Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

This lesson guide includes six simple and quick activities to help learners better understand Bernoulli's Principle.

The demonstration/experiment provides quick proof that air has mass.

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

In this activity, learners make different shapes that hold exactly one mole of gas (air).

This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.

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.

Learners develop an understanding of air pressure in two different activities.
