ENVS 207 Field & Laboratory Environmental Science • 6 Cr.

Description:

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.

Outcomes:

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.
