In this lesson, students use their knowledge of moon phases to build a calendar they can use to find out when and where to see each phase of the Moon throughout the year. Calendar for 2022 now available for download!

Students will learn about the expanding universe and the redshift of lightwaves, then perform their own calculations with a distant supernova.

Students use the Danjon Scale of Lunar Eclipse Brightness to illustrate the range of colors and brightness the Moon can take on during a total lunar eclipse.

In this engineering challenge, students must stay within design limitations while creating a balloon and gondola system that can descend or ascend at a given rate or maintain its altitude.

Students use a paper plate to make a model that explains why lunar eclipses don’t occur during every full moon.

Explore space and science activities that students can do with NASA at Home, including video tutorials for making rockets, Mars rovers, Moon landers, and more.

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 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.

Quickly and easily model how colors reflect, absorb, and interact with each other in the classroom or online using your computer’s camera.
