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.

In this standards-aligned unit, students learn about Mars, design a mission to explore the planet, build and test model spacecraft and components, and engage in scientific exploration.

Launch rockets, build a hovercraft, create a winning science fair project and more! These science, technology, engineering and math activities are fun for kids, adults and the whole family.

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.

Students use math to investigate a real-life asteroid impact.

Students learn to read, interpret and compare “heat map” representations of Earth science data.

Using the fundamental criteria for life, students examine simulated extraterrestrial soil samples for signs of life.
