Audience This projects is intended for third grade students. Science Unit: Animal Classification Vocabulary: Mammal, Fish, Bird, Reptile, Amphibian This project will serve to review what the students know about animal classification as well as test that knowledge. Objective The 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.
Animals 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.
Scientists have classified vertebrates into five classes. These classes are mammals, birds, fish, reptiles and amphibians.
Mammals… have fur. are warm blooded. have live birth. produce milk to feed their young.
Birds… have feathers. are warm blooded. lay eggs.
Fish… are cold-blooded are aquatic (live entire life under water) lay eggs spend their entire lives in water. Most fish have gills and scales. Their limbs are modified into fins for swimming.
Which of these animal classifications is cold-blooded? mammal bird fish no Yes!
Reptiles… are cold blooded usually have scales lay eggs
Amphibians… Are cold blooded Begin life in water and end up on land
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? Mammal Bird Fish Reptile Amphibian
An emu can be over 6 feet tall. It has feathers, but cannot fly. It is warm- blooded and lays eggs. WHAT IS IT? Mammal Bird Fish Reptile Amphibian
Sharks 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? Mammal Bird Fish Reptile Amphibian
Crocodiles spend a lot of time in the water, but they breath air. They are cold- blooded animals. They lay nests of eggs called clutches. What is it? Mammal Bird Fish Reptile Amphibian
Dolphins are warm- blooded. They are aquatic, but breath air. They are not born from eggs. What is it? Mammal Bird Fish Reptile Amphibian
A platypus has fur and is warm-blooded. It has webbed feet which help it swim. Its bill-like snout is actually covered with soft moist skin. They platypus lays two eggs once a year. WHAT IS IT? Mammal Bird Fish Reptile Amphibian
You sure know a lot about animals.
Mammals Are warm blooded Have live birth Have fur Drink mothers milk Birds Are warm blooded Lay eggs Have feathers Fish Are cold-blooded Lay eggs Have gills, scales, and fins Reptiles Are cold-blooded Live on land Lay eggs Amphibians Are cold-blooded Begin life in water then live on land ReviewBack
