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

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.

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

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

“Exploring the Solar System: Big Sun, Small Moon” is a hands-on activity that explores the concept of apparent size and allows visitors to experience this phenomena using familiar objects—a tennis bal

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 explore how distance can affect the way we perceive the size of an object.

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

In this online interactive challenge, learners choose items to represent the Earth or solar system, then determine other items to represent the Moon, or Milky Way based on their relative size.

In this activity, learners explore the relative sizes and distances of objects in 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.

This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?

In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

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

In this activity (page 18 of PDF), learners will measure the volume of impact craters created by projectiles of different masses.

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 (page 7 of PDF), learners will identify the general two-dimensional geometric shape of the uppermost cross section of an impact crater.

In this activity (page 10 of PDF), learners approximate the area of the uppermost cross section of an impact crater using a variety of square grids.

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.

In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.
