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

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 video lesson, students learn to design, build and launch paper rockets, calculate how high they fly and improve their designs.

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

Students construct balloon-powered rockets to launch the greatest payload possible to the classroom ceiling.

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

In this engineering challenge, students must stay within design limitations while creating a balloon and gondola system that can descend or ascend at a given rate or maintain its altitude.

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.

These 60-second videos answer some of the most frequently asked questions about our planetary neighbor, Mars, and the spacecraft that explore it.
