  1. Classifying Animals Chapter 1 Lesson 2

  2. Table of Contents • Science Process Skills------------------1 • Parts of a Cell------------------------------ • Classifying Animals----------------------# • Use your Classifying Animals lab as the starting page for this lesson! • Turn to the next clean page (it can be the back of a page) and title it “CLASSIFYING ANIMALS”

  3. Vocabulary • Cut out all vocabulary terms on page 8 and paste them into your journal underneath the heading “classifying animals” • Cut out pictures and definitions of radial and bilateral symmetry on page 8 and paste below vocabulary definitions

  4. Characteristics of Animals • Multi-cellular • Require oxygen • Consume other organisms for food • Able to move at some point • Reproduce • Divided into 2 categories • Invertebrates • vertebrates

  5. Invertebrates • No backbone • Largest group • Very diverse

  6. Invertebrates • Cnidarians- • Radial symmetry • Simple digestive systems • Examples: jellyfish and coral

  7. Invertebrates • Echinoderms- • Spiny-skin • Sucker like parts to catch prey • Examples: starfish, sea urchins, sea cucumbers

  8. Invertebrates • Sponges- • Simple organisms • No true body symmetry • Filter bits of food from water that passes through them

  9. Invertebrates • Mollusks- • Soft bodies • Most have shells • Examples oysters, snails, squid, octopus

  10. Invertebrates • Worms- • Simple organ systems • Bilateral symmetry • Many are parasitic • Examples: flatworms, roundworms, earthworms

  11. Invertebrates • Arthropods- • Largest group of invertebrates • Jointed body parts • Exoskeletons • Bilateral symmetry • Examples: lobsters, spiders, insects

  12. Invertebrates Characteristics Types • Cnidarians- jellyfish • Echinoderms- starfish • Sponges • Arthropods- lobsters, spiders • Mollusks- snails, squids • worms • No backbone • Largest group • Very diverse

  13. Vertebrates • Have a backbone • Two types • Cold blooded • Warm blooded

  14. Vertebrates • Fish • Cold blooded • Use gills to obtain oxygen

  15. Vertebrates • Amphibians • Cold blooded • Begin life in water but do not live life there • Need water to reproduce • Ex: frog, salamander, newt

  16. Vertebrates • Reptiles • Cold-blooded • Most lay eggs • Dry, scaly skin • Examples: lizards, snakes, turtles

  17. Vertebrates • Birds • Warm blooded • Lay eggs • Feathers (some fly, others don’t) • Examples: ostrich, penguin, robin

  18. Vertebrates 5. Mammals • Warm blooded • Complex body systems • Large brain • Fur, live birth, feed milk to young • Example: bear, kangaroo, whale

  19. Vertebrates Characteristics Types • Fish • Amphibians • Reptiles • Birds • Mammals • Has backbone • 2 types • Cold blooded • Warm blooded Cold blooded Warm blooded

  20. Classification System • Used to identify and categorize organisms • Cut out ANIMAL CLASSIFICATION chart from page 20 of your workbook and paste in notes!

  21. Homework! • How Are Animals Classified? • Worksheet
