Students define the word dichotomous and explain why a dichotomous key is a useful tool in identifying different species. Then they look up words they are unfamiliar with or mollusk reference books so students can learn the names of mollusk parts, which help them through the key. Students also try to figure out what shell they have been given and exchange shells with other students to practice using their dichotomous key.
