chapter 4 vocabulary
Chapter 4 Vocabulary
  • adaptation: a structure or behavior that helps a living thing live in its surroundings.
  • adapted: made fit to live under certain conditions.
  • protective colorations: colors or patterns on an animal that help keep the animal from being seen by predators.
  • migration: movement from one place to another when the seasons change.
  • hibernate: to spend the winter in a state in which the body greatly slows down.
  • nitrogen: a material that plants need to grow.
  • annual: a plant that lives only one year.
  • evergreen: a plant that stays green all year, including firs, spruces, and pines.
  • perennial: a plant that can live two years or more.
what is an adaptation
What is an adaptation?
  • An adaptation is a change in an animal’s physical structure or behavior that helps an animal to survive in their habitat.
    • Examples: The shape of a bird’s beak, number of fingers and toes, or the color of an animal’s fur.
  • Physical adaptations do not develop during one lifetime, but over many generations.

Chapter 4 Lesson 1 How do Adaptations help Animals and Plants Survive p.88-91

example of adaptation
Example of Adaptation
  • The shape of an animal’s teeth is related to its diet.
    • Herbivores, such as deer, have many molars for chewing tough grass and plants.
    • Carnivores, such as lions, have sharp canines to kill and tear meat.
who experiences adaptations
Who experiences adaptations?
  • All species have experienced adaptation and will continue to slowly adapt as the next generations are born.
  • We will identify certain species from each of these groups and the reasons for their success:
    • Mammals
    • Birds
    • Reptiles
    • Amphibians
mammals
Mammals
  • Endothermic or

warm-blooded

  • All have some type of “hair”
    • Some are very specialized, such as white polar bear fur
  • Method of locomotion
  • Care for young
birds
Birds
  • Leg Length
    • Roseate Spoonbill (top right)
  • Foot Webbing
    • Laughing Gull (top left)
  • Beak Shape
    • Long Billed Curlew (bottom)
reptiles
Reptiles
  • Exothermic or cold- blooded
  • Scales
  • Some undergo hibernation
  • Lay eggs on land
  • Leg structure and position
amphibians
Amphibians
  • Exothermic
  • Lay eggs in water
  • Partially of fully webbed feet
  • Have lungs or can absorb oxygen through their skin
animal defense
Animal Defense
  • Some animals use these methods of defense to protect themselves:
    • Camouflage
      • Snake
    • Mimicry
      • Mexican Milk Snake
    • Bright colors
      • Skunk and Poison Arrow Frog
    • “Hair” projections
      • Hedgehog quills
      • Deer Antlers
adaptation applications lions
Adaptation Applications: Lions
  • Why are the eyes of a lion set in front of the head rather than on the sides?
  • Answer: Eyes in front of the head allow for depth perception and ability to judge distances when hunting.
adaptation applications lions12
Adaptation Applications: Lions
  • What is the purpose of the mane on a male lion?What is the reason for the lion’s color?
  • A thick mane helps the male to appear larger and serves as protection for the throat. The tawny brown coat color camouflages the animal and young among vegetation.
adaptation applications giraffe
Adaptation Applications: Giraffe
  • Why are giraffes able to go for long periods of time without water?
  • Answer: Giraffes drink water when available, but can go weeks without it. They rely on morning dew and the water content of their food.
adaptation applications giraffe14
Adaptation Applications: Giraffe
  • How are their long necks adapted to their lifestyle?
  • Answer: This extra length is thought to have evolved to help the giraffe spot predators and other giraffes in the distance. Interestingly, giraffes and humans have the same number of vertebrate in their necks.
adaptation applications zebras
Adaptation Applications: Zebras
  • How do zebras defend themselves?
  • Capable of running up to 40 mph. Zebras defend themselves by kicking and biting. Coloration also plays a role in evading predators, although theories have not reached an agreement.
adaptation games
Adaptation Games
  • Animal Adaptations Game
  • Harcourt animal adaptation game
what is hibernation
This is a very special kind of deep sleep

It is brought on by short day lengths, cold temperatures and food shortages

It is a survival strategy

Dropping into a deep hibernation means animals are using less energy

Food is scarce

Animals miss the cold seasons

Why do animals hibernate?

What is hibernation?

Chapter 4 Lesson 2 How Are Animals Adapted to Their Environment? p.92-97

how do animals prepare for hibernation
How do animals prepare for hibernation?
  • They try to put on as much fat as possible because they wont be eating much during the winter
  • This is called brown fat, which is found across the back and shoulders, close to an animal’s organs
  • Brown fat works hard to deliver quick energy to an animal coming out of hibernation

Can you think of any animals that hibernate?

Bear

Snake

Squirrels

Bats
