  1. Classifying Organism Key Question: How are living things classified? CHAPTER 1

  2. Chapter 1 Vocabulary Terms Definitions To place organisms into a group The highest level of the classification system The second highest level of the classification system The next level of classification below phylum The lowest level of classification Animals with backbones An animal without a backbone • Classify • Kingdom • Phylum • Class • Species • Vertebrate • Invertebrate

  3. Greek Philosopher Aristotle: Created one of the longest methods of classification: • Vertebrates VS Invertebrates • This means he divided animals by those with red blood cells separately than those with no red blood cells. • Backbone VS No Backbone • This was over simplified; so, over time the classifications system has grown.

  4. Compare & Contrast Writers use words: both, like, also, or as Scientists ask: “How are these events alike? How are they different?

  6. Lesson 1: Why do we classify? • Lewis & Clark: Atlantic to Pacific • Collected samples & observed and compared different organisms • Biologists used these observations to CLASSIFY these organisms • Classification makes it easier for scientists to communicate • Classification helps organize information about organisms: ex. (Plants need light)

  7. CLASSIFICATION SYSTEMS

  8. Dichotomous Key:A tool used to help classify and group There are many different kinds. PG.4

  9. Classifying Organism Key Question: How do we classify vertebrates? Lesson 2

  10. Animals are Unique! How? Chordata is the only PHYLUM of animals that contain spinal cords (VERTEBRATES). 1. Multicellular 2. Animals cannot make their own food 2. Can move on their own

  11. Mammals: All breathe air with lungs Make milk for their young Warm-blooded Body temperature is regulated Hair or fur

  12. Birth Growth Reproduce Death

  13. Similar Life Cycles – BUT… baby birds need to be fed… Reptiles are born ready to find their own

  14. Class of Vertebrates: Reptiles Birds • Cold Blooded • Scaly Skin • Young Feed Themselves • Non Mammal • Can lay eggs • Vertebrates • Feathers • Young are Fed • Warm Blooded • Lays Eggs • Vertebrates

  15. Characteristics of Amphibians: 1. Similar to reptiles2. Cold Blooded3. Soft, Moist Skin4. Hatch from eggs 5. Skin can absorb water and Oxygen6. Change more than any other vertebrate 7. Eventually develops lungs to breathe and no longer uses gills8. Changes more than any other amphibian9. METAMORPHIS

  16. 5 Stages

  17. Fish are the only water living class of vertebrates.

  18. Scientists study fossils to classify animals that lived in the past, and most dinosaurs where smaller in size.

  19. Dinosaur & Lizard Similarities 1. Backbones2. Scales3. Cold Blooded4. Many walked on 4 legs BUT… Legs are different … Dinosaur legs go straight up and down, while lizards’ are out to the side Dinosaurs also share features with birds. Example: feathers, wishbones, and the heart
