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 devices from rubber bands to test for invisible air pollutants.

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

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

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

Students design and build their own parachutes in this hands-on engineering project.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

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 design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

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

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.

From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.

In this activity, learners make acid/base indicator paper, place the indicator paper on an anthill, disturb a bunch of ants, and then observe what happens!

By participating in a seed scavenger hunt, learners examine many adaptations of seeds, including how many seeds a plant makes, how those seeds travel to new locations, and what protects them from pred
