Unit 7
Chapter Overview
Students learn how taxonomy categorizes all of Earth’s life forms. They learn how to use the standardized taxonomic system that scientists use to categorize organisms based on similarities and differences shared among groups. In addition, the importance of common classification systems is explored in this unit. Students determine and compare characteristics that define the six currently recognized kingdoms. Students analyze data and information regarding characteristics of organisms in order to make predictions and inferences about the classification of living organisms.
Main Ideas
All living organisms are classified into various groups according to similarities and differences.
Misconceptions
Students may think animals and plants are the only living organisms.
Students may think that fungi are plants and that they make their own food.
