Sharon AP Biology Taxonomy Wiki-site ** The unity and diversity of life ** An Understanding by Design Unit For AP Biology Sharon High School Teacher: James Dixon

This Wikipedia has been created by the AP Biology students of Sharon High School. The AP curriculum requires a great breadth of knowledge about the diversity of life. Students must develop an understanding the levels of classification, the use of classification schemes, the species concept, and the diagnostic characteristics of the various major taxa of life. This last area is a particular problem. The students come in with very little background and the coverage of the material is broad but not deep. At its worst, it can be just a list of characteristics. At its best, we can examine the strategies in which all the taxa of life face common problems of existence. This assignment is part of a unit on the unity and diversity of life and provided a means to address the topic of the characteristics of the taxon. Each student was assigned a particular taxa. The student used the textbook as a source and prepared the page for the taxon including basic information about each topic. Students then had to edit the pages. Each student was required to supply one edit per page. They were to add information from internet sources and supply the links. Each student was allowed to supply up to 5 pictures (up to one per page) and up to 5 review questions (up to one per page). This editing process required the students to read each page and research the taxon for more information. In this way, the students were each developing some deeper knowledge about one taxon and familiarity with the other taxa. While this is not ideal for a zoology or botany class, it is the correct level of understanding for the AP Biology curriculum. During this process of entering information and editing, I was able to monitor the students’ work by checking the history for the wiki. The students were also able to easily email me and each other. While anyone can view these pages, only students in this course have permission to write or edit on this wiki. I asked students to initial any edits. The topics for each taxa and the assessment rubric are included as pages on the wiki. While the students worked on the wiki mostly at home, we used class time to examine the definition of species through a case study and work with phylogenetic trees and relationships. // AP Biology Themes (all addressed in part): // I. Science as a Process II. Evolution III. Energy Transfer IV. Continuity and Change V. Relationship of Structure to Function VI. Regulation VII. Interdependence in Nature VIII. Science, Technology, and Society // MCAS: // 2.3 Use cellular evidence (such as cell structure, cell number, and cell reproduction) and modes of nutrition to describe six kingdoms (Archaebacteria, Eubacteria, Protista, Fungi, Plantae, Animalia). 4.8 Recognize that the body’s systems interact to maintain homeostasis. Describe the basic function of a physiological feedback loop. 5.1 Explain how evolution is demonstrated by evidence from the fossil record, comparative anatomy, genetics, molecular biology, and examples of natural selection. 5.2 Describe species as reproductively distinct groups of organisms. Recognize that species are further classified into a hierarchical taxonomic system (kingdom, phylum, class, order, family, genus, species) based on morphological, behavioral, and molecular similarities. Describe the role that geographic isolation can play in speciation. 5.3 Explain how evolution through natural selection can result in changes in biodiversity through the increase or decrease of genetic diversity from a population. · How can we use categorization and hierarchical thinking to make sense of the vast diversity of living species? · How can different anatomical and physiological strategies help organisms meet the same challenges of life? · How can the concept of definition be applied to the species concept? · Does our organizational system for the diversity of life imply evolutionary relationship? ** Understandings: ** · Organisms are placed in various taxa based on diagnostic characteristics. · Evolutionary relationships can be implied but not proven by classification. · Classification is based on human decisions. · The definition of species is problematic. · All organisms face similar challenges of life but employ a wide array of anatomical and physiological strategies to meet these strategies. · These strategies are based on environment and evolutionary history. ** Students will know: ** · The various levels of phylogenetic organization. · How diagnostic characteristics are used to organize organisms into categories. · The various definitions for species and the problems with each. · Explain the various modes of speciation. · Explain the various modes of reproductive isolation. · Describe how evolutionary relationships are determined by using various forms of evidence. <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· The diagnostic and other important characteristics of selected major taxa. ** Students will be able to do: ** <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Interpret phylogentic trees and cladograms. <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Apply genetic, morphological, ecological and behavioral evidence to classifying organisms and determining evolutionary relationships. <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Write to and edit wiki pages <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· The Unity and Diversity of Life Wikipedia project <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Unit exam <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Creating and interpreting cladograms activity <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· “What is a species?” case study/web quest <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Discussion of classification conundrums (vultures, slime molds etc.). <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Computer lab for wiki intro and set-up. <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Discussion of cladograms and phylogenetic trees. <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Cladogram activity. <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· “What is a species?” case study/web quest (3 classes). <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Discussion of speciation and reproductive isolating mechanisms. <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Evidences for evolution and evolutionary relationships. <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Sharing of wiki pages. <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Unit exam.
