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

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

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

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.

Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

In this activity, learners explore clouds and how they form.
