Classification Essential Questions
Directions: The following classification questions give you the opportunity to reflect/review on what
you know. It is made of only key points and questions. Simply explain section 1, 2,3 and 4 as you
learn them in class. You can write your responses next to each question.
Unit Story: You should be able to tell the following story by the end of the unit…….
Classification schemes reflect orderly patterns and observable distinctions among objects and
organisms. One of the most general distinctions among organisms is between plants and animals.
Biologists consider an organism's structural features more important for classifying organisms
than behavior or general appearance. Geologists classify earth materials based upon structure.
Chemists classify matter based upon structure. Classification systems may change as science
develops new knowledge.
