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.

VERTEBRATE CLASSIFICATION Write these questions and try to answer them to the best of your ability in your science journal! 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?

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

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

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

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 Amphibians Birds Reptiles Reptiles Mammals

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

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

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.

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.

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 Mammals 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

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

Please write in your science journal! What are the characteristics of all vertebrates (fish, amphibians, reptiles, birds, and mammals)? ____________________________ MORE REVIEW !

A Review of Vertebrates Write the answers in your science journal! What kingdom do all vertebrates belong? _____________________ What phylum? _____________________ What subphylum? _____________________ THE LAST REVIEW PAGE!

PLEASE WRITE THE ANSWERS IN JOURNALS! 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?
