During the first half of each spring semester students in a sophomore-level Biology class (BIO 250) gather water quality data, including flow rates, E. coli concentrations, and more. These data are used to track changes in water quality over time. In the second half of this class students split up into research groups to plan, implement, and analyze data focused on a particular research topic. Past groups have done projects that include antibiotic resistance in stream bacteria, heavy metals in near-stream soils, effect of invasive plants on soil chemistry, influence of a feral cat population on local bird abundance, nutrient runoff from golf courses, etc. A list of the projects done in 2018 can be found here.
