2Introduction Audience Objective This projects is intended for third grade students .Science Unit: Animal ClassificationVocabulary: Mammal, Fish, Bird, Reptile, AmphibianThis project will serve to review what the students know about animal classification as well as test that knowledge.ObjectiveThe student will review the qualities which scientist use to classify animals and practice using what they know to classify some animals on their own.S.IP Make purposeful observations of plants and animals using the appropriate senses.S.RS Demonstrate understanding of plant and animal structures and functions through illustrations, descriptions, or discussions.
3VertebratesAnimals with an internal skeleton made of bone are called vertebrates. There are about 58,000 species of vertebrates (that we know of). This is only a small percentage of all animals, but because of their mobility and size vertebrates usually dominate their environments.
4Scientists have classified vertebrates into five classes Scientists have classified vertebrates into five classes. These classes are mammals, birds, fish, reptiles and amphibians.
10They are all fish. Fish… are cold-blooded are aquatic (live entire life under water)lay eggsspend their entire lives in water.Most fish have gills and scales. Their limbs are modified into fins for swimming.
11Skill check! Which of these animal classifications is cold-blooded? mammalnonobirdfishYes!
15They are all amphibians. Are cold bloodedBegin life in water and end up on land
16Let’s see what you remember about the classification of vertebrates Let’s see what you remember about the classification of vertebrates! take the quiz
17This is a Golden Poison Frog. Although the golden poison dart frog is only the size of a paperclip, it is considered to be one of the most toxic animals on earth. The golden poison dart frog is cold blooded. It is born from an egg under water, but spends its adult life on land.What is it?MammalBirdFishReptileAmphibian

19Sorry, the golden poison dart frog is born in the water and spends its adult life on land. Try again Review
23Sorry, the emu is warm- blooded. Try again Review
24Great job. Although the emu is flightless, it is still a bird Great job! Although the emu is flightless, it is still a bird! How about another one?
25This is a sharkSharks have rows of teeth that are embedded in their gums instead of their jaw. Sharks are aquatic so they have gills and fins. They are cold-blooded.What is it?MammalBirdFishReptileAmphibian
26Sorry, but sharks do not have fur. Try again Review
27Sorry, the shark is aquatic and spends its entire life under water Sorry, the shark is aquatic and spends its entire life under water. Try again Review
33This is a dolphin.Dolphins are warm-blooded. They are aquatic, but breath air. They are not born from eggs.What is it?MammalBirdFishReptileAmphibian
34Sorry, dolphins are warm-blooded. Try again Review
35Sorry, dolphins are not born from eggs. Try again Review
36Great job! Even though dolphins live under water and their fur is not visible they are mammals! How about another one?
37This is a platypus.A platypus has fur and is warm-blooded. It has webbed feet which help it swim. It’s bill-like snout is actually covered with soft moist skin. They platypus lays two eggs once a year.What is it?MammalBirdFishReptileAmphibian
38The platypus is a mammal, despite the fact that it lays eggs The platypus is a mammal, despite the fact that it lays eggs. It belongs to a sub-group of mammals called monotremes which lay eggs. Only two animals belong in this group, the platypus and the echidna. To learn more about monotrens visit this website: Even in science there are exceptions to the rules!
