Students wading in a stream to collect macroinvertebrates to use in assessing the health of the stream.
Students investigate the relative water quality of a stream by conducting a simulated bioassessment by sampling aquatic macroinvertebrates (represented by ordinary materials) in order to prepare for a real-life macroinvertebrate survey that will be conducted with the National Parks Aquatic Resources field team at one of Mount Rainier's streams, rivers, or lakes in order to assess the overall health of that body of water.
5 - 8
investigate the role that aquatic macroinvertebrates play in determining water quality
simulate the process of rapid bioassessment of aquatic macroinvertebrates
collect, sort, classify, identify, analyze, and evaluate a sample of materials representing aquatic macroinvertebrates
determine a stream's water quality using a pollution tolerance index based on a sample of aquatic macroinvertebrates
compare the differences between the relative water quality of different samples
