In this illustrated problem set, students use pi to compare the sizes of Mars landing areas, calculate the length of a year for a distant solar system object, measure the depth of the ocean from an airplane, and determine the diameter of a debris disk.

Students predict the scale of our solar system and the distance between planets, then check their answers using fractions.

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

Students learn about cloud types to be able to predict inclement weather. They will then identify areas in the school affected by severe weather and develop a solution to ease the impacts of rain, wind, heat or sun.

In this illustrated math problem, students use the mathematical constant pi to find the "habitable zone" around a distant star and determine which of its planets are in that zone.

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 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.

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 pi and data from Mars orbiters to calculate how much of Mars was covered by a giant dust storm.
