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

In this physics activity, learners will explore buoyancy.

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

Learn how to make and fly a paper helicopter! This simple activity includes a template (for the copter "blades") and instructions for folding, flying, and testing designs.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

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

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.

In this activity, learners construct paper airplanes that twist and turn.

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

This activity is a hit for family events and all ages—some will finish in 45 minutes; others can go on for hours.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.

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.

Learners cut and fold a paper helicopter from the template in this PDF. They practice twirling the helicopter and observe what happens as they modify their tries.

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

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

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