Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

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.

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

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

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.
