  5. 5. Introduction In this unit, we are studying The World Around Us, focusing on the Bronx River. The Bronx River is approximately 24 miles long and flows from Westchester County, from north to south through the Bronx, and empties into the East River. In the Bronx, the River separates the East Bronx from the West Bronx. Our investigation was an observational study of the biotic and abiotic factors of the Bronx River ecosystem. We made observations and collected data at the Gun Hill Road Canoe Launch of the Bronx River. Using our data, we will design controlled laboratory experiments to investigate questions and issues that we uncover from analyzing the data that was collected.
  6. 6. LEARNING TARGETS  I CAN EXPLAIN HOW BIOTIC AND ABIOTIC FACTORS ARE CONNECTED IN THE EVNIRONMENT  I CAN DEVELOP TESTABLE QUESTIONS ABOUT THE LOCAL ENVIRONMENT
  7. 7. THE DATA WE COLLECTED WATER TESTING  pH  Dissolved Oxygen  Temperature  Materials Used: Vernier Probes AQUATIC MACROINVERTEBRATES  Identification of macroinvertebrates in the River  Materials Used: Kick nets, waders, macroinvertebrate identification guide
  8. 8. THE DATA WE COLLECTED SOIL TESTING  Soil Texture  pH  Materials Used: Soil pH Test Kit TERRESTRIAL MACROINVERTEBRATES  Identification of macroinvertebrates in the soil  Materials Used: Spade, sweep nets, macroinvertebrate identification guides
  9. 9. THE DATA WE COLLECTED WORM COUNT  Raised worms from the soil  Identified and counted worms  Materials Used: PVC quadrat, mustard slurry, worm identification guide.
  10. 10. OUR RESULTS Test Measurement Water Temperature 11.5 °C Dissolved Oxygen 7mg/L River pH 7.2 Soil Quality Silt and sand Soil pH 8.0 Macro Invertebrate Quantity Flat Worm (2.5 cm – 15 cm) 5 Circular Worms (3 cm – 7.5 cm) 4 Centipede N/A Slug N/A Sowbug N/A Round Worm N/A Beetle N/A Leaf Hopper N/A
  11. 11. WHAT’S NEXT………… Design controlled experiments to investigate issues and questions uncovered by our data:  Why are there more worms on one side of the river than the other?  What is the effect of changes in temperature, soil pH and soil quality on terrestrial macroorganisms?  What causes changes in the pH level of the river?  What other nutrients are important to river health?
  12. 12. QUESTIONS FOR FUTURE INVESTIGATION  What is the biodiversity of macroinvertebrates in the Bronx River?  Look for macroinvertebrates at different locations in the Bronx River  What are ideal soil conditions for macroinvertebrates around the Bronx River?  Additional soil testing  Test multiple locations  What is the general health of the Bronx River?  Comparison of nutrient levels and evidence of pollution to species abundance and biodiversity around the Bronx River.
