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

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

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

In this activity (p.5-6 of PDF), learners investigate natural selection. Learners discover that natural selection, which takes place over decades, can lead to altered populations within a species.

In this activity, learners gain a better understanding of how household/school waste breaks down in a landfill. Learners collect trash and then create miniature landfills in 2-liter bottles.

In this activity, learners investigate the impact of oil pollution on the environment and wildlife. Learners use hard-boiled eggs and feathers to understand the damage that oil spills can cause.

This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.

In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.

In this activity, learners explore a bucket of sand and beach objects.

In this activity, learners explore clouds and how they form.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.
