Classification!

3. Binomial Nomenclature
Two-word naming system
Genus
Noun, Capitalized, Underlined or Italicized
Species
Descriptive, Lower Case, Underlined or Italicized

4. Common name: Robin
Erithacus rubicula
Turdus migratorus

5. Common name: Black and Polar Bear

Ursus maritimus

6. The Science of Classification
Scientist who classify or
organize organisms
(animals and plants)
are called taxonomists.
Taxonomists study taxonomy.

7. What is Classification?
Classification arranges
objects, ideas,
or information
into groups by finding
common
traits or characteristics.

8. Engage Activity: Classification
Get to a table, take a baggy and classify the items into 2 groups.
Write down the characteristics for each group.
Split those groups into 2 groups.
Write down the common characteristics for those new groups.
Share - compare with the group next to you.
Are your groups: the same, similar or different?

9. In order to make their job easier, scientists classify living things into groups, based on how they are the same, and how they are different.

10. Cladograms are used to…
Organize organisms based on evolutionary relationships.
In other words…
who is related to who and where did we come from…

11. On your paper: K- P- C- O- F- G- s-

12. Groups are also arranged in
hierarchical order.

15. King Philip Come Over For Grape Soda
Activity - Mnemonic
On the KPCOFGS of paper, create your own sentence to help you remember the order of classification.
my example:
King Philip Come Over For Grape Soda

16. What are Dichotomous Keys?
a method for determining the identity of something (like the name of a butterfly, a plant, a lichen, or a rock) by going through a series of choices that leads the user to the correct name of the item.
Dichotomous means "divided in two parts".

17. Using a dichotomous key
At each step of the process of using the key, the user is given two choices; each alternative leads to another question until the item is identified.
1a. If the leaves are flat….go to question 4.
1b. If the leaves are needle-like….go to question 2.
2a. Are the needles in a bunch? Go to question 5
2b. Are they spread along the branch?“…pine tree
Eventually, when enough questions have been answered, the identity of the tree is revealed.

19. Why is Taxonomy Important?
New Discoveries
Unknown species discovered.
Questions
Two new discovers have been made. Living animal and fossil. Questions: What is this animal and how does it behave. Where does it fit into the big picture. How can we answer these question. Gather suggestions.
New fossil Uncovered.
How can you answer these questions?
