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, pairs of learners model how scientists use craters to determine the ages of lunar surfaces. One partner keeps time while the other creates a painting for the other to interpret.

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.

"Exploring the Solar System: Craters" is an active, hands-on activity that demonstrates how craters form, and what they can teach us about the history and composition of planets and moons.

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 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.

Exploring the Solar System: Solar Eclipse” is a hands-on activity demonstrating how the particular alignment of the Sun, Earth, and Moon can cause an eclipse.

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.

This fun and simple hands-on astronomy activity lets learners create 3D models of the Earth, Moon and Sun to demonstrate solar and lunar eclipses.

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

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 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.

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

In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine

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.
