2. Agenda Introductory Activity - Classifying Aliens!
The History of Taxonomy and Linnaean Taxonomical Levels
Dichotomous Keys and Taxonomy
Activity - Baggie Cladistics
Consolidation Activity – Classifying You!

3. Curriculum Expectations
B2.1 Use appropriate terminology related to biodiversity.
B2.4 Create and apply a dichotomous key to identify and classify organisms from each of the kingdoms.
B3.1 Explain the fundamental principles of taxonomy and phylogeny by defining concepts of taxonomic rank and relationship, such as genus, species, and taxon.
B3.3 Describe unifying and distinguishing anatomical and physiological characteristics of representative organisms from each of the kingdoms.

4. Learning goals
Using only physical characteristics, create a taxonomic scheme to classify a group of generic organisms.
Describe the history of taxonomy and why we came to use the Linnaean system.
Describe the principles of taxonomy and be able to describe the various taxonomical levels.
Compare and contrast the physical and metabolic characteristics of several organisms and create a dichotomous key/cladogram with this information.

5. Classifying Aliens
Once you are given your handout, work with your group to come up with a way to classify the aliens!
Discuss the questions provided for you when you finish!

6. Classifying Aliens

7. What is biological Classification?
The systematic grouping of organisms into biological categories based on metabolism, and physical and evolutionary relationships.
Producer
Herbivore
Carnivore
Scavenger
Heterotroph
Autotroph

8. How do we classify organisms?
Aristotle was the first to give detailed classification of living things.
He made no effort to classify plants or fungi.
His ideas were based on the scala natura (Natural Ladder).
Animals were classified as being “sky- dwelling”, “water-dwelling”, or “land dwelling”.

9. How do we classify organisms?
The father of modern taxonomy is Carulos Linnaeus.
Had the idea to distinguish nomenclature from description.
Replaced long, traditional names with a simple two-name system (binomial nomenclature).
These were later grouped into hierarchies such as class, order, and so on.
There have been slight modifications but this system is still used in modern taxonomy.

Most basic taxonomic rank

12. Naming species

13. Baggie cLADISTICS
Follow the instructions on the handout to create a cladogram!

14. Classifying you!
Create a dichotomous key for all the members of your group!
Start with the most general characteristics that you all share , and then begin to separate based off of your different characteristics, until each of you are a single species.
Come up with a Genus and Species name for the species that is you (i.e Camreus yakeley, Hayesean kristen)
