General reactions of metals and non-metals and their compounds are also considered (includes an introduction to coordination compounds). Four hours lecture and two hours laboratory per week.


The chemistry of carbon compounds. Properties, synthesis, and reactions of saturated, unsaturated, and aromatic hydrocarbons, with emphasis on modern theoretical, mechanistic interpretations. Introduction to oxygen containing compounds. Four hours lecture and three hours laboratory per week.


A survey of the major functional classes of organic compounds including structure, nomenclature, properties, and reactions. Includes an introduction to the classes of natural products. Four hours lecture and two hours laboratory per week. Student must have completed one year of high school general chemistry.


A survey of chemistry of cellular compounds. Introduction to the different classes of biochemicals. Introduction to bioenergetics and enzymology and to the major pathways of cellular chemical events. Four hours lecture and two hours laboratory per week.


A survey of the chemistry of the earth's environment, including atmospheric chemistry, pollution and the greenhouse effect, renewable energy, hazardous and nuclear waste, and water pollution. The ethical and moral responsibilities of humans to the environment are also discussed. Four hours lecture and two hours laboratory per week.


Includes cell systems, cell cycles, cell function, energy production and metabolic systems, biological control systems, protein synthesis, and genetics. Lab included. It is recommended that the student complete one year of high school laboratory science. This course is designed for students majoring in the sciences, healthcare, or nursing.


An introduction to the meaning, ethics, and metaphysics of the human relation to various aspects of the world. Specific courses will focus on a single topic (e.g., nature, technology, culture, economics, religion.)


Survey of major animal phyla. Relationships between structure and function. Emphasis on the diversity of animal forms. Relationships of organisms with each other and with their environment. Lab included. Writing research course.


Survey of the plant kingdom and related organizsms from algae to flowering plants. Identification of campus Vascular plants. Basic life processes including photosynthesis, plant development, reproductive cycles, flowering and fruiting responses, and the ecological importance and conservation of plants. A WR emphasis with research term paper, experimental lab write-up and career development components. Lab included.


Study of living and non-living factors in biotic communities and their interaction in controlling the structure and development of various ecosystems. Principles of succession, population dynamics, and conservation. Supplemental trips may be included. Lab included.


Selected topics in biology covered on a rotating basis. Lab included with some topics. Some topics will have prerequisites (see annual class schedule).


Influence of plants on human, economic, social, and political history, and the plants people have chosen to protect and cultivate. Numerous field trips include plant production facilities, bakery, commercial greenhouse, apple orchard, farm, and meetings with resource persons working with cultivated plants. Overnight field trip(s) and weekly lab included.


Field-based course examining the forces affecting living species in Costa Rica. After a series of weekly on-campus meetings to review basic ecology and human culture of Costa Rica, students will travel during spring break for an 8-day field trip to Costa Rica. Traveling by motor coach and boat, the course will examine high altitude volcanic effects, mountain tropical forest habitat, and low-land tropical forest along the Pacific Ocean in southwest Costa Rica. A pre-trip presentation, personal journal/species field notebook, participation, post trip meetings, and a term paper will comprise the majority of student assessment. A course trip fee over and above tuition will be assessed. Valid passport and instructor consent is required.


Experiential trip courses offered on a rotating basis. Past examples include "Ecology of the Boreal Forest", "Prairie and Ranch Resources", and "Ecology of Iceland." Variable fees over and above tuition will be assessed to cover the cost of travel. Travel documents such as passport/visa may be required.


The course is designed to provide students an experiential learning opportunity about the ecology and culture and their interaction in a selected country of Asia. Special focus will be placed on how culture developed in adaptation to the local ecosystem and the environmental issues that the local population currently faces. Interaction with local scholars, experts, and students will provide perspectives. This course includes a mandatory trip. During the trip, students are required to participate in observation, discussions and related activities. A course trip fee over and above tuition will be assessed. Valid passport is required.


This course examines the efforts to understand biological origins and diversity. Patterns and principles of biodiversity and the significance of diversity will be considered. Emphasis will be placed on the principles and process of evolution rather than on the products of evolution. The class will include lecture, discussion, and workshop elements.


A survey of the native spring wildflowers, common trees and shrubs of the Great Lakes Region. Particular attention will be given to the use of taxonomic keys and field guides in field identification as well as information on the general ecology of each species.
