  1. Classification Objective: TSW explain why scientists organize things into living groups describe Carolus Linnaeus’ classification system name the seven levels of classification differentiate between genus and species LS 5a-c

  2. Levels of Classification • Who lives in Newport News? • Who lives in _____ neighborhood? • Who lives on ____ street? • Who lives in _____ house? • What’s happening to the number of students raising their hands with each question?

  3. Classification • What does this look like? • What can you say about the bars?

  4. KPCOFGS Broadest Requirements Dear King Phillip Came Over For Good Most Specific Requirements Spaghetti

  5. Leave room above to write a caption Domain Kingdom Phylum Class Order Family Genus Species

  6. Why do scientists classify? • Classification – • Process of grouping things • Biology – study of • living organisms • Scientist who studies Biology - • biologists

  7. Why do biologists classify organisms? • Makes them easier to study them • Taxonomy - • Scientific study of how • living things are classified • CarolusLinnaeus - • Wrote descriptions of organisms he observed • Placed organisms in groups

  8. How are items placed in a grocery store? • Write 6 sections/departments that you can find in a grocery store (note page) • 1. Meat Department • 2. Produce Section • 3. Breakfast Food Section • 4. Dairy Section • 5. Household Cleaning Section • 6. Frozen Food Section • 7. Magazine Section

  9. Carolus Linnaeus - • Wrote descriptions of organisms he observed • Placed organisms in groups based on observable features

  10. Linnaeus’ naming system - • Binomial nomenclature(B.N.) • B.N. - Naming system in which each organism is given a two-part name • Bi – • two • Nomial – • Name or terms

  11. Linnaeus’ naming system - • Genus (Good)- • First part of an organism’s scientific name • Always capitalized • Scientific names written in Latin • Very similar, closely related organisms • Members of different groups usually cannot breed with one another.

  12. e.g. (genus Felis – small cats) House Cat, Bobcat, and Ocelot Ocelot Bobcat House Cat

  13. Genus Felis • On the opposite example page • Draw aHouse Cat, Bobcat and Ocelot • Label it • Genus Felis – (small cats) • Characteristics: • Sharp, retractable claws, purring and stalk their prey House Cat House Cat Bobcat Ocelot

  14. Genus Canis • On an example page • Draw aWolf, Coyote, and Husky • Label it • Genus Canis – domestic and wild dogs) • Characteristics: • You write 3 similar characteristics                              <> Wolf Wolf Husky Coyote

  15. Linnaeus’ naming system - • Species (Spaghetti)- • Second part of an organism’s scientific name • This name is not capitalized • Group of similar organisms that can mate and produce fertile offspring • Sets one species apart from another • Together a genus and species name – • Make up a scientific name • Identify one kind of organism

  16. Genus Ursus- bears • On an example page • Draw the 3 bears • Label each bear • AmericanBlackBear -Ursus americanus, • Brown (Grizzly) Bear - Ursus arctos • Polar Bear - Ursus maritimus AmericanBlackBear - Ursus americanus Brown (Grizzly) Bear - Ursus arctos Polar Bear – Ursus maritimus

  17. Remember • Genus – first part of scientific name • species – second part of scientific name • Genus name for American BlackBear - • Ursus • species name for American Black Bear - • americanus Ursus americanus

  18. Genus name for Brown (Grizzly)Bear - • Ursus • species name for Brown (Grizzly)Bear - arctos Ursus arctos

  19. Genus name for PolarBear - • Ursus • species name for PolarBear - maritimus Ursus maritimus

  20. Seven Levels of Classification - Kingdom Phylum Class Order Family Genus Species

  21. Kingdom -Broadest classification level 6 Kingdoms

  22. 6 Kingdoms Brain pop • http://www.brainpop.com/science/seeall/ • Newportps • Newport

  23. Kingdom -Broadest classification level • Phylum – subdivision of a Kingdom • Class – subdivision of a Phylum • Order – subdivision of a Class • Family – subdivision of an Order • Genus – subdivision of a Family • Species – subdivision of a Genus • Which classification level is broader than the Family level? • a. genus b. species c. queendom d. order

  24. Kingdom -Broadest classification level • Phylum – subdivision of a Kingdom • Class – subdivision of a Phylum • Order – subdivision of a Class • Family – subdivision of an Order • Genus – subdivision of a Family • Species – subdivision of a Genus • Which classification level is more specific than the Family level? • a. order b. class c. momdom d. genus

  25. More Review Questions • ___ is a group of organisms that can mate and produce fertile offspring. • A. Species B. Genus C. Kingdom

  26. More Review Questions The organism’s name for Chimpanzee is Pan troglodytes • What is the Species name? • a. Chimpanzee b. Pan c. troglodytes • What is the Genus name? • a. Chimpanzee b. Pan c. troglodytes

  27. Common Traits Exercise • Look at the Upside down wedding cake on page 187. • What are the common characteristics in each level? • Carefully look at theKingdom level - , make a list of common characteristics? • Single Cell or Multicellular ? • Autotrophs or Heterotrophs Animals ? • Multicellular, Heterotrophs Animals
