Classifying Animals Chapter 1 Lesson 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”
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
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
Invertebrates • No backbone • Largest group • Very diverse
Invertebrates • Cnidarians- • Radial symmetry • Simple digestive systems • Examples: jellyfish and coral
Invertebrates • Echinoderms- • Spiny-skin • Sucker like parts to catch prey • Examples: starfish, sea urchins, sea cucumbers
Invertebrates • Sponges- • Simple organisms • No true body symmetry • Filter bits of food from water that passes through them
Invertebrates • Mollusks- • Soft bodies • Most have shells • Examples oysters, snails, squid, octopus
Invertebrates • Worms- • Simple organ systems • Bilateral symmetry • Many are parasitic • Examples: flatworms, roundworms, earthworms
Invertebrates • Arthropods- • Largest group of invertebrates • Jointed body parts • Exoskeletons • Bilateral symmetry • Examples: lobsters, spiders, insects
Invertebrates Characteristics Types • Cnidarians- jellyfish • Echinoderms- starfish • Sponges • Arthropods- lobsters, spiders • Mollusks- snails, squids • worms • No backbone • Largest group • Very diverse
Vertebrates • Have a backbone • Two types • Cold blooded • Warm blooded
Vertebrates • Fish • Cold blooded • Use gills to obtain oxygen
Vertebrates • Amphibians • Cold blooded • Begin life in water but do not live life there • Need water to reproduce • Ex: frog, salamander, newt
Vertebrates • Reptiles • Cold-blooded • Most lay eggs • Dry, scaly skin • Examples: lizards, snakes, turtles
Vertebrates • Birds • Warm blooded • Lay eggs • Feathers (some fly, others don’t) • Examples: ostrich, penguin, robin
Vertebrates 5. Mammals • Warm blooded • Complex body systems • Large brain • Fur, live birth, feed milk to young • Example: bear, kangaroo, whale
Vertebrates Characteristics Types • Fish • Amphibians • Reptiles • Birds • Mammals • Has backbone • 2 types • Cold blooded • Warm blooded Cold blooded Warm blooded
Classification System • Used to identify and categorize organisms • Cut out ANIMAL CLASSIFICATION chart from page 20 of your workbook and paste in notes!
