Learners play the role of materials engineers as they test the flexibility of different materials.

Learners construct and launch paper helicopters.

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

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

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

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

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.

Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

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

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

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 model directed evolution by making paper fly. Learners construct and fly paper airplanes.
