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.

In this illustrated math problem, students use the mathematical constant pi to determine the force observed by a hydrogen ion trapped in Earth's magnetic field.

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

Students use satellite and rover images to learn about the various features and materials that cause color variation on the surface of Mars, then create their own “Marscape.”

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

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

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

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