Title: Animal Growth and Adaptations

Animal Growth and Adaptations
  • Science
  • Unit A CH 1
  • 4th Grade

Where animals meet their needs
  • Environment everything that surrounds and
    affects the animal, including living and
    nonliving things

5 basic needs of animals
A climate zone map of the Earth-tropical, dry,
temperate, cold, and polar
  • Climate
  • Oxygen
  • Food
  • Water
  • Shelter

Fish use gills to get oxygen from water
All animals need water
Plants and animals are part of the food chain
Humans and mammals use lungs to get oxygen from
the air
Shelter is where an animals has its house
Basic needs of animals
  • Climate deserts are dry while rainforests are
  • Oxygen fish use gills while mammals use lungs
  • Food needed for energy to live and grow
  • Water from ponds, lakes, streams, puddles, food,
  • Shelter for protection from other animals and
    the weather

Animals and their young
  • Animals reproduce to continue their species.
    Animals grow and develop in many ways
  • Metamorphosis the process of the butterfly from
    egg to caterpillar to chrysalis to butterfly

Animal Adaptations
  • Adaptations are body parts or behaviors that help
    an animal meet its needs in its environment
  • 4 basic areas of adaptation are bird beaks, body
    coverings, camouflage, and mimicry

Bird Beaks
  • Thick, heavy beaks for seed-eaters
  • Short, stubby beaks for fruit eaters
  • Sharp, pointed beaks for insect eaters

Sandpipers eat insects
Finches eat fruit and berries
Toucans eat fruit and frogs
Red-tailed hawks eat mice and rodents
Pelicans use their beaks to scoop up fish
Other bird adaptations
  • Owls eyes
  • Hawks talons help with catching and carrying prey
  • Feathers keep a bird warm and dry
  • Hollow bones help with flying
  • Aerodynamic shapes help with swimming and flying

Body Coverings
  • Feathers protect birds and help them fly
  • Fur or hair keeps mammals warm
  • Sharp hair offer protection
  • Whiskers are sense organs
  • Scales protect fish from disease and predators,
    and help snakes to move

Color and Shape
  • Camouflage an animals color or pattern that
    helps it blend in with its surroundings so the
    animal can hide
  • Mimicry an animal looks like another animal or
    object to hide from predators

Viceroy butterfly
Stick bug
Tiger stripes
Behavior Adaptations
  • 3 basic types of behavior adaptations instinct,
    migration, and hibernation
  • Instinct behaviors that an animal is born with
    to help it meet its needs
  • Migration movement of a group of animals or
    people from one place to another and back again
  • Hibernation a period when an animal goes into a
    long, deep, sleep, usually during winter.

Geese migrating to a warmer area
Bear hibernating in a den
Whales migrating to warmer waters
Learned behaviors
  • Not all animal behaviors are instinct-some are
  • Cheetahs learn to hunt from their mothers
  • Chimpanzees learn about how to communicate
    through sound
