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.

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.

In this illustrated math problem, students use pi to calculate how much water could be contained within a cloud.

In this illustrated math problem, students calculate the percent by which Jupiter's Great Red Spot shrank between 1979 and 2018.

In this illustrated math problem, students use the mathematical constant pi to calculate the amount of energy put out by a laser to determine if it can explode an ice sample for analysis.

Students create a scale model of the solar system using beads and string.
