There are a number of websites with many ideas for incorporating aquatic macroinvertebrates into the classroom. Here are some suggestions:

Aquatic Macroinvertebrate Lesson Plans, Utah State University. Grades K-12 (mostly K-6), field and classroom activities.

Coloring book from the Utah State University site. Grades K-2.

Macroinvertebrate Mayhem, Minnesota Department of Natural Resources. Grades 3-5, classroom or playground.

Feeding the Hungry Stoneflies, University of Montana. Grade 5. Classroom (optional field trip).

Wyoming Stream Team manual, Teton Science School. Grades 4-12, many suitable for MS and HS, field activities. Biological monitoring begins on page 96.  Information about Wyoming Stream Team can be found at

Simulation of Cutthroat Trout Life History, University of Montana. Grades 5-12, classroom. (This one isn’t about macroinvertebrates, but it is aquatic.)

Water What-ifs: Water Quality and Aquatic Macroinvertebrates, North Carolina State University. Grades 6-12, field and laboratory (includes experimental manipulation of water quality).

Biodiversity: Diversity in a Leaf Pack - Pathways Project, an NSF funded project with Colorado State University and partners. Grades 6-12, field and lab. This semester-long unit includes learning progressions and 13 lessons. The pdf is available here.

Save our Streams, Izaak Walton League. Intended for adults, but several good resources, including a video on aquatic macroinvertebrate identification.

If you are interested in learning about professional water quality monitoring in Wyoming, check out THE WYOMING STREAM INTEGRITY INDEX (WSII) – MULTIMETRIC INDICES FOR ASSESSMENT OF WADEABLE STREAMS AND LARGE RIVERS IN WYOMING, by E.G. Hargett, Wyoming Department of Environmental Quality, Water Quality Division, 2011.

WyoBio, the Wyoming Biodiversity Citizen Science Initiative, has maps of watersheds, gauging stations with links to USGS data, information on impaired waters, climate data, and many other geographic and biologic data sets that may be useful for classroom research. In addition, WyoBio accepts observations of organisms, including invertebrates, and encourages classes to contribute data.
