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.

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

Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

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

Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

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.

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

Learners build devices from rubber bands to test for invisible air pollutants.

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 build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

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.

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

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