1. Classifying Living Things
5th Grade Science

2. 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

3. 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

4. 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

5. Smaller Groups Kingdom Phylum Class Order Family Genus Species
Genus and species
Scientific name:
Ursa arctos= brown bear
Homo sapien= human

6. Animals with a backbone
Vertebrates are animals that have a backbone

7. 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

8. 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

9. Vertebrates continued
5) Birds: have feathers, lay eggs, and most can fly. Robins, chickens, parrots.

10. 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?

11. 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

12. Animals without a backbone
Invertebrates: are animals without a backbone.
Insects
Spiders
Shrimp
Clams
Oysters
starfish

13. 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?

14. 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

15. 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
