In this challenge, students will use a model robotic arm to move items from one location to another. They will engage in the engineering design process to design, build and operate the arm.

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

In this simple engineering design lesson, students turn a piece of paper into an aircraft wing and then try to improve upon their design.

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.
