Students balance circular and gravitational forces to create a model of an object in orbit.

Students study rocket stability as they design, construct and launch paper rockets using soda straws.

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

In this video lesson, students learn to design, build and launch paper rockets, calculate how high they fly and improve their designs.

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 develop spreadsheet models that describe the relationship between the mass of a spacecraft using electric propulsion, the force acting on the spacecraft, and its acceleration.

Students design and build a shock-absorbing system that will protect two "astronauts" when they land.

Students use advanced algebra concepts to determine the next opportunity to launch a spacecraft to Mars.

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.
