Students code microcontrollers to send and receive radio signals, simulating communications between Earth and spacecraft.

Students predict the scale of our solar system and the distance between planets, then check their answers using fractions.

Students explore the science behind an intriguing planetary feature by creating saline solutions and then observing what happens when the solutions evaporate. Now updated with findings from Mars!

Students learn to describe meteorites and rocks using candy bars as familiar models.

Students modify a paper cup so it can zip down a line and drop a marble onto a target

Whip up a moon-like crater with baking ingredients as a demonstration for students.

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.

Students build their own comet models using craft materials.
