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

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.

Students create a presentation for their peers by exploring planets, missions, and asteroids with NASA’s Eyes, a free, web-based interactive.

Students learn how NASA decodes spacecraft data, then students decode their own data to reveal space images.

Students learn about the role of dark energy and dark matter in the expansion of the universe, then make a model using balloons.

In this cross-curricular STEM and language arts lesson, students learn about planets, stars and space missions and write STEM-inspired poetry to share their knowledge of or inspiration about these topics.

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

In this illustrated math problem, students use pi to calculate the distance across a disk of debris around the star Beta Pictoris.
