  • 7. 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.
  • 8. LEARNING TARGETS
    I CAN EXPLAIN HOW BIOTIC AND ABIOTIC FACTORS ARE CONNECTED IN THE EVNIRONMENT
    I CAN DEVELOP TESTABLE QUESTIONS ABOUT THE LOCAL ENVIRONMENT
  • 9. 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

  • 11. 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

  • 13. THE DATA WE COLLECTED
    WORM COUNT
    Raised worms from the soil
    Identified and counted worms
    Materials Used: PVC quadrat, mustard slurry, worm identification guide.

  • 15. OUR RESULTS
  • 16. 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?
  • 17. 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.
