In this activity, learners drop impactors onto layers of graham crackers! The process models how impacts throughout the Moon's history have broken rocks down into a mixture of dust, rocks, and...

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. The game simulates the pull of gravity...

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution. They will learn that observing instruments, whether telescopes...

In this activity, learners will use Google Sky to observe features of the night sky and share their observations. Learners partake in a "Telescope Treasure Hunt" as they look for...

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...

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. This activity is...

In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF). Learners drop the...

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. Learners use discs of different sizes and view them from at least...
