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 engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

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

In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.
