Red Beans and Rice: Slope failure experimental modeling
I use the full-blown assignment in my sophomore level geomorphology course as a stand-alone lab. Typically, students have done some slope profiling the field before this lab.
I have a scaled-down version that I use in a large, introductory geology course.

Description of the activity/assignment
In this activity, students replicate the slope failure experiment presented by Densmore et al. (1997) in the journal Science. They are given the original article and the slope failure apparatus (along with all associated materials) and then they need to figure out how to replicate the experiment. Once they have completed an experimental run of sufficient length, they compile and analyze their data and compare it to the article's results.
After completing this portion of the lab, the students read the discussion and reply (Aalto et al., 1998; Densmore et al., 1998) and critically evaluate they results of the experiment and its applicability to the real world and landscape evolution.</P>
