In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

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

By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this activity, learners construct a simple air pressure launcher for paper rockets.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

In this activity, learners build water-propelled engines from soft drink cans.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

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.

In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.
