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

In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails.

In this activity, learners build a nanorover model using styrofoam meat trays and a balloon.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

In this board game, learners explore the origins of meteors, meteoroids, and meteorites as well as the their characteristics and importance. They also discover some misconceptions about meteors.

Space Guess Quest is a fun game that encourages participants to identify the many types of objects in space, from human-made spacecraft to nebulas, galaxies, stars, and worlds.

In this activity, learners drop impactors onto layers of graham crackers!

In this activity, learners craft their own model of a comet on a stick to make it fly around the room.

In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

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

Make impact craters with marbles (or rocks or washers) in a container of flour. Find out what you can learn about your "comets" by the craters they make.

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

In this activity, learners will imagine the challenges and opportunities of asteroid mining.

In this activity, learners work in teams to investigate the composition of unseen materials using a variety of tools.

In this activity, learners model how the Moon's volcanic period reshaped its earlier features.

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 (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.

"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.
