Classification One Big Mess!
Three domains, 5 (or 6) Kingdoms Let s make a big chart. Cell type? Chromosomes? Ribosomes? Cell wall or not? Made of what? Unicellular or multicellular? Autotroph or heterotroph? Muscles and nerves? Let s practice
SC.912.L.15.6: Discuss distinguishing characteristics of the domains and kingdoms of living organisms. SC.912.L.15.4: Describe how and why organisms are hierarchically classified and based on evolutionary relationships SC.912.L.15.5: Explain the reason for changes in how organisms are classified.
Levels number Scale standards 4 -Compare and contrast the characteristics and examples of the three domains -Apply the characteristics to an unknown organisms, to categorize into a Domain and Kingdom -Design/Invent a classification system based on real or imaginary organisms 3* -Discuss distinguishing characteristics of the domains and kingdoms of living organisms -Explain the reasons for changes in how organisms are classified -Describe how and why organisms are hierarchically classified and based on evolutionary relationships 2 -Identify the domain based on a list of distinguishing characteristics -Identify the kingdom based on a list of distinguishing characteristics 1 -Define: Domain, Kingdom, Organism, Taxonomy, Archaea, Bacteria, Eukarya, -List the domains and kingdoms
