Course Description

Introduces the properties of life, morphology and physiology of cells, cell chemistry, energy transformation, and the basic principles of ecology. Designed as a laboratory science course for non-biology majors. Prerequisites: WR 115, RD 115 and MTH 20 or equivalent placement test scores. Audit available.

Addendum to Course Description

To clarify the teaching of evolution and its place in the classroom, the Portland Community College Biology Departments stand by the following statements about what is science and how the theory of evolution is the major organizing theory in the discipline of the biological sciences.
 

  • Science is a fundamentally non-dogmatic and self-correcting investigatory process. In science, a theory is neither a guess, dogma, nor myth. The theories developed through scientific investigation are not decided in advance, but can be and often are modified and revised through observation and experimentation.
  • The theory of evolution meets the criteria of a scientific theory. In contrast, creation "science" is neither self-examining nor investigatory. Creation science is not considered a legitimate science, but a form of religious advocacy. This position is established by legal precedence (Webster v. New Lenox School District #122, 917 F. 2d 1004).

Biology instructors of Portland Community College will teach the theory of evolution not as absolute truth but as the most widely accepted scientific theory on the diversity of life. We, the Biology Subject Area Curriculum Committee at Portland Community College, therefore stand with such organizations as the National Association of Biology Teachers in opposing the inclusion of pseudo-sciences in our science curricula.
 

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Solve interdisciplinary problems using knowledge of biological organization, structures, and their functions.

  • Differentiate factual information from opinion and pseudoscience by practicing critical thinking methods used by scientists.

  • Assess new emerging scientific ideas using an understanding of the self-correcting nature of science.

  •  Interpret patterns in the living world using quantitative reasoning.

  • Communicate informed positions on biological issues using appropriate vocabulary.

Quantitative Reasoning

Students completing an associate degree at Portland Community College will be able to analyze questions or problems that impact the community and/or environment using quantitative information.

General education philosophy statement

Biology 101 is a laboratory science class that particularly addresses the quantitative and qualitative reasoning outcome of PCC’s general education philosophy statement. Students will analyze questions or problems that impact the community and/or environment using quantitative information. Biology 101 is a laboratory science that develops laboratory and data collection skills while learning about living things and environmental issues that affect living things, such as climate change. As students learn about living things from the atoms and molecules that make up cells to the ecosystems and biomes in which they are found, they will practice generating hypotheses and collecting data to test those hypotheses in controlled experiments. As students study cells, photosynthesis, cellular respiration, and ecology, we practice measuring variables that affect each system and the implications of these data.

Outcome Assessment Strategies

Outcome assessment strategies:

  • tests
  • oral presentations
  • papers
  • journals
  • group projects
  • practical exams
  • case studies
  • "team based"
