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 multi-part activity learners examine non-point water pollution.

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

This is a comprehensive lesson plan on page 85 for a group cleanup trip to a local beach, lake or stream. Learners keep track of the types and amounts of trash picked up and analyze this information.

In this activity on page 60, learners examine and simulate wildlife entanglement by experiencing what it might be like to be a marine animal trapped in debris.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

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.

In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

In this game, learners match descriptions of marine debris (shoes, batteries, paper towels, etc.) to images of these items.

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

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

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 (on pages 29-35), learners examine water pollution and filtration.

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 activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

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