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.

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 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.

Students gather data on a balloon rocket launch, then create a simple graph to show the results of the tests.

In this activity, students will use sea-level rise data to create models and compare short-term trends to long-term trends. They will then determine whether sea-level rise is occurring based on the data.
