Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

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

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

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 explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

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.
