Scientific classification is the key to organizing the millions of earthly organisms, both living and extinct. This blog is to encourage futher student discussion about the different systems of scientific classification including the Carolus Linnaeus method of binomial nomenclature and evolutionary classification using phylogenetics (Cladograms).
Introduction
Welcome to Mr. Diviacchi's classification blog. This blog will be used in conjunction with the current unit discussing scientific classification. At the bottom of the blog page you will find brief definitions on each of the categories (taxa) of scientific classifications seen in the unit. There are also a couple of example classifications for living organisms. One you should already know, homo sapiens, but the other may not be so familiar. Take a look in the lower right column at the blobfish and then feel free to feed the Carassius auratus at the bottom of the page!
Instructions
Students are required to sign in and post comments on three blog assignemtns for this unit analyzing scientific classification.
Blog Assignment 1 - KPCOFGS mnemonic
For assignment 1 develop a mnemonic for memorizing the scientific classification levels, or taxa. Remember the Classification Rap viedo that was shown in class, the link to the video is under the Relevant Links section. Please add your own, unique mnemonic as a comment to this post.
Blog Assignment 2 - provide information on a Kingdom of choice (not Animalia)
Each group was assigned one of the six living organism Kingdoms during class. The student will research and add a comment to the post for classmates to view. The student may pick any Kingdom besides Animalia and answer the following:
-Cell Type:
-Cellular Organization:
-Nutrition method:
-Three Example Organisms using binomial nomenclature. Be sure to descirbe the similarities of these organisms within this kingdom. These comments will be used in a tertiary assignment.
*Note- see teacher example using Kingdom Animalia as the first post
Blog Assignment 3 - peer analysis
Each student is to choose 2 more students and write a brief passage, 2-4 sentences, describing the relationship and similaritites of one of your organisms to a classmates. You will choose one organism from a student with the same Kingdom and then choose one organism from a student with a different Kingdom.

Blog Objective - Cladogram
This blog will enhance the learning of scientific classification from the first assignment to the last. After the third assignment is completed the teacher and students will develop a cladogram. The teacher will review the organisms researched by the students and prepare them for class discussion. Students will analyze the different features of the organisms they researched and form them into clades. The teacher will diagram the clades at the front of the class with students making their class cladogram.

Blobfish - Scientific Classification
Blobfish - Psychrolutes marcidus
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Scorpaeniformes
Family: Psychrolutidae
Genus: Psychrolutes
Species: P. marcidus
Phylum: Chordata
Class: Actinopterygii
Order: Scorpaeniformes
Family: Psychrolutidae
Genus: Psychrolutes
Species: P. marcidus
Categories
Kingdom: There are now considered 6 kingdoms - Animalia, Plantae, Protista, Fungi, Eubacteria, Archaebacteria
Phylum: Each kingdom has subsets called Phyla. In Animalia there are more than 30 phyla whereas Plantae only has 10. Phylum Chordata is the most discussed in class and includes humans, birds, reptiles and other vertebrates.
Class: Phyla divided into several classes and the examples under Chordata include Amphibians, Birds, Mammals, Fish, and Reptiles.
Order: The sceintific organization relaxes a bit in the middle levels. The Order of livings things come under contradiction among scientists. Different sources can have organisms in differing orders and families.
Families: This is where similar genuses are grouped together.
Genus: Two or more species sharing like physical traits and other characteristics. The genus is always the first part of the scientific name in bionomial nomenclature.
Species: Defines individuals that breed to produce fertile offspring. It is possible for different species to breed but the offspring remain sterile. A common example is the mule, from the mating of a donkey and horese. The species is always the second part of the scientific name and is in lower case italic letters.
