A popular course for non-science majors is PHYS 115, You are Here:  Earth and Space Sciences.  This course studies aspects of astronomy, geology, hydrology, and meteorology, and how these fields are part of our daily lives. The focus of last week's lab, in Dr. Candice Duncan's class, was to learn the importance of contour maps and the information they provide, particularly, understanding that the numbers on contour maps represent elevation, and how to read a topographic map.  The students identified the highest and lowest elevation on the map and explained what the values meant.  Finally, they were asked to create their own contour lines given a map with streams and select elevations recorded.
