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

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.

In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

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

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

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

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.
