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 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.

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 design and build a solar hot water heater and see how big a temperature change they can get.

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

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

This white-board animation video series explains key concepts about Earth science, missions and climate change.

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