2. What are common names for this animal?
Puma, cougar, mountain lion, panther

3. What are common names for this animal?
Buzzard vs hawk vs falcon

4. Common Names Can be misleading
Crayfish
Catfish
Silverfish

5. classifying organisms & giving them a universally accepted name
Taxonomy:
classifying organisms & giving them a universally accepted name
Lets classify some goblins!

6. Classifying both living and nonliving things,
so that we better understand the world around us
Who was the first to create a system in the science world? booger
Plant lady professor hufflepuff

7. Who was the first to create a system in the science world?
Carolus Linnaeus
Botanist & Father of taxonomy
gave them all Latin names
Came up with the system in the 1700s that is still used today
Taxonomy: think teachers versus “science teachers” or biology teachers
Wizard hat on linnaeus

8. Linnaeus’s System of Classification
Organisms are classified by their: * physical structure (how they look) * evolutionary relationships (phylogeny) * genetic similarities (DNA)
* biochemical similarities
 biochemistry: structure and function of cellular components such as proteins, carbohydrates, lipids, nucleic acids and other biomolecules.

9. Professor Linnaeus Binomial nomenclature:
each species is assigned a two-part scientific name
Two-part: Genus & Species
What is a species?
Genius!!

10. Binomial nomenclature
Scientific name is always written in italics
First letter in the first word is CAPITALIZED
Second is lowercased
Ursus arctos Ursus maritimus
Add picture of grizzly and polar bear
Ask students: what do you see, by looking at these two scientific name do you think these two animals are related?

11. The categories to classify Organisms
Hierarchical classification:
Broad  specific
Kingdom
Phylum
Class
Order
Family
Genus
Species
Binomial name

12. Harry Potter Classification
Hogwarts
Houses: Slytherin, Hufflepuff, Ravenclaw, Gryffindor
Year: 1st, 2nd, 3rd, etc.
Student: Harry, Ron, Hermione
Harry Potter:
Organisms are first classified from broader categories, then are divided into more specific/similar subgroups

14. Dichotomous Key
Dichotomous Keys use Taxonomy to identify the species name by the organisms physical attributes
A step-by-step guide to identify an organism
Each step gives a choice of two descriptions.
The descriptions have to be opposites
Ex. Leaves round vs. leaves not round
Check out my moon walk 
Goblin picture “remember the goblins?”

16. Lets Classify some House Elves
8 goblins
Why would we want to classify these goblins?
Why, how, what

17. The Tree of Life evolves
A. The classification has changed since Linnaeus’s time with new evolutionary findings
B. At 1st living organisms were classified as either plant or animal, today there are more precise classifications producing 6 main Kingdoms based on cell structure, # of cells, how they get their food & movement
1. Eubacteria
2.Archaebacteria
3. Protista
4. Fungi
5. Plantae
6. Animalia

18. 3-Domain System
A. Domain is larger than a Kingdom & separates the kingdoms into major groups
1. Eukarya - protists, fungi, plants & animals
2. Bacteria – eubacteria
3. Archaea - archaebacteria

19. Kingdom Eubacteria
Prokaryotic single celled organisms that are heterotrophs (can not make own food) some can be autotrophs (make own food)
Found everywhere

20. Kingdom Archaebacteria
Prokaryotic single celled organisms that are heterotrophs while some can be autotrophs
Found only in extreme conditions hot springs, salt brines, ocean vents

21. Kingdom Protista
Eukaryotic single celled organism that either be autotrophic or heterotrophic
There are Plant-like, Animal-like & Fungi-like

22. Protists: Red Tide

23. Kingdom Fungi
Eukaryotic usually multicellular heterotrophs with cell walls that consume decaying matter
Few are unicellular bread molds

24. Kingdom Plantae
Eukaryotic multicellular autotroph (photosynthesis) organisms with cell walls

25. Kingdom Animalia
Eukaryotic multicellular heterotrophs with no cell walls
