Classifying Animals Objective: SWBAT: Classify animals into major groups vertebrates or invertebrates and their subgroups according to their physical characteristics.

How are animals classified? Big Idea: Animals are classified into two major groups vertebrate and invertebrate and then further sorted into subgroups based on physical characteristics Essential Question: How are animals classified?

Content Based Vocabulary Words

organism - living things / plants or animals

animals - organisms that can be made of many parts and cannot make their own food

vertebrates - animals with backbones

invertebrates - animals without backbones

Notes From The Lesson Lesson Focus: Classifying Animals Essential Question: How are animals classified?

Animals Vertebrates Animals with backbones Invertebrates Animals without backbones Animals are classified into two major groups vertebrate and invertebrate based on their physical characteristics

Animals with backbones. Other physical characteristics Vertebrate Animals Animals with backbones. Other physical characteristics a protective skin covering an inside skeleton blood that circulates through blood vessels lungs or gills for breathing.

Vertebrates are divided into five groups Fish Amphibians Reptiles Birds Mammals Vertebrates are divided into five groups based on physical characteristics.

FISH * body temperature changes with its environment * breathes with gills * (most) have scales and fins * most lay eggs

AMPHIBIANS young lives in water and breathes with gills adults breath with lungs on land have smooth, moist skin most lay eggs body temperature changes with its environment

REPTILES * breath with lungs * have scales or plates * most lay eggs * its body temperature changes with its environment

* breathes with lungs BIRDS * have feathers, a beak, two wings, and two feet * lay eggs * constant body temperature

MAMMALS * nurse their young with milk * give birth to live offspring * constant body temperature * breathes with lungs * have fur or hair

Invertebrate Animals Animals without backbones. Some have outer covering or shell (insects, crabs, or clams) Others don’t have a hard covering or shell (jellyfish or worms) Examples of invertebrates: spiders, shrimp, crayfish, sponges, sea stars, or snails.

worms crabs insects spiders crayfish jellyfish shrimp sponges clams sea stars snails

Turn and Talk Turn and Talk to a buddy to discuss what you learned about classifying animals

Guided Practice Classifying Animals Interactive Game Vertebrate or Invertebrate

Group Work This is a silent thinking game Choose a card and hold it up in front of you Find a classmate that holds a animal card that is in the same classification group and subgroup as your animal Think about what characteristics your animal has that makes it a fit in your group Turn and Talk with your group to discuss your reasoning as to why the animals they are grouped together. A team representatives will share their group conclusions with the class.

Independent Practice Cut animal cards and order them according the clues given by the teacher guide sheet.

Content Writing From Lesson

Pretend you are a vertebrate animal. What animal would you be? Why? How are you different than an invertebrate animal? Describe your physical characteristics. What other category (fish, amphibian, reptile, bird, or mammal) would you be classified as?
