This field investigation will be in collaboration with Eagle Bluff Environmental Learning Center in Lanesboro, MN link to Eagle Bluff. It will include chemical, biological, and physical tests. The chemical tests will include kits where students need to read the directions and then perform the tests. The tests to be performed are dissolved oxygen, pH, and nitrate levels. The biological tests will be observational. The students will look for macro-invertebrates. The physical tests will be inquiry based. The physical tests include temperature, turbidity, velocity, depth, width, & discharge. A drawing of the stream's profile will also be required. The students will need to design a method to find velocity and discharge of the stream with a few simple tools and interpretation of the data previously collected. The students will collect data at the site and then complete a lab report back in the classroom.
