Title: Practice Using a Classification Key

Lesson: Nomenclature

Classroom Activity

Purpose:
When a biologist finds a life form that they cannot identify, a classification key is used to determine what the life form is. The classification key is a "road map" that is used to find the scientific name of an unknown organism. The purpose of this activity is to become familiar with using a classification key.
Activity Directions:
Study the diagrams on the following page. We will consider these as "unknown organisms." Determine the scientific and common name of each of these "unknown organisms" by using the key on the next page. For each numbered item, choose between a or b. Decide if a or b more accurately fits the illustration, and then follow the letters accompanying directions. After determining the scientific name of the organism, write the identifying organism's letter in the blank at the right.
Materials Needed:
1. Pencil.
