Taxonomy:
classifying organisms & giving them a universally accepted name

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

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

each species is assigned a two-part scientific name
Two-part: Genus & Species
What is a species?
Genius!!

12. Binominal nomenclature
Scientific name is always written in italics
First word is CAPITALIZED
Second is lowercased
Ursus arctos Ursus maritimus

Can anyone recall
K-P-C-O-F-G-S?
Kingdom
Phylum
Class
Order
Family
Genus

Binomial name

15. Dichotomous Key
Dichotomous Keys use Taxonomy to identify the species name by the organisms physical attributes
Check out my moon walk 
Goblin picture “remember the goblins?”

16. Today we are going to use a dichotomous key that specifically focuses on:
Physical attributes
Smell
Taste

17. Each group will need:
A magicalJelly bean
Dichotomous key
Sheet of paper & pencil

18. Dichotomous Key
Be careful when identifying, there are some that can surprise your taste buds
