In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.

In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.
