Addendum to Course Description
Fieldwork is a professional competence in many areas of Environmental Studies. Standard field practices include measurements of abiotic and biotic components in a variety of environmental conditions and habitat types. Fieldwork includes use of all the senses to make observations in natural and built environments. Field training may include developing skills in site characterization, application of key terms and concepts, species identification, and measurement and data collection using appropriate equipment. Fieldwork may include inherent risks (uneven terrain, off-trail work with map & compass, variable weather, insects, environmental irritants, travel, stress, etc.).
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.
• 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).
Science (ESR) 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 ESR 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:
- Describe the basic elements of environmental chemistry graphically, orally, and/or in writing.
- Identify different types of pollutants and their impact on humans and ecosystems.
- Evaluate chemicals and their associated impacts by utilizing scientific data, research, and/or case studies.
- Utilize basic field and laboratory methods and technologies to measure and describe chemicals in the environment.
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
ESR 172, Environmental Science: Chemical Perspectives, prepares students for life as members of an informed society, with the ability to understand and to continue learning about issues related to our natural environment. Inquiries about water and water pollution, environmental hazards and human health, pests and pest control, solid waste, hazardous waste and air pollution are the basis of this course, and are used as a platform for practicing both qualitative and quantitative reasoning. Laboratory and field investigations allow students to develop skills in scientific information-gathering, developing hypotheses, and discerning the meaning of facts and data. Relevance to our everyday lives- personal, professional, and as members of a community, is revealed as we anchor environmental topics to the theme of sustainability. By identifying ways in which our decisions and actions affect the living world, this course promotes an understanding of community and environmental implications, so that students may make informed decisions about how to use and manage natural resources in ways that preserve natural capital and support biodiversity.
