The course will employ a variety of instructional methods to accomplish its objectives, including some of the following:  lecture, labs, field work, analysis and interpretation of surface weather charts and satellite images, multimedia, individual and/or team projects and small group discussions.

Course Description
This introductory Physical Geography course explores Earth's atmosphere and biosphere by examining topics ranging from day-to-day weather variations to global climate change and the distribution of plants and animals on Earth. Using an Earth-systems approach and the concepts of energy balances and radiation laws, this course seeks to answer questions such as why do certain places have particular kinds of weather? How do forecasters predict the weather? What are the causes of global climate change? Human impacts on the atmosphere and biosphere are also examined.

Learning Outcomes

At the conclusion of the course the successful student will be  able to:

  1. Describe and use the frameworks of science applicable to 1st-year physical geography.
  2. Think critically and examine climatological, meteorological and biogeographical issues in a scientific context at local, regional and global scales.
  3. Describe and explain the processes that occur within earth’s atmosphere, hydrosphere and biosphere systems, and identify and describe interactions among these systems.
  4. Communicate effectively using the language, graphical presentation methods and quantitative methods employed in physical geography.
  5. Connect theoretical applications to “real-world” observations and measurements.

Means of Assessment

The evaluation will be based on course objectives and will be carried out in accordance with Douglas College policy.  The instructor will provide a written course outline with specific evaluation criteria during the first week of classes.

 

An example of a possible evaluation scheme would be:

Laboratory Assignments 10%
Laboratory Exams 30%
Midterm Exam 25%
Final Exam 25%
Term Project 10%
Total 100%

 

 

 

 

 

Note:  This course received a standing variance from Education Council in June 2016 to allow up to a 20% lab exam during the last 14 calendar days of the semester.  This is not a final exam; it is an assessment of student learning of lab work performed in the second half of the semester.

Textbook Materials

Texts will be updated periodically. Typical examples are:
