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

In this illustrated problem set, students use pi to reveal the size of a planet outside our solar system, find out how much helium is raining out from Jupiter's cloud tops, locate a seismic event on Mars and study an interstellar object detected in our so

This lesson uses stacking cubes as a way to graph precipitation data, comparing the precipitation averages and seasonal patterns for several locations.

These 60-second videos answer some of the most frequently asked questions about our planetary neighbor, Mars, and the spacecraft that explore it.

In this illustrated math problem, students use pi and data from the Kepler space telescope to find the size of a planet outside our solar system.

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.

When Mercury passes in front of the Sun, how much sunlight is lost on Earth? Students use the mathematical constant pi to find the solution in this illustrated math challenge.

Students use the mathematical constant pi to measure the approximate size of the shadow that will fall on Earth during a total solar eclipse.

In this activity, students learn how light and energy are spread throughout space. The rate of change can be expressed mathematically, demonstrating why spacecraft like NASA’s Juno need so many solar panels.
