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

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.
