CHARACTERISTICS: � 1. made of cells � 2. They reproduce � 3. They move � 4. They eat food � 5. They grow and change CHARACTERISTICS OF ANIMALS

VERTEBRATES INVERTEBRATES � All animals that have backbones. � Fish, amphibians, retiles, birds, and mammals animals that do not have a backbone. � Arthropods- (insects, crabs, spiders) � � Text p. 22 -23 Answer checkpoint question 1 on p. 23 VERTEBRATES VS. INVERTEBRATES

WARM BLOODED COLD BLOODED � The body of a Warm Blooded animal does not change much. body of a Cold Blooded animal changes depending on their surroundings. WARM BLOODED VS. COLD BLOODED

Animals are classified into different types of groups. : To study the many forms of animal life in a systematic way, scientists have divided the animal kingdom into groups. These groups are largely based upon the structure of the animal's body. Information is from: http: //kids. britannica. com/comptons /article-196401/animal ANIMAL CLASSIFICATIONS � Insects � Amphibians � Mammals � Reptiles � Fish � Birds Open up to textbook p. 18

� Fish are usually covered in scales. They live only in water. Fish breathe mostly by using their gills. Fish are cold blooded and most lay eggs. � There fish: 1. 2. FISH 3. are three classes of the primitive jawless fishes, or Agnatha the cartilaginous (shark like) fishes, or Chondrichthyes the bony fishes, or Osteicht http: //answers. encyclopedia. com/question/three-classes-fish 86809. htmlhyes.

� Amphibians are covered with a smooth skin � They can live on both land in the water. � They breathe by using their gills or with lungs, sometimes even both! � They are cold blooded � They hatch from eggs AMPHIBIANS

� Reptiles are covered in scales � Most reptiles live on land � Some can live in water � They use their lungs to breathe � They are cold blooded � They usually lay eggs REPTILES

� Birds are covered with feathers. � They usually live on land, but some spend a great deal of time on water � Birds breathe using lungs � They are warm blooded � They lay eggs BIRDS

� All mammals have hair or fur � Most live on land, but a few live in water � They use lungs to breathe � Mammals are warm blooded, they control their body temperature � Most mammals have live births MAMMALS

APPLY TO LEARNING � Draw this chart in your copybook and list whether each classification is cold blooded or warm blooded: FISH, AMPHIBIANS, REPTILES, BIRDS, MAMMALS COLD BLOODED WARM BLOODED

CREATE A GRAPH � Create a graph that compares the size of animals to the number of young they bear. Size Small. Medium. Large- Animal Number of Young

LIFE CYCLES OF ANIMALS Animals have a variety of life cycles. Each life cycle depends on the species and can vary greatly. Let’s read pages 20 and 21 together!
