Transcript of How Animals Live?

  • How Animals Live?How do different animals live, grow, and change?

  • All animals need water, oxygen, food, and shelter Animals can be classified, or divided, into two groups. Those that have a backbone. Those that dont have a backbone. A backbone is a series of bones that run down the back of some animals. An animal that has a backbone is called a vertebrate

    Classifying VertebratesA body feature passed on toan animal from its parents is calleda trait. Traits can include things an animal does.

  • A Vertebrate such as this horse has a skeleton inside its body.What is the series of bones that runs down my back called?A. Root stemB. backboneC. Vertebrate

  • Vertebrates can be classified into several smaller groups. One of these groups is the mammal group. A mammal is an animal that has hair/fur and produces milk for its young. They need oxygen, a gas in the air, to live and they breath the air with their lungs. Most mammals have a thick coat of hair or fur that Traps air against their body for warmth. Mammals

  • Sea lions are mammals that live both in water and on land. Even Mammals that live in water have lungs and most breath air.What are two traits ofMammals?

  • A bird is a vertebrate that has feathers, wings, and two legs. Birds lay eggs that have hard shells.Most birds can fly.Feathers keep a bird warm, but are light so they do not weigh the bird down.Birds

  • Bird of Paradise are found in western Indonesia, Papua New Guinea, and eastern Australia. The members of this family are perhaps best known for the plumage of the males of most species. How are the bodiesof mammals and birds alike and different?

  • Fish are vertebrates that live in water. Fish have long, narrow bodies that make it easy to move through water. Fish are vertebrates that live in water. Most fish are covered with scales that protect them. Like all animals fish need oxygen to live, but they dont have lungs. Instead they breath through gills.Fish

  • All fish have backbones. Sharks and Rays have backbonesMade of cartilage, a material that is softer than bone.What are two traits of fish?

  • An amphibian is a vertebrate that starts life in water and then lives on land as an adult. Amphibians lay eggs in water and their young breath through gills and have tails to help them swim. As the young grow, their bodies change. Lungs and legs grow and gills disappear. After an amphibians body changes, they live on land.Amphibians

  • Frogs have wet, smooth skin. Wet skin prevents their bodies from drying out on land.

    An animal lives in water, has fur, and breatheswith lungs. Would you classify it as a bird,a mammal, a fish, or an amphibian?

  • A reptile has dry, scaly, skin and lays eggs on land. The scales protect them from the hot sun Reptiles can live in many different environments. Some use legs to move, others slither on the ground. All reptiles breath with lungs and reptiles that spend a lot of time in water must stick their noses out to breath.


  • Why do alligators and crocodiles have to stick their noses outof the water?

  • Directions: If you think the animal is a mammal, circle it. If its a fish, put an X through it. If you think its a bird, box it. If you think it is a reptile, triangle it.Animal Classification Game

  • Animals without a backbone includes sea stars, butterflies, and spiders Many invertebrates are very small a soft sac filled with liquid supports worms and sea jellies Insects and other arthropods have a hard covering on theoutside of their bodies.Invertebrates

  • Major Kinds of Invertebrate Animals

  • Directions: If you think the animal is a sea jelly, circle it. If its a worm, put an X through it. If you think its a Mollusk, box it. If you think it is a arthropod, triangle it.

  • Chapter two lesson one and twoQuiz log in to Mr. Elliotts website and go to 3rd grade science interactive. At the very bottom under files you will find Ch. 2-1 quiz. Open it and finish the quiz. Print off when finished.
