  1. Scientific Classification Classification, taxonomy, taxonomic key Kingdom, phylum, class, order, family, genus, species

  2. Observable Properties • What is an observable property? • Why is it important in scientific classification?

  3. Classification • Define living: • Define non-living: • Define once-living:

  4. Examples • Give 3 examples of living things: • Give 3 examples of non-living things: • Give 3 examples of once-living things:

  5. Scientific Classification • What things are classified scientifically? • What are structural characteristics?

  6. Scientific Tool • Classification is a scientific tool • It describes perceived patterns in nature.

  7. Kingdoms • What are the kingdoms of living things? • List their characteristics 1- 2- 3- 4- 5- 6-

  8. Levels of Classification Do………………. • Kings……………. • Play……………… • Chess……………. • On……………….. • Fine……………… • Green…………… • Silk?……………….

  9. Binomial Nomenclature • Every organism that is classified has a scientific name. • This name has two parts • The first name is the name of the genus and is capitalized. • The second name is the name of the species and is written in lower case. AcinonyxJubatus Aconitum columbianumArtiodactylasuidae

  10. Taxonomic Keys • A taxonomic key is paired statements that give characteristics of an organism. • You choose which statement applies to the organism you are trying to classify. • You continue through the key by stating the characteristics. • Once you have completed the steps, you arrive at the scientific name of the organism.

  11. Taxonomic Key Example • A taxonomic key is a tools used to identify and classify organisms. Most keys consist of a set • of paired statements describing a certain trait. By choosing from a series of these paired traits, a • biologist can place an unknown organism in smaller and smaller groups until the organism is • either identified or proved to be something new. • Use the following key to identify the leaves on the next page. Write the steps used and the • scientific and common name of each tree in the spaces provided. (use the leaf terms at the • bottom of the leaf page to help) • 1a. Leaves needlelike: Go to 2 • 1b. Leaves broad with flattened surface or blade: Go to 6 • 2a. Needles up to 2.5 cm long: yew, Taxuscanadenis • 2b. Needles 5.0 cm or longer: Go to 3 • 3a. Needles 5.0 to 12.5 cm long: Go to 4 • 3b. Needles more than 12.5 cm long: Go to 5 • 4a. Needles in cluster of two: Scotch pine, Pinussylvestris • 4b. Needles in clusters of four or five: white pine, Pinusstrobus • 5a. Needles in clusters of two: black pine, Pinusnigra • 5b. Needles in clusters of three: ponderosa pine, Pinus ponderosa • 6a. Leaves divided into separate leaflets or little leaves: Go to 7 • 6b. Leaves all in one piece; no leaflets: Go to 8 • 7a. Leaves with five to seven leaflets, bottom pair smallest: shagbark hickory, Caryaovata • 7b. Leaves with thirteen to forty one leaflets: tree of heaven, Ailantbusaltissima • 8a. Leaf edge smooth, no saw-teeth: flowering dogwood, Cornusflorida • 8b. Leaves saw-toothed or lobed: Go to 9 • 9a. Leaves saw-toothed, veins like barbs on a feather: beech, Fagusgrandifolia

  12. Taxonomic Key Practice • Look at the salamander pictures on your table. • Study the dichotomous key to find the name of your salamander • Have everyone on your table find the name of a different salamander • Include a description and a name of your salamander.
