Learners develop an understanding of air pressure in two different activities.

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, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

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.

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

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

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

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