Students construct CD hovercraft as a lesson in Newton's laws of motion and friction -- plus an astronaut tie-in.

In this 19-lesson, 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.

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

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

Students will use the engineering design process to design, build, test and improve a model satellite intended to investigate the surface of a planet.

This board-game activity teaches students the process of design, engineering and technology for a mission to Mars.

Youth design and build a model spacecraft to Saturn and share it with the group.

Youth use creativity and problem solving to design and drop a parachute spacecraft.

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