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.

In this challenge, students will program a rover to use a color sensor on several rock samples, allowing them to simulate how the Mars Curiosity rover uses it's ChemCam instrument to analyze light emitted from geological samples on Mars.

Students design, build and program a robotic “super crawler” to transport a payload from a starting position to a target launch pad, deliver the payload in an upright position and return the robot to the starting point.

In this challenge, students must program a rover to get from point A to point B on a map without driving across any of the craters located between the two points.

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

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

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