Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

Straw Rockets
Source Institutions
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.

Toasty Wind
Source Institutions
In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

Balloon Car
Source Institutions
Build a car that runs on air. Using household materials, experiment with the power of air to create thrust powerful enough to move a homemade car.

Hot Stuff!: Investigation #3
Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

Turning the Air Upside Down: Convection Current Model
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.

I Can't Take the Pressure!
Learners develop an understanding of air pressure in two different activities.

Turning the Air Upside Down: Warm Air is Less Dense than Cool Air
Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

Dunk and Flip
Source Institutions
Learners complete two simple experiments to prove the existence of air and air pressure which surround us.

A Pressing Engagement
Source Institutions
In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

Balloon in a Bottle
Source Institutions
In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.

How Do Probes Get To Space?
Source Institutions
Investigate how force and thrust work to propel rockets into outer space. Build a rocket: a blown-up balloon taped to a drinking straw threaded through some string.

Stadium Seat Science
Source Institutions
Take the two-straw challenge and discover how pressure affects vacuums! In this activity, learners experiment with drinking through one and two straws, comparing the amount of liquid they can drink.

Does Air Weigh Anything?
Source Institutions
The demonstration/experiment provides quick proof that air has mass.

Go with the Flow
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.

Painting a Picture with Air
Source Institutions
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.

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

If Hot Air Rises, Why is it Cold in the Mountains?
Source Institutions
This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

As Light as Air
Source Institutions
Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.
