Classification

11/2/2020

 
I normally begin the very short unit on classification after genetics and evolution because of the changes in how organisms have been organized with DNA and biochemical evidence now available.

I start off giving a bit of history on the classification of organisms and Carolus Linnaeus.  Then I talk about taxonomy and scientists' current understandings and classification system using the domains Bacteria, Archaea, and Eukarya.

I have my classes practices creating a dichotomous key and I give some additional information about binomial nomenclature.

Students complete several classroom activities and labs to practice following and writing dichotomous keys and learn more about the classification of organisms.  I follow with examples of phylogenetic trees and cladograms that show the evolutionary history of animals.  Videos about the evolution of vertebrate diversity (below) are shared with students as I wrap up the unit.
The Presentation and Student Notes files are available here. 

    AuthoR: 

    New York State Teacher of Biology/Living Environment

    ​All regular education and most special education students are required to take the New York State Living Environment Regents.  This is the material I have delivered to all ability levels of students to prepare them for that test.  

    My instruction of this course evolved. Although I continually "tweaked" things from year to year and class to class, I found that the most orderly delivery was to use PowerPoint slides to act as my "plan book". From these, I communicated instructional objectives, vocabulary, lab activities, and other learning activities to students.
