Classifying Living Things 5th Grade Science
Classification The act of grouping things by using a set of rules is called classification. Why classify? To organize living things so they can be studied and discussed
5 Kingdoms A Kingdom is the largest group into which living things can be classified. 1) Animals: get their food from other things 2) Plants: make their own food
5 Kingdoms Con’t. 3) Fungi: plant like, but can’t make their own food. Mushrooms 4) Protists: one celled organism with a nucleus 5) Monerans: one celled organism without a nucleus
Smaller Groups Kingdom Phylum Class Order Family Genus Species Genus and species Scientific name: Ursa arctos= brown bear Homo sapien= human
Animals with a backbone Vertebrates are animals that have a backbone
5 Groups of Vertebrates 1) Mammals: have hair and produce milk for their young. Cats and dogs 2) Reptiles: have scales, dry skin and lay eggs. Lizards, turtles, snakes
Vertebrates continued 3) Amphibians: have moist skin and no scale. They begin life in water and live on land. Frogs and salamanders. 4) Fish: live entire life in water and have gills, and have scales
Vertebrates continued 5) Birds: have feathers, lay eggs, and most can fly. Robins, chickens, parrots.
Skeleton: The structure that protects and supports an organism Endoskeleton: a skeleton made of bone and cartilage that you and other vertebrate animals have. Exoskeleton: a hard outer covering that invertebrates have insects and shrimp for example. What kind of skeleton is this?
Body heat regulation Cold-blooded: the organisms’ body temperature is regulated by the outside temperature. Amphibians, fish, and reptiles Warm-blooded: the organisms’ body temperature is regulated by the body to maintain or keep a constant temperature. Mammals and birds
Animals without a backbone Invertebrates: are animals without a backbone. Insects Spiders Shrimp Clams Oysters starfish
Predator: an animal that hunts others Prey: an animal hunted or caught for food Carnivore: meat eater Herbivore: plant eater Omnivore: eats both plants and meat Which one is what type of eater?
Plants Vascular plants: have tubes that can be found in roots, stems, and leaves. The tubes carry water and nutrients throughout the plant. Example: trees, bushes, flowers
Plants continued Nonvascular plants: don’t have tubes to carry water and nutrients throughout the plant. Water and nutrients have to pass from cell to cell. Have to live in shady damp places. Example: moss
