WATER PURIFICATION MODULE OVERVIEW Funded by the Teacher Quality Program A project of : The State Botanical Garden of Georgia, The GA Museum of Natural History and Georgia 4-H WATER MODULE REVIEW Overview: In this module learners learn how earths ecosystems provide the vital service of purifying water. Through gaming activities and experiments they discover there is a limited amount of water available for a multitude of uses and they examine the watershed on their site. Learners explore their impact on local water resources and come up with a plan to lessen their impact on earths water supplies. A lesson plan is also provided for a stream study. An optional stewardship/service learning project involves safeguarding water resources in their local environment. WATER MODULE Enduring Understandings: Learners will understand that * There is a limited amount of fresh water on planet earth. * Wetlands, some of the most productive habitats in the world, can remove many harmful substances from water and are threatened by destruction due to filling and development. * The area in which surface water flows downhill to one common point is called a watershed. * Any action in a watershed can impact the water quality of that watershed. Essential Questions: What is a watershed? Where does our drinking water come from? How can we measure water quality? Why should we care about the Water Purification Department? Major Concepts: 1. Fresh water makes up only 3% of the water on Earth, usable fresh water is only 1% (97% is salt water). 2. Toxic substances or other pollutants often end up in water. 3. Water cycles through the atmosphere and is purified as it turns from a liquid to a gas and back again. 4. Wetlands, some of the most productive habitats in the world, can remove many harmful substances from water and are threatened by destruction due to filling and development. 5. The area in which surface water flows downhill to one common point is called a watershed. 6. Any action in a watershed can impact the water quality of that watershed. 7. Aquatic ecosystems provide habitat for many organisms, including immature insects. WATER MODULE Each module contains 4 main Lessons as well as a suggested Citizen Science project.

Water falls on land and flows into streams 39 swamps, ponds, lakes and rivers. 40 Water Used by Plants and Animals 41 Land and Water Connections 42 How will we learn about the Water Purification department? Stream Study 43 Threats to the Water Purification Department: Chemical Pollution 44 Threats to the Water Purification Department: Sediment Pollution 45 We need to take care of our water. 46 What can we do to help the Water Purification Department at our club site?
