Video Analysis

    Watch this video to see how scientist survey biodiversity in streams and how this varies with stream flow and water quality. https://youtu.be/cYCkuJ5bHTk Part A: In this lab we will be simulating the kick and sweep method of sampling macro invertebrates as seen here in this video (we won't actually be going to the stream).https://youtu.be/SF88w75lAuE below are the macroinvertabrates for your 4 streams (1 page per stream). Follow directions in lab pdf for counting and recording: Note: not all samples are listed in the table. It works best if you classify them with something similar like the larvae with the adults or with a similar species rather than placing it in the other category. Part B: Pharmaceuticals in the Watershed - to complete this section you will need to read these two articles (are pharmaceuticals in your watershed) and (the complicated question of drugs in the water) and http://www.pbs.org/wgbh/nova/next/body/pharmaceuticals-in-the-water/
