The demonstration/experiment provides quick proof that air has mass.

Learners build devices from rubber bands to test for invisible air pollutants.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

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

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

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

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

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

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

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

Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.
