Lesson Plan: Classification Biology

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to name and classify organisms and describe the importance of developments in biology to the classification system.


Students will be able to

  • recall the contributions of Aristotle and Linneaus to the study of classification and taxonomy,
  • state the 5 kingdoms as animals, plants, fungi, protists, and prokaryotes,
  • use the binomial system to name organisms according to their genus and their species,
  • describe how organisms can be classified according to their physical appearance (artificial classification) or their evolutionary links (natural/phylogenetic classification),
  • explain the benefits of classifying organisms into groups, including how it allows scientists to identify new species, determine evolutionary links, and predict characteristics of extinct or extant organisms,
  • describe how genetic analysis has led to the 3-domain classification system.


Students should already be familiar with

  • basic ideas of classification in the animal kingdom (e.g., humans are mammals).


Students will not cover

  • the 6 or 7 kingdoms,
  • the process of genetic analysis.
