In this 19-lesson, 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.

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 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

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.

Students use the mathematical constant pi to determine what fraction of a signal from Voyager 1 – the most distant spacecraft – reaches Earth.

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.

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

Students use mobile devices to measure the impact a solar eclipse has on the energy received at Earth’s surface.

This animated video shows how NASA's Cassini spacecraft at Saturn uses radio science to "peer" beneath the surface of the hazy moon Titan and study its mysterious lakes.
