There are three clusters of lessons in //Watery Earth//, listed below. The lessons listed in red are free to download once you enroll in the pilot program and receive a password. After you enroll, our Lending Library will send the other materials you'll need to try out the lessons in a classroom. These include a mini-kit of science materials and hardbound //Student Reference Books// for the unit.

To enroll in the pilot, you'll need to complete a Lending Library Agreement. Basically you tell us where to send the materials, and you agree to return the non-consumable materials and //Student Reference Books// when you are finished or to pay for them. The pilot is completely free as long as you return the non-consumable materials and books to the Lending Library (we pay postage). To find out more, go to the Sign Up for a Pilot page.

To learn more about the unit and the pilot lessons, you can view or download a "Unit Summary and Online Pilot Background" for //Watery Earth// (no password needed).

After you have a password, you can **download free lessons (click here)** You will need [|Adobe Acrobat Reader] on your computer to read the lessons after you download them.

Once you've started using the lessons, you can converse with Science Companion experts and other pilot teachers by using the Discussion tab on this page.

Students experience water with “fresh” eyes (and other senses). They learn that water is a natural resource that is essential for life and explore ways that a variety of organisms use water. They compare their water uses with their water needs and gain an appreciation for their household and community water systems.
 * Cluster 1: Water is a Resource**
 * Lesson 1: The Wonder of Water
 * Lesson 2: Exploring Who Uses Water
 * Lesson 9: Water In, Water Out
 * Lesson 10: Considering Water Wants and Needs

Students explore what might happen to a drop of rain after it falls to Earth. They learn that most of Earth’s water is located in surface water, underground, in glaciers and polar ice caps, and in the air, and that water circulates through these locations via the water cycle. They create a model of the water cycle to observe some of its basic mechanisms in action.
 * Cluster 2: Water Follows a Cycle**
 * Lesson 3: Following a Drop of Water
 * Lesson 4: Learning About Surface Water
 * Lesson 5: Learning About Groundwater
 * Lesson 6: Learning About Frozen Water
 * Lesson 7: Learning About Water in the Air
 * Lesson 8: Modeling the Water Cycle

Students learn how wise choices can help them conserve water and keep it clean. They take a “Pollution Walk” on school grounds, discuss ways to prevent pollutants from entering the water supply, and investigate ways to clean polluted water. They read, discuss, and compare real-life case studies related to conservation and pollution. They take part in a culminating project in which they choose an issue pertaining to protecting water resources, investigate the issue, and then take action to positively impact that issue.
 * Cluster 3: Taking Care of Water Resources**
 * ** Lesson 11: Conserving Water at Home **
 * ** Lesson 12: Walk the Talk - Looking for Pollution **
 * ** Lesson 13: Investigating a Way to Clean Water **
 * ** Lesson 14: Water Resources Case Studies **
 * Lesson 15: Protecting Water Resources Project
