  1. Stream Study

  2. What is a watershed? http://www.youtube.com/watch?v=f63pwrMXkV4&feature=related

  3. What path does water follow to get to the Potomac River from Fairview? FAIRVIEW Toms Run Little Conococheague Creek Potomac River

  4. When precipitation falls on Fairview, where does it go? • Toms Run • Little Conococheague Creek • Potomac River • Chesapeake Bay • Atlantic Ocean

  5. FOCUS QUESTIONWhat are the types and sources of water pollution and how do they impact the health of the Chesapeake Bay Watershed? Chesapeake Bay Waterman Singing About The Bay

  6. Scientists test water to determine the health of the water. Today as scientists, we will conduct several tests to determine the health of Toms Run.

  7. Turbidity: How cloudy is the water? (JTU) 150 80 40 20 10

  8. Dissolved Oxygen(Measured in parts per million – ppm)

  9. pH

  10. Benthos are an important part of the food chain. They play a critical role in the natural flow of energy and nutrients. Larger than ½ millimeter (size of a pencil dot) Live under rocks, logs, and in sediment. Includes crayfish, clams, snails, worms, water pennies, stonefly and mayfly nymphs. Macroinvertebrate Collection

  11. Stream Insects & Crustaceans GROUP ONE TAXA Pollution sensitive organisms found in good quality water. 1. Stonefly 2. Caddisfly 3. Water Penny 4. Riffle Beetle 5. Mayfly 6. Gilled Snail 7. Dobsonfly GROUP TWO TAXA Somewhat pollution tolerant organisms can be found in good or fair quality water. 8. Crayfish 9. Sowbug 8 8 2

  13. Turbidity: How cloudy is the water? (JTU) 150 80 40 20 10

  14. pH

  15. Dissolved Oxygen(Measured in parts per million – ppm)

  16. Making Sense of Data • Carefully examine the results of the water quality tests and the macroinvertebrate survey. • Based on your observations, what can you conclude about the health of Toms Run? Include in your response • A brief conclusion about the health of Tom’s Run. • Three observations from the data that support your conclusion.

  17. Extending Our Thinking What can you do to help reduce the amount of pollution that goes into the Chesapeake Bay?
