This PowerPoint presentation is the second of four in a unit titled, "Comparing Living Things", which includes the lessons, "Is It Living or Nonliving?", "How Are Living Things Classified?", "How Are Animals Classified?", and "How Are Plants Classified?". These are all based upon information from the fifth grade Scott Foresman Science textbook. This particular PowerPoint presentation contains fifteen slides that present students with information about how organisms are classified, the five kingdoms, how the kingdoms are further divided, and scientific names. This PowerPoint presentation, as well as the others in the series, were designed by Marie Wimsett.
