1. Warm Up - Clean Your Room!
What are some ways that you organize things in your room?
Why do you organize them?
What other things do you organize in your life?

3. Warm Up
What might be a useful question to separate these organisms into two groups?
Is it large?
Is it beautiful?
Does it have canine teeth?
Does it have hair?

4. Classification of Living Things

5. Classification What is classification? History of Classification
Modern Classification
Classification

6. Introduction
If you were asked to create groups to place each of the organisms in, what two groups would you start with?

7. What is Classification?
Classification – grouping of things according to similar characteristics
Examples:
Parts of speech: noun, verb, adjective, adverb
Binder: LA, Math, Science, SS
Taxonomy – science of classification
Taxonomists are the scientists

8. Why Do We Classify?
Scientists classify organisms to help make sense and order of the many kinds of living things in the world.
The classification of living things makes it easier for biologists to answer many important questions, such as the following:
How many known species are there?
What are the defining characteristics of each species?
What are the relationships between these species?

9. Plant or Animal?

10. Plant or Animal?

11. History of Classification
Aristotle
Proposed the first classification system
Two groups:
Plants
Animals
Divided animals into three groups:
Fly
Swim
Walk, crawl, or run

12. History of Classification
Linnaeus
Classification based on:
Structure
Anatomy
Appearance
This is the basis of our current classification system.
Binomial nomenclature – Linnaeus’ naming system of giving every organism a two part name; scientific name
bi = two
nom = name
Genus + species

13. Levels of Classification
BrainPop Video: Classification
All living things are classified into seven major groups:
Kingdom
Phylum
Class
Order
Family
Genus
Species
Kings play cards on fat green stools.
King Phillip came over for gold and silver.
general
specific

16. Levels of Classification – pg. 2

17. Relationship Between Evolution & Classification
This branching diagram shows the similarities and differences between four mammals.
The more classification levels two organisms share, the more characteristics they have in common.
Species with similar evolutionary histories are classified more closely together.

18. Scientific Names
Binomial nomenclature – two part naming system; scientific name
Bi = two and nom = name
Genus + species
Genus (capitalized)
species (lowercase)

19. Scientific Names Usually Latin or Greek
Contain information about the organism
Ex: Tyrannosaurus rex
Tyrannosaurus = Two Greek words that mean “tyrant lizard”
rex = Latin for “king”
Sometimes, scientists have a little fun with scientific names!

20. Electrolux addisoni Ornate Sleeper-Ray (type of cartilaginous fish)
Electrolux = brand of vacuum
Addisoni = the man who found the ray

21. Sciurus carolinensis Eastern Gray Squirrel
carolinesis = the Carolinas (N and S)

22. Felidae lynx
Bobcat

23. Ursus arctos horribilis
Grizzley Bear

24. Canus lupus
Gray wolf

25. Lasiurus borealis
Red Bat

26. Ursus maritimus
Polar Bear

27. Dichotomous Keys
Dichotomous keys (aka: taxonomic key) – an identification guide that uses sequential pairs of descriptive statements to help identify organisms.
To use:
Read a pair of statements.
Decide which description is correct.
Follow the directions at the end of the statements until the organism is identified.

29. Warm Up Get your assigned textbook #:
The same number as your remote.
Answer the following question in your binder (warm-up section):
An organism is MOST closely related to another organism that is in the same
Family, but different genus
Class, but different order
Kingdom, but different phylum
Genus, but different species

30. Six Kingdoms
Archaebacteria
Eubacteria
Protists
Fungi
Plants
Animals

31. Six Kingdoms Chart:
What you need to include in this section for each of the six kingdoms:
Type of Cell
Prokaryote = NO nucleus
Eukaryote = nucleus
Number of Cells
Unicellular = one cell
Multicellular = many cells
Cell Structures
What important organelles are in the cells?
Describe their general structure.
Food & Energy
Autotroph = producer; makes its own food using the sun’s energy
Heterotroph = consumer
Reproduction
Asexual = one parent; no diversity
Sexual = two parents; diversity
Locomotion (Movement)
Do they move? If so, how?
Habitat
Where do they live?
Example Organisms
Other Information
General Info: pgs
Specific Info: Ch
Archaebacteria = Domain Archae
Eubacteria = Domain Bacteria
