In this 2 part lab, students learned about watersheds, human impact on watersheds, and how macroinvertebrates can serve as bioindicators of a healthy watershed. On day 1, students used Mini Enviroscapes to learn about how water flows over a watershed. Students were asked to critically think about human pollution that could make its way into the watershed and to see patterns that their actions cause while engaging with the enviroscape. Then they placed different “pollutants” on the Enviroscape to visualize how humans can impact the watershed. Finally, students mapped their own watershed with the help of https://modelmywatershed.org/ . On day 2, students were given leaf packs from a local creek and pond to look for macroinvertebrate indicator species. Indicator species were sorted into levels to assess the health of a body of water. Students then connected the knowledge of how human pollution flows into these waters with the organisms. To finalize the activities, students reflected with a Flipgrid to collect evidence of being a global citizen and how critical thinking can help them keep a watershed cleaner.
