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.

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

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.

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 discover a trick to release the air out of a balloon without popping it.

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

In this trick, learners discover how to stick a straw to the palm of their hand, window door, or anywhere using static electricity.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

In this activity, learners turn an ordinary metal coat-hanger into a (very quiet) musical instrument.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this physics activity, learners will explore buoyancy.

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 explore Charles' Law in a syringe.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.
