Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

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

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

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

As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up.

This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.

In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.

Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

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

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