Changing Hudson Project

The Changing Hudson Project curriculum was developed by scientists and educators at Cary to help students understand how the Hudson River changes over time. By collaborating with teachers, scientists, and management agencies, the curriculum has grown to include a wide range of topics that engage students with visualizations, readings, investigations, and actual scientific data.

The Basics: Land Use & Water Quality

Objectives

Students will know how land use affects water quality and be able to compare results from two different types of aquatic ecosystems. 

Lesson Overview
  1. Students determine which aquatic ecosystems to study (one with 0-10% impervious surfaces, and one with more than 30% impervious surface) and create hypotheses about their water quality based on observed land use. 
  2. Students obtain aerial photos of the study site, and/or conduct a land use survey on foot. 
  3. Students complete water quality study at two different sites, compile and discuss results. 
Time: 
Two 45-minute lessons
Setting: 
Classroom, aquatic ecosystem
Materials
  • Metersticks
  • Measuring tape
  • Thermometers (air and water)
  • Ping pong or tennis ball
  • Stopwatch
  • Waders or appropriate shoes
  • Dissecting trays, tweezers, nets to observe benthic material (optional)
  • Test kits for DO, phosphates, nitrates, pH, chloride and other appropriate tests
  • Goggles, gloves
  • Data sheets-separate sheets for ponds/lakes, streams/rivers, macroinvertebrates and water chemistry
