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 work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

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 explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

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