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

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this optics activity, learners make a simple telescope using two lenses and a cardboard tube. Learners construct the telescope and then calculate its magnification.

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

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

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