In this activity, learners discuss how life is defined and conduct a simple experiment, looking for signs of life in three different “soil” samples.

This is a classic exercise for visualizing the scale of the Solar System.
