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

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

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 about neuron/target muscle recognition (page 44 of the PDF), learners arranged in two rows facing away from each other use string to simulate neural development.

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.

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

In this fun group activity involving music and movement, learners are introduced to the idea that many insects walk by using their legs to create "alternating triangles." Learners sing the "Ants Go Ma

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?

This activity (located on page 3 of the PDF under GPS: Farm Animals Activity) is a full inquiry investigation into raising livestock.

In this engineering activity, learners design their own board games.

In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.

In this activity, learners role-play the part of lake inhabitants and the aquatic exotics who displace the native species.

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

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

In this outdoor game, learners play the roles of gray or red squirrels gathering and storing a supply of food in "fall" and recovering enough of them to survive the "winter." Learners carry bags repre

In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

Students design and build their own parachutes in this hands-on engineering project.
