Create a painting by blowing air out of a straw. Push liquid acrylic paint around on some watercolor paper by aiming short bursts of air onto the paint puddle.

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

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.

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

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.

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

In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

Students design and build their own parachutes in this hands-on engineering project.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

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.

Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.
