A Field View of Soil - Digging Around
The purpose of this resource is to understand that variations in landscape can affect soil properties. Students investigate variations in the soils around their school to discover that soil properties like moisture and temperature exhibit considerable variability across a single landscape. They also identify factors such as slope, shade, plants, compaction, which affect the appearance of soils and their ability to hold moisture.

Mating preference in the commercially imported bumblebee species Bombus terrestris in Britain (Hymen
Commercial trade of bumblebees in Europe results in different subspecies of Bombus terrestris being shipped into regions where they are not native. Although previous studies have shown that these subspecies will interbreed, none have assessed mating preference of the different populations. This study examines the mating preferences between two geographically isolated populations of B. terrestris which have unnaturally been brought together through the commercial trade in bumblebees.

The Evolution of Cooperative Behavior
In this exercise students investigate the possibility of cooperative behavior to arise among unrelated individuals even in the presence of selfish individuals or individuals that do not care for the well- being of other organisms with which they interact. Is it possible for individuals to obtain the benefits of mutual cooperation but at the same time protect themselves from cheaters? Students play a game among themselves where they use a number of different strategies that are either cooperative

The Good and the Bad: Symbiotic Organisms from Selected Hosts
Symbiosis is defined as one organism living on, in, or with another organism. Three primary categories are mutualism (both organisms benefit), commensalism (commensal benefits and host not affected), and parasitism (parasite benefits and host harmed). Hands-on dissection of host animals provides examples ...

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

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.
