Presentation Transcript

  1. Teacher Page • The learner will be able to classify living things into groups based on structure. • The learner will be able to understand that organisms are classified according to their structural similarities which mirror their evolutionary relationships. • The teacher can use this production to show similarities and differences in vertebrates. • The students should use science journals to write in answers as the teacher proceeds through the program. • The teacher should use this as an introduction to vertebrates and seize the opportunities to have class participation by leading a guided discussion.

  2. CLASSIFICATION OF VERTEBRATES Teacher Page Activity

  3. Pre AP Biology May 3 and 4 • Kingdom Animalia: Phylum Chordata: Subphylum vertabrata • Seastar dissection continued Homework: • SG no change • Optional Flower Dissection due May 7 and 8 • Benchmark coming up

  4. CLASSIFICATION OF VERTEBRATES Activity

  5. VERTEBRATE CLASSIFICATIONWrite these questions and try to answer them to the best of your ability in your lab notebook! • 1. What is the kingdom in which all vertebrates are classified? • 2. What is the phylum in which all vertebrates are classified? • 3. What is the subphylum in which all vertebrates are classified?

  6. Why am I a vertebrate, and how am I like fish, amphibians, birds, and mammals? BEARDED DRAGON

  7. ALL VERTEBRATES BELONG TO THESE CATEGORIES: • KINGDOM ANIMALIA • PHYLUM CHORDATA • SUBPHYLUM VERTEBRATA TALKING IGUANA

  8. As a green iguana, let me tell you all the characteristics that Vertebrates share. They are: • backbone • bilateral symmetry • coelomate animals that have endoskeleton • closed circulatory system • efficient respiratory system • complex brain and nervous system 5 Major Groups

  9. FIVE MAJOR GROUPS OF VERTEBRATAES Create a chart with Fish, Amphibians, Birds, Reptiles, and Mammals at the top in your science journal. Under each heading write their characteristics!Click on each underlined group to learn more! Fish Amphibians Birds Reptiles Mammals

  10. Fish • 3 Types 1.Jawless (ex.-Lamprey, hagfish) 2.Cartlaginous Fishes(ex.-shark) 3.Bony Fishes(ex.-tuna, jack) • Ectotherms- body temperature is dependent on the surroundings. • 2 chambered heart • Have gills

  11. Amphibians“DOUBLE-LIFE” • Examples- Frogs, Toads, Salamanders. • As adults, they live on land, but rely on water for breeding and egg development. • All go through metamorphosis, in which the young gradually lose their tails and gills and develop legs, lungs, and other adult structures. • Ectotherms- body temperature is dependent on the surroundings. • 3 chambered heart

  12. Reptiles • Examples-snakes, lizards, turtles, crocodiles, and alligators. • Ectotherms- body temperature is dependent on the surroundings. • Most have 3 chambered heart, but crocodiles have a 4 chambered heart. • Have lungs • scaly skin reduces loss of body moisture on land. • Have amniotic egg- embryo in amniotic fluid.

  13. Birds • Have feathers. • Forelimbs modified into wings. • Have amniotic egg- embryo in amniotic fluid. • Incubate eggs in nests. • Endotherms-animals that maintain a constant body temperature. • Have thin hollow bones enabling flight. • Have lungs.

  14. Mammals • Examples- Humans, Dogs, Cats, Kangaroo ect. • Endotherms-animals that maintain a constant body temperature. • 4 chambered heart • Have mammary glands • Have lungs • Have hair for insulation • 3 Types of Mammals 3 Types ofMammals

  15. 3 Types of Mammals • Monotremes- lay eggs (example-platypus) • Marsupials- young develop in pouch of mother.(example-kangaroo, koala) • Placental-carry young inside the uterus until development is nearly complete. (example-humans, dogs, cats) REVIEW

  16. As an amphibian, an Argentine Horned Frog, let’s review the characteristics of vertebrates! ARE YOU READY? BEGIN REVIEW

  17. Please write in your lab notebook! What are the characteristics of all vertebrates (fish, amphibians, reptiles, birds, and mammals)? • ____________________________ • ____________________________ • ____________________________ • ____________________________ • ____________________________ • ____________________________ MORE REVIEW !

  18. A Review of VertebratesWrite the answers in your lab notebook! • What kingdom do all vertebrates belong? • _____________________ • What phylum? • _____________________ • What subphylum? • _____________________ THE LAST REVIEW PAGE!

  19. PLEASE WRITE THE ANSWERS IN your lab notebook! • What is a characteristic that birds and mammals share? • What are three major differences between birds and reptiles? • How would you compare and contrast fish, the most primitive vertebrate, and mammals, the most complex vertebrate?
