B. Cole EDUC 730: Lesson Plan
HAVE BACKBONES AND SKULL BONES
Vertebrates
B. Cole EDUC 730: Lesson Plan
Animals such as fish, amphibians, reptiles, birds, and mammals have backbones
B. Cole EDUC 730: Lesson Plan
Scientist classify
vertebrates into several main
groups:
Jawless Fish
Cartilage FishBony Fish
Amphibians
Reptiles BirdsMammal

B. Cole EDUC 730: Lesson Plan
Fish
Three groups: 1. jawless fish2. cartilage fish3. bony fish
A fish has:scaly skin, gills, heart with two chambers
Most fish have fins.All fish live in water and are cold-blooded animals.
cold-blooded: changes with the temperature of its environment
scales: thin, overlapping pieces of bonelike material that covers the bodies of most fish. Forms a protective covering.
B. Cole EDUC 730: Lesson Plan
Amphibians
Cold-blooded vertebratesHave a heart with three chambersLive part of their lives in water and part on
landLay eggs in water or in moist places
Examples: Frogs, toads, newts and salamanders Young frogs are called tadpoles The change into adult frogs through different stages is
metamorphosis. They eat large quantities of flies, mosquitoes and other
insects
B. Cole EDUC 730: Lesson Plan
Reptiles
Group of vertebrates that are more complex than amphibians
Cold-blooded vertebrateHas dry, scaly skinMost have two pairs of legs with five toes on
each legCan run, crawl, climb, or paddleBreath with well developed lungsMost reproduce by laying eggs on land
B. Cole EDUC 730: Lesson Plan
Reptiles continued…
4 Main groups: Turtles
Special shell covering for protection and movement Live on land, fresh water, ocean
Lizards Live in many places cold regions, rainy regions, dry deserts The skin color of many lizards changes with surrounding
conditions – camouflage
B. Cole EDUC 730: Lesson Plan
Reptiles continued…
Alligators and Crocodiles: largest kind of reptile Strong jaws and sharp teeth Live in warm, swampy areas along streams, rivers, or
lakes
Snakes Some live on land, some in water No legs Body covered with dry scales Move by catching their scales on the ground
and pushing forward with their muscles Do not tear or chew food, but swallow it whole
B. Cole EDUC 730: Lesson Plan
Birds
Warm-blooded animalHave hearts with 4 chambersHave wings, which are used for flyingFeathers are an important body covering
Protects body of the bird Aids in balancing and flying Also helps to control a bird’s body temperature
Many birds build nests in which they lay their hard-shelled eggs After the eggs hatch, the adult birds feed and protect
the young
B. Cole EDUC 730: Lesson Plan
Birds continued…
Birds live in different environments Penguins: cold, snowy areas Parrots: warm areas with much rain Ducks, geese, robins: change with season,
when the weather turns cold and snowy, many migrate to warmer areas.
Birds are an important food source for people
B. Cole EDUC 730: Lesson Plan
Mammals
Most complex group of animalsExamples: bats, moles, bears,
horses, rats, cows, monkeys, kangaroos, rabbits, seals whales and humans
A mammal is a vertebrate with a body covering of fur or hair, and special female organs that produce milk to feed its young.
They care fore their young until they are able to care for themselves
Live in nearly all kinds of habitats
B. Cole EDUC 730: Lesson Plan
Mammals continued…
Mammals have more complex brains than other animals
Humans are able to become skilled in the use of tools
Other mammals produce eggs that develop in different ways
A marsupial is a mammal that has a special pouch for carrying the undeveloped young
B. Cole EDUC 730: Lesson Plan
