Using real data from NASA’s GRACE satellites, students will track water mass changes in the U.S.

Students will use the engineering design process to design, build, test and improve a model satellite intended to investigate the surface of a planet.

Students build a rubber-band-powered rover that can scramble across the room.

Students learn about scale models and distance by creating a classroom-size Earth-Moon system.

In this challenge, students will program a rover to use a color sensor on several rock samples, allowing them to simulate how the Mars Curiosity rover uses it's ChemCam instrument to analyze light emitted from geological samples on Mars.

This board-game activity teaches students the process of design, engineering and technology for a mission to Mars.

What is sea-level rise and how does it affect us? This "Teachable Moment" looks at the science behind sea-level rise and offers lessons and tools for teaching students about this important climate topic.

In this illustrated problem set, students use pi to determine the size of a Mars dust storm, estimate the water content of a rain cloud, gauge how much Jupiter's Great Red Spot has shrunk and calculate the strength of a laser used to explode ice samples.

In this illustrated math problem, students use pi and data from Mars orbiters to calculate how much of Mars was covered by a giant dust storm.
