Freshwater Mussels: Treasures Past and Present

Science, Grades K–12
Time required: 30 to 40 minutes

These little known but ecologically significant animals of Tennessee waters illustrate many topics in the life sciences, including ecology, life cycles, symbiotic relationships, scientific classification, and human uses and impacts upon natural populations, including extinction. Students observe features of mussel shells and infer organism characteristics, and play the “Guess My Name” game with shells.
