In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

In this quick and easy activity, learners build an air cannon "drum" and see what happens when they "shoot" puffs of air at different targets.

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.

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.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

What keeps bubbles and other things, like airplanes, floating or flying in the air?

In this activity, learners will create unique rockets. Each rocket will be powered by air as the learner will blow into a straw and watch their rocket fly.

In this activity about states of matter, learners get to witness firsthand the awesome power of air pressure. They watch as an ordinary soda can is crushed by invisible forces.

In this activity, learners engineer a paper helicopter that spins to the ground when dropped.

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

In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

Students design and create their own air-powered rockets, in this hands-on activity.

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

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

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

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.

Most of the time, we don't have to think about breathing. In fact, you're probably breathing right now without thinking about it!

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