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 environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

Plants need nutrients to grow. This is why we apply fertilizers to grass and food crops. In this activity, learners will explore how fertilizers can affect lakes and other bodies of water.

In this activity (on pages 36-39), learners make a model of a watershed out of paper, then run water down the mountain to simulate how rainfall and pollution affect watersheds.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

Learners take on the role of environmental engineers as they design water filters.

In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

This marine biology activity (on pages 11-17) introduces learners to kelp (seaweed) forests that grow in the ocean and are home to many species of sea animals.

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.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

Millions of organisms can live in and around a body of water.
