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 build a spectrometer using basic materials as a model for how NASA uses spectroscopy to determine the nature of elements found on Earth and other planets.

Students kinesthetically model the mathematics of how NASA communicates with spacecraft.

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 its ChemCam instrument to analyze light emitted from geological samples on Mars.

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 six-part video series walks educators and students through the ins and outs of crafting a science fair project.

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.
