The physical properties of atmospheric pressure are often difficult for
students to understand in an Introduction to Physical Geography course.
Visual demonstrations can greatly aid student's comprehension of basic
concepts and lay the foundations for understanding advanced processes
involving pressure.  Entertaining demonstrations using everyday (and
cheap)
items will illustrate the following properties of pressure:
       1.  atmospheric pressure is a force
       2.  atmospheric pressure is exerted in all directions
       3.  partial pressure of oxygen (atmospheric pressure is created by
           gases)
       4.  atmospheric stability
       5.  Coriolis Force
       6.  mid-latitude cyclone motion

     This presentation is a slide show illustration of the "Four Sectors of
Economic Activity: Primary, Secondary, Tertiary and Quaternary."  The
slides were taken in 1996 in Northern California while attending the
Association of Pacific Coast Geographers Annual Conference.  They show Napa
Valley vineyards (primary), a smaller version of the Golden Gate Bridge
(secondary) at Cal State U. at Sacramento, tourism (tertiary) in Carmel,
education (tertiary and quaternary) at Stanford U. and high-technology
(quaternary) in Silicon Valley.



Educating the Public on Phosphorus Pollution in the Lake Whatcom Watershed

Abstract: GIS modeling is an ideal tool to educate both the public and policy makers concerning the issue of watershed use, development, and drinking water quality. This presentation demonstrates how a GIS based model can be an ideal tool in developing public education. The Lake Whatcom watershed supplies the city of Bellingham. A key indicator of water quality is phosphorus and is directly related to land use activities. This "phosphorus hot spots" model was developed based on local parameters and clearly indicates how increased residential expansion in the watershed has decreased a water quality indicator. Models of this nature can easily be adapted for educational uses throughout the curriculum as well as for the general public.
