2 EQ: How are living things classified? Vocab: binomial nomenclature, genus, kingdom Initial Activity: What is the difference between potential and kinetic energy? Take out your homework to be collected Homework: Finish evaluation questions, memorize phylogeny

3  Charolus Linnaeus looked at organisms and grouped the individuals that had similar structure together  Structure is the way things are shaped or formed.  Linnaeus created a system called binomial nomenclature

4  Scientists study fossils, hereditary information, and early stages of development to determine classification  Two Words Genus: group of similar species Second word describes the feature that distinguishes the group.

7  Help avoid mistakes  Similar evolutionary histories are classified together  Give descriptive information about the species

8 Scientists use the phylogeny of an organism, how it developed from birth, heredity information and fossils to classify organisms

11 Essential Question: How can I classify different organisms? Initial Activity: Ms. Rizzo’s Closet  Ms. Rizzo loves to shop! When I get home from Macy’s or Nordstrom’s I always make sure to put my purchases away in the right place. I put all of my dresses on one side of my closet, all of my shirts on the other. I fold all of my pants and put them in drawers. In one drawer I put all of my jeans and in another I put all of my dress pants. I put all of my shoes on the bottom of my closet. On one side I put my heels on the other side I put my boots.  Draw a diagram of Ms. Rizzo’s closet. Label the diagram.

12 Characteristics I COULD use? Characteristics I COULD NOT use? -body shape -symmetry -Sex -Age Scientists use physical characteristics to classify organisms. Review: Why would I want to classify organisms?

13

14 Create your own classification system Split apart your items into two groups each time until you are left with a single item Create a web to display your system Organism Number Characteristic

16 EQ: How can I use a dichotomous key to classify a group of organisms? IA: Write three similarities and three differences between these pictures Dragonfly Grasshopper Ladybug Housefly

17 EQ: How can I use a dichotomous key to classify a group of organisms? IA: Answer questions 3-6 on the handout`

18  “Dichotomous” means “divided into two parts”. Therefore, dichotomous keys always give two choices in each step. They are useful because you can figure out what something is by just observing it  A Dichotomous key is like a scavenger hunt. You follow the directions to figure out what you know  Broad to specific  Only use positive terms

19 Dragonfly Grasshopper Ladybug Housefly

20  First create a web to split up the organisms into two groups until you reach one organism in each box  Create a dichotomous key of the mythical creatures.
