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

Using simple, inexpensive items, learners build and test submarine models.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

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

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.

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

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

Learners investigate how drag affects the falling rate of objects.

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.
