In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In "Exploring the Universe: Exoplanet Transits," participants simulate one of the methods scientists use to discover planets orbiting distant stars.

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 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 activity, young learners explore the basic shapes of constellations by making their own scope out of a cardboard tube and paper with pinpricks.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

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.

In this activity, learners build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.
