Course Description

Covers 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. Audit available.

Intended Outcomes

A student will collaboratively and independently:

  1. Use basic principles of ecosystems structure and function to characterize freshwater habitats.
  2. Identify and express how humans interact with the freshwater ecosystems by applying basic principles of environmental management.
  3. Identify and understand the biology of the various freshwater phyla.

Outcome Assessment Strategies

  1. Essay and multiple choice exams
  2. Maintain a detailed field and laboratory notebook
  3. Weekly applications of laboratory and field experiences
  4. Self-assessment of group dynamics

Department Notes

Columbia Gorge Community College Science Department stands by the following statement about regarding science instruction:

Science is a fundamentally nondogmatic and self-correcting investigatory process. Theories (such as biological evolution and geologic time scale) are developed through scientific investigation are not decided in advance. As such, scientific theories can be and often are modified and revised through observation and experimentation. “Creation science", “Intelligent design” or similar beliefs are not considered 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).

The Science Department at Columbia Gorge Community College, therefore stands with organizations such as the National Association of Biology Teachers in opposing the inclusion of pseudo-sciences in our science curricula except to reference and/or clarify its invalidity.

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.
