In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.

In this activity, learners will make and launch feather rockets. Lerners will use science process skils such as making predictions and measuring while launching the rockets.

In this activity, learners explore Charles' Law in a syringe.

In this outdoor activity/field trip, learners locate and study plants and animals in several freshwater pond habitats.

In this dramatic activity/demonstration about phase change and condensation, learners place an aluminum can filled with about two tablespoons of water on a stove burner.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

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

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

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.
