Students are assigned to small groups; each group is assigned one of the four campus watersheds. Referring to the Watershed Management Plan, the PowerPoint, background readings, and the video, groups will assess their watershed regarding pollution, and answer the following questions:
Rubric: For question 1 look for answers that include sediment, toxic chemicals such as pesticides and heavy metals, nutrients such as fertilizers, stormwater runoff, fecal coliform from leaking sewer pipes or animal waste and evidence such as results of water quality monitoring and visual assessments. For question 2 look for answers such as leaking sewer lines, pet waste, car oil tanks, construction runoff, etc.
Option A: Students are assigned to small groups; each group may be assigned one of the four campus watersheds. For the issues and/or solutions from the PowerPoint, and/or from the prior activities:
Option B: Recall the first example of pollution from the PowerPoint. Students at UGA discovered leaking sewer lines that ran under Broad Street. Recall the second example of pollution from the PowerPoint. A major source of fecal coliform in our waterways is dog waste. Both of these types of pollution affect our watersheds here in Athens. Answer the following questions in small-group discussion and/or in writing.
Est. Time 8 minutes (32-40 minutes into class)
Students continuing working with their groups. Students should look up 5 native species that could replace the invasive exotic plant species studied above. Students should answer the following questions in their notebook about the native species.
1. What is the name of the native plant?
2. What invasive exotic plant species do you think it best replaces, and why?
3. If used on UGA’s campus, how could this native species support the health of UGA’s watersheds?
Suggested native plants for students to learn use: American Holly, Trumpet Honeysuckle, Butterfly Milkweed, Virginia Creeper. (currently no pdf of native species)

Writing Prompt: How can the urban environment (UGA campus, your yard, downtown Athens, and shopping centers around the loop) influence the spread of exotic-species and/or help maintain biodiversity and pollinators like bees and butterflies?
