Stream Team

Students wading in a stream to collect macroinvertebrates.
Students wading in a stream to collect macroinvertebrates to use in assessing the health of the stream.
 
Overview: 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.
Grade Level:
5 - 8
Objectives: Students will:
  • 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

Did You Know?

The toe of Carbon Glacier appears dirty as it is covered in silt. Mount Rainier is in the background.

Carbon Glacier, on the north side of Mount Rainier, comes to the lowest elevation of any glacier in the lower 48 states at 3500 feet. It is also Mount Rainier's thickest glacier, one section being nearly 700 feet thick.
