This whiteboard video describes how "radioisotope power" allows many spacecraft, such as NASA's Curiosity rover on Mars, to stay powered while traveling through space and exploring other planets.

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.

Students build a model that demonstrates an important contributor to sea-level rise – how water volume increases when the temperature of the water increases.

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 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.
