ENVS 207 Field & Laboratory Environmental Science • 6 Cr.
Practices current scientific methods of investigation and analysis of a variety of environmental elements. Format includes approximately equal components of field experience and laboratory exercises. Fulfills laboratory science course requirement at BC.
After completing this class, students should be able to:
- Apply the scientific method to understanding environmental issues.
- Collect representative samples of soil, water, air and biota.
- Maintain accurate and appropriate field notes.
- Explain the basic biogeochemical cycling of major elements on the earth.
- Discuss basic terminology, principles and concepts from sciences incorporated in environmental science (e.g., ecology, geology, hydrology, atmospheric science).
- Evaluate long-term costs of human practices, such as energy use, and be able to explain alternatives.
- Measure environmental variable in the biosphere, hydrosphere, atmosphere, and lithosphere including the ability to:
- Describe biodiversity, population, biomass and other ecological variables using multiple sampling methods.
- Describe water currents, turbidity, and conductivity of aquatic environments.
- Measure the gas (oxygen and carbon dioxide) content of a water sample.
- Measure pollution and toxin content an overall health of aquatic environments
- Describe the light intensity, solar radiation and wind velocity for atmospheric environments
- Measure atmospheric content of toxins and pollutants.
- Describe a soil profile and the fractions of a soil sample.
- Measure soil percolation rates.
- Measure the appearance, temperature, moisture content, density, acidity, hardness (carbonate and bicarbonate) and salinity of a soil sample.
- Measure the nitrate and ammonia content and the organic (living and nonliving) content of soil
- Measure toxins (both organic and metallic) in soil samples.
- Set up and conduct controlled experiments in the lab, to test hypothesis.
- Conduct an energy audit.
- Analyze data collected using quantitative methods and library research.
- Effectively graph data in a number of formats and interpret graphed results.
- Demonstrate ability to read topographic maps.
- Plot data on topographic maps and aerial photos and interpret the results.
- Critically review and discuss important scientific articles and newly released studies.
- Present collected data and data analysis in a concise written format.
- Efficiently communicate results of research to other students in the class; such as through presentations, written assignments, etc.
- Apply techniques learned in class to local environmental issues. For example, by conducting an environmental impact report for a local ecosystem.
- Assess the human impact on the natural environment using scientific research.
- Calculate and summarize personal impacts on the local environment.
