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

In this demonstration/activity, water streaming through holes in the bottom of a suspended soda pop can causes the can to rotate.

In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.

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

Learners follow the template to build and fly a paper helicopter.

In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

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

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.
