In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

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

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

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.

In this collaborative storytelling activity, learners and caregivers develop a strong story about science and exploration.

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

In this hands-on activity, learners simulate the crashing and smashing of a meteor impact using household cooking supplies.

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

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

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.

In this activity, learners explore how distance can affect the way we perceive the size of an object.
