  1. Stream Day

  2. Purpose: Stream Day was designed to learn about environmental awareness in the Little Connoquenessing Creek.

  3. Goal: Using inquiry based methods to teach students how to collect data and use it to determine human impact on a watershed.

  4. What is Stream Day? • Each team is scheduled one day to work outside to collect data from 6 stations. • Each station is conducted by upperclassmen and Seneca Valley staff. • This is an outside classroom. You are expected to follow all directions given by your instructor. • Any behavioral issue will result in you coming inside for the remainder of the day.

  5. Station 1 – Perch Dissection • First, upperclassmen help students identify external structures of a perch. • Next, upperclassmen assist with the dissection of the perch so internal anatomy can be observed and properly identified. • Finally, students summarize how the perch has adapted to aquatic life based on the structures examined.

  6. Station 2 - Stream Velocity • Students enter the stream to measure depth and width of the stream. • Students will use fishing bobbers to calculate the velocity of the water at various locations.

  7. Station 3 – Macroinvertebrate Collection and Identification • Students enter the stream with kick nets to collect and identify macro-invertebrate life. • Students can use data to determine health of the stream.

  8. Station 4- Water Quality/Chemistry • Students work in a small group to test pH, nitrate levels, phosphates, dissolved oxygen, turbidity, and temperature. • Small samples of water are collected to be tested for such chemicals

  9. Station 5 – Crayfish ID • Students will use a key to identify different species of crayfish • Determine gender of crayfish

  10. Station 6 – Float My Boat • Students are given the opportunity to design a water craft to transport a rock down a specific length of the stream. • Upperclassmen will assist with keeping time/records. • Top groups will receive prizes.

  11. Expectations • Come prepared: • Appropriate dress; follow dress code • No flip-flops • Pack a lunch or purchase in cafeteria • Bring a water bottle • Stay with your assigned group • No electronics outside • Bring dry clothes/shoes to change • Bug spray/sunscreen/hats • Be respectful of your station leader

  12. Timeline • Six Stations • 1 8:45-9:30 • 2 9:30-10:15 • 3 10:15-11:00 • Lunch 11:00 – 12:00 (back to HR) • 4 12:00-12:45 • 5 12:45-1:30 • 6 1:30-2:15 (back to HR)

  13. Macroinvertebrates Group researches the following items : • Define grouping of macros: predators, grazers, shredders, collectors

  14. 2. Determine Pollution Tolerances: 3. Classify class data as acceptable /unacceptable All information used to examine River Continuum
