Abstract	Mollusks, such as mussels and snails, are a great group to noodle because they are prevalent in banks and bottoms of river basins and in sandy beach habitats. Furthermore, their shells are easy to come by and safe to handle. There are six classes within the phylum Mollusca. In the activities described in this article, the authors focus on the gastropod (e.g., snails) and bivalve (e.g., mussels) classes. Bivalves serve as good water-quality indicators due to their intolerance of wastewater treatment effluent and other anthropogenic (human-introduced) pollution sources. Mollusks play important roles within their ecosystems, but degradation of natural habitat, decreasing water quality, and increasing artificial structures contribute to the decreasing prevalence of freshwater species. In the two activities the authors describe in this article, designed for middle or high school life science or biology classes, students noodle bivalves and gastropods from a covered container, determining organism density as number per square meter and catch per unit effort. Students analyze their results and learn about using species as indicators of reduced habitat quality. (Contains 2 figures and 3 online resources.) (ERIC).
