In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.

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.

In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

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

Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

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

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.

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

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

In this activity, learners discover a trick to release the air out of a balloon without popping it.

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.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

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.

Learners test two jars containing soil, 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.

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.
