In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.
