In this challenge, learners make a helium balloon hover in one spot and then move it through an obstacle course using air currents.

In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

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.

In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.
