In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

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

En esta actividad sobre la exploración e investigación, los aprendices harán ventanas de burbujas.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

In this activity, learners watch a figure "magically" float up through the air.

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.
