The Department of Environmental Sciences offers B.A. and B.S. degrees in Environmental Sciences. Students can choose to concentrate their studies Environmental Sciences / 273 in one of three options: Natural Science, Social Science, or Environmental Toxicology.

The necessity of maintaining an acceptable level of environmental quality is placing increasing demands upon governments and industries locally, nationally, and worldwide. To help meet those demands, the Environmental Sciences program is designed to provide training for students intending to enter environ- mental professions or for students preparing for graduate study in law, research, or teaching in a capacity that utilizes a background in the science of the human environment.

The structure of the Environmental Sciences curriculum provides a broad scope of instruction that enables students to explore the various disciplines and professions involved with solving environmental problems as well as opportunities for students to focus their training in accordance with their own educational and career objectives. All students majoring in Environmental Sciences must complete a set of “core requirements” consisting of courses that provide a basic under- standing of the physical, biological, and social sciences and their application to the analysis of environmental processes and issues. In addition to the core requirements, students must complete the required courses and an appropriate number of elective courses as designated in the option they select. Students are not expected to select an option during the freshman year so that they can be introduced to dimensions of the environmental sciences about which they may have no previous knowledge. Those wishing to change their selection of an option may do so at any time as long as they are able to complete the requirements for the bachelor’s degree within the 216-unit limit specified by the College of Natural and Agricultural Sciences.

Joint Degree Program with California State University, Fresno The Joint Degree Program with California State University, Fresno is not currently accepting new students. For more information, contact the Environmental Sciences Program Office, 3428 Pierce, (951)827-5103.

Environmental Internship Program The Environmental Internship Program offers students opportunities to work with government agencies, private firms, and nonprofit organiza- tions involved in environmental affairs. As excursions into professional life, internships provide “hands-on” experience in applying the principles presented in courses. Beyond the highly specialized training associated with on-the-job activities, students can gain insights into their aptitudes, aspirations and work habits that enable them to clarify their academic and career objectives. Professional acquaintances established during internships can continue to serve as important contacts for students after the internship is completed.

Although most internships are part-time (12–15 hours per week) positions in the Riverside area, organizations that host student interns are located throughout the United States and in Washington, D.C. Students working as interns may receive stipends, hourly wages, or serve as volunteers, depending upon the specific appointment. Up to 16 units of credit toward the bachelor’s degree may be earned by developing an academic component of the internship in consultation with a faculty supervisor and enrolling in ENSC 198-I.

Undergraduate Research Students interested in enhancing the status of knowledge about environmental processes or seeking new solutions to environmental prob- lems may gain training and experience as part- time employees in the department’s research laboratories and other research facilities, such as the Air Pollution Research Center and the U.S. Department of Agriculture Soil and Water Research Service, located on campus. Those wishing to conduct their own research under faculty supervision may earn academic credit by enrolling in ENSC 197. Expenses for both laboratory and field experiments are eligible for funding by the campus mini-grant program which supports undergraduate research and creative activity.

Environmental Toxicology Option As a curriculum that emphasizes the chemistry and biochemistry of toxic substances in the environment, this option prepares students for careers dealing with the control of toxics in the environmental media of air, water, soil, and ecosystems and in such related fields as public health and industrial hygiene. Qualified stu- dents completing this option may enter UCR’s graduate program in Environmental Toxicology without significant deficiencies in their under- graduate curriculum.

Natural Science Option As a general curriculum emphasizing the natural sciences, this option is suitable for students wishing to maintain a broad range of choices in technically oriented environmental professions such as air and water pollution control, haz- ardous materials management, public health, natural resource management, and environmen- tal impact analysis. The Natural Science option is also appropriate as background for graduate study in such disciplines as ecology, forestry, air and water science, and environmental engineer- ing. Students may earn either the B.A. or B.S. degree by completing the requirements speci- fied by the College of Natural and Agricultural Sciences.

Social Science Option Developed for students whose interests are ori- ented toward the social context of the environ- mental sciences, this option is appropriate preparation for careers dealing with environ- mental regulation, land use planning, environ- mental impact analysis and administration of environmental protection programs. The Social Science option is also suitable for those intend- ing to continue their education in such areas as natural resource economics, urban plan- ning, and environmental law. Both the B.A. and B.S. degrees are available to students in the Social Science option.

California Teach-Science/Mathematics Initiative (CaTEACH-SMI) California Teach-Science Mathematics Initiative (CaTEACH-SMI) has a goal of addressing the critical need of highly qualified K-12 science and mathematics teach- ers in California. With an economy increasingly reliant on science, technology, engineering, and mathematics (STEM) and the anticipated large scale retirement of qualified teachers, this is an essential time to explore and prepare for a career in teaching science or mathematics.

CaTEACH-SMI at UCR offers undergraduate students paid/unpaid opportunities, such as the SMI & Alpha Center Apprentice Program, to explore STEM teaching as a career option. Through CaTEACH-SMI, students receive advis- ing and mentoring to prepare for entrance into an intern teaching credential program while dili- gently coordinating with academic advisors to ensure completion of STEM degree require- ments. The CaTEACH-SMI Resource Center provides future STEM teachers with material and financial resources which includes the National Science Foundation (NSF) Noyce Scholarship Program, to promote planning and professional development towards a sci- ence/mathematics education career.

For more information about the CaTEACH-SMI program, please visit http://smi.ucr.edu or at the Resource Center at 1315 Pierce Hall.

Some of the following requirements for the major may also fulfill some of the College’s breadth requirements. Consult with a depart- ment advisor for course planning.

The major requirements for both the B.A. and the B.S. degrees in Environmental Sciences are as follows: Students must fulfill the core courses listed under the lower-division and upper- division requirements with a grade point average of 2.0 or better and no grade lower than a C-. If a grade of D or F is received in 2 or more core courses required for the major, either in separate courses or repetitions of the same course, the student may be discontinued from the major. Students must, under such circumstances, peti- tion the department to remain in the major. Students are also required to choose one of the the options and satisfactorily complete the option requirements.

Note To gain maximum benefit from participat- ing in the Undergraduate Research and Env- ironmental Internship Programs, students in- tending to enroll in ENSC 197 and ENSC 198-I should contact their advisor during the quarter prior to enrollment in these courses. 274 / Programs and Courses
