1 Teacher PageThe 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.
5 VERTEBRATE CLASSIFICATION Write 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 ANIMALIAPHYLUM CHORDATASUBPHYLUM VERTEBRATATALKING IGUANA
8 that Vertebrates share. They are: As a green iguana, let metell you all thecharacteristicsthat Vertebrates share.They are:backbonebilateral symmetrycoelomate animals that have endoskeletonclosed circulatory systemefficient respiratory systemcomplex brain and nervous system5 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!FishAmphibiansBirdsReptilesMammals
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 heartHave 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 ReptilesExamples-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 lungsscaly 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 heartHave mammary glandsHave lungsHave hair for insulation3 Types of Mammals3 Types of Mammals
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 ofvertebrates!ARE YOU READY?BEGIN REVIEW
17 Please write in your lab notebook 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 Vertebrates Write 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?
