- 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.
- Students obtain aerial photos of the study site, and/or conduct a land use survey on foot.
- Students complete water quality study at two different sites, compile and discuss results.
The Basics: Land Use & Water Quality
Students will know how land use affects water quality and be able to compare results from two different types of aquatic ecosystems.
- Measuring tape
- Thermometers (air and water)
- Ping pong or tennis ball
- 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
