In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this online activity, learners can test their skills at finding constellations in the northern hemisphere's night sky.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

In this activity on page 60, learners examine and simulate wildlife entanglement by experiencing what it might be like to be a marine animal trapped in debris.

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

This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes.

This activity (on pages 23-27) lets learners simulate the work of scientists who take core samples of Earth's rocky layers to determine geological history.

In this activity (on pages 6-11), learners work as a team to investigate how impact craters on Earth, the Moon or other planets take shape and what patterns they make.

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

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 math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.

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

In this online activity, learners see simulations of how processes shape the Earth, and see estimates of how long these processes take.

This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.

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