In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

In this activity, learn about the cultural stories behind constellations. Then recreate your favorite constellations using marshmallows and toothpicks.

In this activity, learners recreate the lunar phases using the frosting from Oreo® cookies and place the phases in order. Round cream cheese crackers can also be used if cookies are not an option.

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this activity, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.

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

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.

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 and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.

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 imagine what would happen if our Sun were replaced with a black hole.

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

In this activity, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.

This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.

This chocolate chip cookie recipe includes templates for baking night sky constellations of the season right on top! Two templates are included, one for 9pm mid-April, and one for 10pm mid-July.
