Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

In this engineering activity, young learners investigate multi-level buildings.

In this activity, learners engineer a paper helicopter that spins to the ground when dropped.

In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

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

No glue is needed for learners of any age to become marshmallow architects or engineers.

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

In this project, students explore how levers work, by making a puppet with moving limbs.

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.
