Catalog Course Description

A principles of biology course designed for biology majors and pre-med students. Detailed study of the structure and function of living material, with emphasis on the diversity of living material, animal and plant form, function, reproduction and development, evolution, and ecological relationships. 72 lecture hours, 54 lab hours.

Course Objectives

  • integrate life processes throughout the different levels of organization: atomic-molecular through ecosystems and the biosphere
  • identify the function and structure of the various plant bodies
  • demonstrate a thorough understanding of form and function in plants and animals
  • demonstrate a general appreciation for the diversity of life forms
  • demonstrate a thorough understanding of plant and animal reproductive processess
  • describe in depth the structural detail of cells and organisms, and to analyze the relationship of this structure to normal function
  • compare processes of reproduction and development in representative groups of organisms
  • compare major organ systems in representative organisms
  • demonstrate a thorough understanding of the basic biological principles important for success in more advanced biology courses
  • demonstrate an ability to use equipment commonly available in a teaching biological laboratory
  • follow experimental procedures, and gather, analyze and present data in an organized, meaningful manner
  • recognize those emergent properties that are appropriate for a given evolutionary transition in both vertebrates and invertebrates
  • analyze a scientific hypothesis on the basis of objective criteria

Suggested Reading Other Than Required Textbook

Reading as recommended by the course schedule from the required textbook.

Examples of Required Writing Assignments

Lab notebooks and papers. Also written responses required on quizzes and exams.
Example: Lab notebooks
Lab notebooks will be based on the laboratory experiments. The notebook will consist of the following sections: objectives, materials and methods, results, and conclusion.
Prior to the lab, students are required to read the lab protocol, and write the objectives and any hypotheses. They will also briefly write down the materials and methods in preparation for the lab.
During the lab, students will keep an active record of the data they obtain.
At the end of the lab, students will be required to critically think about their data and write their conclusion in their lab notebook, including any issues they encountered during the experiment.

Examples of Outside Assignments

Students are required to present a 10 minute presentation on a topic selected at the beginning of the semester. The presentation must be supported with either PowerPoint or html. The student must account for the reliability of sources that they accessed to prepare and the relevance to our class and to biology as a field.
Students are required to look up and review primary research articles related to course concepts and make either oral or written presentations on the articles.
Students are required to complete practice questions using on-line resources that accompany the textbook.
