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 construct a simple air pressure launcher for paper rockets.

In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

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.
