  1. Classification

  2. The History of Organization Aristotle 384-322 BC Interested in biological classification. Patterns in nature. Carl Linnaeus 1707-1778 ACE Father ofBiological Classification!

  3. Binomial Nomenclature Two-word naming system • Genus • Noun, Capitalized, Underlined or Italicized • Species • Descriptive, Lower Case, Underlined or Italicized

  4. Common name: Robin • Erithacus rubicula • Turdus migratorus

  5. Common name: Black and Polar Bear Ursus americanus Ursus maritimus

  6. The Science of Classification Scientist who classify or organize organisms (animals and plants) are called taxonomists. Taxonomists study taxonomy.

  7. What is Classification? Classification arranges objects, ideas, or information into groups by finding common traits or characteristics.

  8. In order to make their job easier, scientists classify living things into groups, based on how they are the same, and how they are different.

  9. Engage Activity: Classification • With your table, take a baggy and classify the items into 2 groups. • Write down the characteristics for each group. • Split those groups into 2 groups. • Write down the common characteristics for those new groups. • Continue until you have classified the entire bag. Are your groups: the same, similar or different?

  10. Cladograms are used to… • Organize organisms based on evolutionary relationships. In other words… • who is related to who and where did we come from…

  11. Quick Lab – Creating Cladograms • Turn to page 453, in your text book • You and a partner have 10 minutes to complete this activity. • Turn in for a grade

  12. Groups are also arranged in hierarchicalorder.

  13. Hierarchical Classification • Taxonomic categories • Kingdom (big) King • Phylum Philip • Class Came • Order Over • Family For • Genus Grape • Species (small) Soda

  14. Engage Activity - Mnemonic On a sheet of paper, create your own sentence to help you remember the order of classification. King Philip Come Over For Grape Soda

  15. What are Dichotomous Keys? • a method for determining the identity of something (like the name of a butterfly, a plant, a lichen, or a rock) by going through a series of choices that leads the user to the correct name of the item. • Dichotomous means "divided in two parts".

  16. Using a dichotomous key At each step of the process of using the key, the user is given two choices; each alternative leads to another question until the item is identified. 1a. If the leaves are flat….go to question 4. 1b. If the leaves are needle-like….go to question 2. 2a. Are the needles in a bunch? Go to question 5 2b. Are they spread along the branch?“…pine tree Eventually, when enough questions have been answered, the identity of the tree is revealed.

  17. Engage Activity –Using a Dichotomous Key Using the dichotomous key at the back table, complete the worksheet “Using a dichotomous key” When done, come to the front and be ready to check your answers.

  18. Answers – Alien Dichotomous Key • Duffnut 9. Uniped • Swampstomper 10. Schmooman • Duoplus 11. Roadrunner • Aurilobber 12. Chickaworm • Guzzlelot 13. El Strato • Gorkel 14. Serpentog • Snorkelese 15. Babluch • drewella

  19. Why is Taxonomy Important? New Discoveries Unknown species discovered. Questions New fossil Uncovered. How can you answer these questions?

  20. Exit Ticket On a half sheet of paper and in your own words, what did I want you to learn during this power point (give at least 2 things)? Don’t list the activities…tell me what was the point.
