Students build a rubber-band-powered rover that can scramble across the room.

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

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

Students play a strategy card game that requires them to use problem-solving to successfully explore the Moon and Mars.

Students will design, build and test a crew exploration vehicle, or CEV, to carry astronauts to Mars – meeting size, mass and payload requirements.

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

Students work in teams employing an iterative design process to design and build a water filtration device using commonly available materials.

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