Title: Classification of Animals SC.3.L.15.1

Classification of AnimalsSC.3.L.15.1
  • Mary Tweedy
  • Curriculum Support Specialist
  • Dr. Millard Lightburn
  • Elementary Science Supervisor

2
Benchmarks
  • SC.3.L.15.1 - Classify animals into major groups
    (mammals, birds, reptiles, amphibians, fish,
    arthropods, vertebrates and invertebrates, those
    having live births and those which lay eggs)
    according to their physical characteristics and
    behaviors. (Cognitive Complexity Moderate)
  • SC.5.N.2.1 Recognize and explain that science is
    grounded in empirical observations that are
    testable explaining must always be linked with
    evidence. (Cognitive Complexity Moderate)

Classification
  • Do you collect baseball or Pokemon cards?
  • How about rocks or CDs?
  • If so, you probably organize the items
  • to make them easy to find.
  • Scientists have a system for keeping track of
    millions of different organisms that live on
    Earth.
  • They classify, or organize, the organisms into
    groups based on similar characteristics.

4
How do Scientists Classify Animals?
  • Write down a list of as many animals as you can
    name in one minute.
  • Look over the list. What information about these
    animals might scientists use to classify them?
  • What body covering do they have?
  • Do they have a backbone?
  • How do they breathe?
  • In the reading, Classifying Animals, well look
    at how and why animals are classified into
  • groups.

5
What are the two main groups that scientists
classify all animals into?
  • Vertebrates
  • Backbone
  • Skeletons inside their bodies, help them stand
    and move around
  • Examples
  • giraffe, people,
  • Dog, shark, bird, fish
  • Invertebrates
  • No backbone
  • Some have
  • Skeletons onside their body
  • Grow shells
  • No hard parts in or outside of their body
  • Examples
  • beetle, snail, worm

6
Look at the animals in these pictures.
Shark
Wolf
butterfly
crab
Separate them into two groups based on something
they have in common. How did you group the
animals? Did you sort them by size? Maybe you
sorted them by color or where they live. Lets
find out how a scientist sorts different animals
into groups.

Exploration Animal Classification
  • Vertebrates
  • Invertebrates

8
More on Vertebrates
  • How can vertebrates can be classified into
    groups?
  • By
  • skin covering
  • how they reproduce
  • how they maintain body temperature
  • characteristics of their limbs (arms and legs,
    or their equivalent such as wings or fins)..

9
What are the 5 Groups of Vertebrates?
  1. Fish
  2. Amphibians
  3. Reptiles
  4. Mammals
  5. Birds

10
Fish
  • Lives in water
  • Have wet scales
  • Breathe with gills
  • Some lay eggs in water

11
Amphibians
  • Lives on land and water
  • Have moist skin
  • Lay jelly coated eggs in water

12
Reptiles
  • Have dry scales
  • Lay leathery shelled eggs
  • Cold blooded

13
Mammals
  • Have hair and produce milk
  • Give birth to live offspring (no eggs)
  • Warm blooded

14
Birds
  • Have feathers
  • and hollow bones
  • Lay hard shelled eggs
  • Warm blooded

15
What are you wondering now?
  • 1. Why is a whale classified as a vertebrate?
  • 2. Compare and contrast a frog and a toad .

Is it True?
Amphibians Reptiles Fish Birds Mammals
Have a backbone
2. Have scales
3. Have smooth skin
4. Breathe with gills
5. Breathe with lungs
6. Have fur or hair
7. Have feathers
Lay eggs with hard shells
9. Feed milk to babies
21
More on Invertebrates
  • Arthropods are the largest group of invertebrates
  • What do they all share in common?
  • Jointed legs or limbs
  • Hard body covering that forms an outer skeleton
  • Examples include centipedes, millipedes, spiders,
    mites, horseshoe crabs, scorpions, crustaceans
    (lobsters) and insects

22
Why are animals grouped into different
categories?
  • Answer They are grouped into different
    categories because they use different types of
    physical features to carry out the activities
    they need to live.
  • For example, birds are grouped together because
    they have wings, feathers, and beaks, while fish
    are grouped together because they have fins,
    scales, and mouths.
  • Why are arthropods grouped together?
