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 three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this nighttime, outdoor activity, learners keep a record of what they see in the sky by drawing constellations, the Moon, and making note of the weather and conditions each day.

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

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

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

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

This fun hands-on astronomy activity lets learners use star maps (included) to find constellations and to identify stars with extrasolar planets (Northern Hemisphere only, naked eye).

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this craft activity, learners create a string of cut-out moons and stars.

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 will measure the length of their shadow from the Sun and compare it three to four months later.

Through a series of simple body movements, learners gain insight into the relationship between time and astronomical motions of Earth (rotation about its axis, and orbit around the Sun), and also abou

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

In this activity, learners model ancient lunar impacts using water balloons.
