Soil Properties and Geomorphology
University of South Dakota
This activity has benefited from input from faculty educators beyond the author through a review and suggestion process.
This review took place as a part of a faculty professional development workshop where groups of faculty reviewed each others' activities and offered feedback and ideas for improvements. To learn more about the process On the Cutting Edge uses for activity review, see http://serc.carleton.edu/NAGTWorkshops/review.html.

Description of the activity/assignment
To prepare for this exercise, the students have been lectured on soil formation and on a field trip, described a simple soil within loess. Here, the students use data collected from a chronosequence to compare the relative age and amount of soil formation on a series of fluvial terraces. The students are to insert the data into a graphic program and generate specific graphs of soil properties. The students then interpret the amount of soil formation compared to the relative age of the fluvial terraces. Finally, the students assess how the 5 soil forming factors (climate, organisms, relief, parent material, and time) influenced soil formation in this setting.
Designed for a geomorphology course
Determining whether students have met the goals
The students turn in their answers, along with a copy of the graphs that they plotted. I check for accuracy of the graphs (some calculations are required) and for the quality and accuracy of their answers.

This assignment is borrowed from other geomorphology lab instructors. I turned it into a homework assignment. The data is from Les McFadden's master's thesis (McFadden, 1978).
