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

In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

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.

In this online game, learners attempt to send a rocket ship to various targets. Learners can adjust the angle and thrust of the rocket before it is launched.

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.

Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.

In this activity, young learners will learn about moon phases using materials found at home. This activity is adapted using play dough and cups to avoid food allergens and waste.

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, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.

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

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.

Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.

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