The Kankapot Creek Coast Guard: Public service through water quality monitoring of a stressed stream
The Biology Department at the University of Wisconsin -- Fox Valley is carrying out a long-term project in which students gather water quality data on a nearby impaired stream. These data will eventually be used to help formulate a restoration plan for the stream. This exercise follows the procedures our students use to assess stream habitat quality, chemical and physical parameters, and benthic macroinvertebrate diversity and pollution tolerance. Data collection is completed in the field using

The Power of Genetics: Using Classical and Molecular Genetics to Study "Real" Developmental Phenomen
The goal of this laboratory exercise is to provide a laboratory experience for undergraduates, in which they apply fundamental genetic principles to the study of a complex developmental process, specifically, root cell shape determination in the simple plant Arabidopsis thaliana. In this exercise, students identify putative root cell shape mutants, analyze an F2 segregating population, and finally use molecular techniques to determine where a specific mutation in located within the genome. This

Use PCR and a Single Hair to Produce a "DNA Fingerprint"
As a former student once commented, "PCR is the sliced bread of molecular biology". Polymerase Chain Reaction (PCR) is a process that allows an investigator to amplify a portion of a single piece of DNA into over one billion copies. We have used PCR with our Introductory Biology students to generate a simple "DNA fingerprint". This exercise will outline all the steps required to generate a DNA fingerprint for each student during two lab meetings. This article covers the background information co

21L.701 Literary Interpretation: Literature and Urban Experience (MIT)
Alienation, overcrowding, sensory overload, homelessness, criminality, violence, loneliness, sprawl, blight. How have the realities of city living influenced literature's formal and thematic techniques? How useful is it to think of literature as its own kind of "map" of urban space? Are cities too grand, heterogeneous, and shifting to be captured by writers? In this seminar we will seek answers to these questions in key city literature, and in theoretical works that endeavor to understand the cu
