VA SEA 2017 Lesson Plans


This lesson plan provides a hands-on way for students to investigate the impacts of an invasive parasitic nematode which has been targeting the American eel. Students will first “infect” pipe cleaner eels with parasitic nematodes (beads), which will then be used to simulate real-life research efforts through collecting multiple random samples of “eels” and counting the amount of parasites. They will then use this data to calculate prevalence, mean intensity, and mean abundance.
