Students were given a list of animals (photos included) and were asked to classify the organisms based on the concepts of a dichotomous key. Each student cut out all of the animal photos and organized them into two large groups (ie., One group that has a certain quality, and the second group which does not have the same quality). These made the first two groups of the dichotomous key. From each of the two groups, students worked on one side of the key at a time to divide each group into two other groups (as before) based on one decisive question which would create two more groups. Students continued the process until they were able to get each animal separated into its own group using only one question to classify all of the organisms into a large dichotomous key. This was a time consuming and sometimes confusing task for students, but proved to them that taxonomists must consider all types of information when classifying different organisms that may or may not seem similar to each other.
