Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

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

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

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.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.

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