Course DescriptionExamines structure and function of Oregon forest ecosystems. Covers distribution and interactions of plants, animals, microorganisms, climate and basic geology. Laboratory emphasizes identification and environmental testing. Prerequisites: WR 115, RD 115 and MTH 20 or equivalent placement test scores. Audit available.
Addendum to Course Description
1. Fieldwork Statement
Fieldwork is a professional competence in many areas of Biology. Standard field practices include measurements of abiotic and biotic components. Fieldwork includes use of all the senses to make observations in natural and built environments. Field training may include developing skills in site characterization, measurement and data collection, application of key terms and concepts, species identification, and observation. Certain protocols may require use of equipment, chemicals, and expensive gear. Field training is experiential often leading to unique sets of observations/data in particular locations. Fieldwork may include inherent risks (uneven terrain, off-trail work with map & compass, variable weather, insects, environmental irritants, travel, stress, etc.). Fieldwork can be physically challenging and may require overland travel on foot or unusual means to field points, carrying field equipment (as well as food, water, and safety equipment), taking measurements under duress (learning new protocols, requiring remaining in an unusual posture or position for a length of time, timing pressures for certain procedures, holding organisms, variable weather, etc.), survival skills, orienteering, and so on.
2. Evolution Statement
To clarify the teaching of evolution and its place in the classroom, the Portland Community College Science 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.
A. Science is a fundamentally nondogmatic and self-correcting investigatory process. In science, a theory is neither a guess, a dogma, nor a 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.
B. 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).
Science 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
A student will collaboratively and independently:
- Use basic principles of ecosystems structure and function to characterize a specific forest.
- Identify and express how humans interact with the forest environment by applying basic principles of forest management.
- Work with a team to initialize and complete a study of the biology, chemistry and physical characteristics of a forest.
Outcome Assessment Strategies
- Essay and multiple choice exams
- Maintain a detailed field and laboratory notebook
- Weekly applications of laboratory and field experiences
- Self-assessment of group dynamics
