In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

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.

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

Discover how a refracting telescope works by making one from scratch using common items. This telescope won't have a tube so the learner can see how an image is formed inside the telescope.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

This hands-on astronomy activity lets learners hunt for different objects in the night sky that contribute to stellar and planetary formation, using a Treasure List.
