Winter Field Lab: Snow Hydrology
This field activity may be implemented during late winter or early spring when things have not quite thawed. Students collect their own data from a snowpack, including measuring water equivalent, identifying types of snow metamorphism, finding evidence of precipitation patterns, and judging possible snowpack hazards. Back in the lab, students evaluate their data, draw conclusions, and make a report. This activity is designed for upper-level undergraduate and graduate-level geohydrology courses.

Magnifying and Observing Cells
Students will learn that all organisims are composed of cells, the building-blocks of life. Most cells are microscopic and must be magnified to be observed. Students will make slides of cells from an onion skin and Elodea (American or Canadian waterwee) to observe under a microscope.

The Immune System: Red Cell Agglutination in Non-Humans
This exercise presents the concepts of immunology from biochemical, evolutionary, and adaptive standpoints. While all organisms have developed some mechanism of defense against external agents, vertebrates have the most complex immune responses capable of exquisite specificity and long duration. This affords a distinct advantage to species with a relatively long life span and low fecundity. This exercise explores the relationship between immunologic stimulation of the host with foreign antigens

Uniform convergence and pointwise convergence
The aim of this material is to introduce the student to two notions of convergence for sequences of real-valued functions. The notion of pointwise convergence is relatively straightforward, but the notion of uniform convergence is more subtle. Uniform convergence is explained in terms of closed function balls and the new notion of sets absorbing sequences. The differences between the two types of convergence are illustrated with several examples. Some standard facts are also discussed: a unifo
