BI222: Principles of Biology

Course Description

BI222: Principles of Biology is the second in a 3 part series of introductory biology courses that fulfill the Bacc Core Requirements for Biological Sciences Perspectives Courses. This course is a 4 credit lecture/lab course where we explore fundamental biological concepts and theories about plant and animal evolution, structure and function, transformation of energy and matter and systems at an organismal level. More specifically, we answer questions including: How do plants/animals grow, and develop? How do organisms get what they need to sustain life? How do organisms maintain homeostasis? How do organisms respond to changing internal and external environments? There are 3 hours of lecture and 3 hours of lab each week. Bi222 is offered during Winter term and Summer Session.


This course is for life science majors and pre-professional students. BI221 (C- or better) and Basic Chemistry is required prior to registration ( see catalog for specific courses that fill this requirement).

BI222 Learning Outcomes

Students will be able to:

  1. Explain mechanisms by which cells receive and respond to internal and external signals that vary through space and time. (BCLO 1, 2, & 3)
  2. Explain how structure (anatomy) relates to function (physiology). (BCLO 1, 2, & 3)
  3. Predict relationship between structure and function in novel situations. (BCLO 1, 2, & 3)
  4. Describe how biological systems detect and respond to different internal/external environmental conditions through feedback. (BCLO 1, 2, & 3)
  5. Compare and contrast solutions to shared homeostatic challenges across various forms of life. (BCLO 1, 2, & 3)

Shared Course Learning Outcomes with BI221 and BI223

  1. Generate questions and construct testable hypotheses about biological mechanisms based on observations of the natural world. (BCLO 1, 2, & 3)
  2. Design an experiment using appropriate methodology (experimental techniques, controls, data collection and analysis), reach conclusions and identify future lines of inquiry. (BCLO 1, 2, & 3)
  3. Integrate subdisciplinary concepts from within and outside biology to address complex problems. (BLCO 3)
  4. Identify ways that interdisciplinary concepts are used to explain biological phenomena. (BLCO 1 &3)
  5. Defend a viewpoint on a socio-scientific issue based on biological research. (BCLO 1, 2, & 3)
  6. Evaluate multiple representations (e.g., diagrams, physical models, mathematical relationships) by comparing the applications, strengths, and limitations of different models and their relationship to real biological systems. (BCLO 1, 2, & 3)
  7. Create models (e.g., cartoon, schematic, flow chart, interpretive dance, etc.) to demonstrate biological concepts or systems. (BCLO 1, 2, & 3)
  8. Apply quantitative skills to biological problems. (BCLO 1, 2, & 3)
  9. Explain and use mathematical relationships relevant to biology. (BCLO 1, 2, & 3)
  10. Work productively in teams with diverse perspectives.
  11. Share ideas with peers clearly and accurately using scientific conventions.
  12. Effectively communicate experimental outcomes using professional scientific formats (e.g. report, poster, presentation). (BCLO 1, 2, & 3)
  13. Read and interpret primary scientific literature. (BCLO 1, 2, & 3)
