In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

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

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

"Molecules in Motion" explores how materials behave and change in a vacuum.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In this activity, learners construct a simple air pressure launcher for paper rockets.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
