In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners discover how NASA engineers develop experimental aircraft.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this activity, learners will engineer three different parachutes to test how well each one works.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

In this activity, learners investigate passive solar building design with a focus solely on heating.

Learners act as engineers and design mini submarines that move in the water like real submarines.

In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.
