Course DescriptionCovers environments of freshwater streams, lakes, and marshes. Includes effects of physical and chemical factors on organisms, along with the organisms, their biological interactions and nutrient cycles. Explores ecological factors of freshwater environments and the effects of human activities on them. Prerequisites: WR 115, RD 115 and MTH 20 or equivalent placement test scores.
Addendum to Course DescriptionTo 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 nondogmatic 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).
Lab B Notes: The lab for this course has been approved as "Lab B". This means that Faculty effort in preparation and evaluation generally occurs outside of scheduled class hours. Class format is a combination of Faculty lectures and demonstrations, guided student interactions and supervised student application of lectures. Students produce written work such as lab notebooks, reports, and responses in writing to assigned questions, and the Instructor is expected to comment on and grade this written work outside of schedule class hours. This evaluation will take place on a regular basis throughout the term.
Intended Outcomes for the courseA student will collaboratively and independently:
- Use basic principles of ecosystems structure and function to characterize freshwater habitats.
- Identify and express how humans interact with the freshwater ecosystems by applying basic principles of environmental management.
- Identify and understand the biology of the various freshwater phyla.
Outcome Assessment Strategies
