II. Summary of the Lessons

 Movements of Animals

•   Animals move around to find food, water, and shelter.
• Some animals move to run away from other animals that may harm the
• Other animals move to look for a partner and reproduce.

Below are the list of animal movements and the parts use in moving.

A.  RUN/WALK - legs   

B.  LEAP or HOP – legs

C.  CLIMB – limbs

D.  GLIDE

Examples:

 Flying Squirrel – It uses its loose skin between its front and back legs which helps it glide through the air.

Flying fish – Its large, wing like fins enable it to glide as it comes to the surface of the water

E.  CRAWL – short legs

F.  CREEP – muscles in their bodies

Examples:

Snake (Slither)

Worm ( Wriggle)

  Snail

G.  SWIM - Tails and Fins, Flippers, Tentacles

Examples:

 Fish

    Dolphin (flippers)

   Whale (flippers)

     Seahorse

     Octopus (tentacles)

Food Animals Eat and Ways They Get Their Food

  A.  HERBIVORES

·        Animals that eat only plants or certain plant parts

·        Animals that eat grass are called grazers. Grazers have big teeth that help them chew grass.

  B. CARNIVORES

·        Animals that eat flesh or meat of other animals.

·        Most carnivores have sharp teeth which enable them to tear meat into small pieces and chew them.

·        Many carnivores also have claws for catching and holding their prey.

·        Predator – animal that kills and eats other animals

·        Prey – animal taken by a predator as food

C.  OMNIVORES

·        Animals that eat both plants and other animals.

REPRODUCTION in ANIMALS

•     Some animals look like their parents from the time they are born 
•   Other animals go through many changes as they grow before they resemble or will look like their parents. 
•    Viviparous – animals that give birth to their young alive.
• Oviparous – animals that lay eggs     

     

CHANGES IN ANIMALS AS THEY GROW

A. Life cycle of Butterfly

 

 
B. Life cycle of Frog

ADAPTATION OF ANIMALS TO THEIR HABITAT

 

·        Animals adapt to their habitat.

·        HABITAT is a place where living things naturally live.

·        One of ways animals adapt to their habitat is through their body coverings.

·        Two parts of the body covering:

Ø  Skin protects the internal organs of an animal.

Ø  Outer covering

A. Hair or Fur
B. Feathes
C. Scales
D. Spines
E. Shells

• There are animals that do not have outer covering, such as the squid, jellyfish, worm, frog
