An Environmental Sciences undergraduate degree provides a rigorous education that can lead to helping to understand and resolve some of today's most challenging scientific and policy issues—including global climate change, pollution, biodiversity conservation, sustainability, and balancing resource use and preservation. To help reach these objectives, the Bachelor of Science in Environmental Sciences offers an interdisciplinary approach to environmental problem solving. As an Environmental Sciences major, a student completes course work in four general areas:
- OSU's general education courses (the baccalaureate core)
- Basic science and math
- Environmental sciences and humanities core
- A specialization area
In addition, each student completes a minimum of 3 credits of experiential learning as an internship, research, study abroad, or field course. The BS degree in Environmental Sciences provides excellent training for a variety of careers—including work with federal, state, and local agencies, industry, non-profits, and education—or for graduate school. Students can pursue the BS degree at the Corvallis campus, online through Ecampus, and at the OSU-Cascades campus.
Major Code: 657
- Identify and define concepts in the natural sciences (e.g. chemistry, atmospheric sciences, ecology, geology, oceanography, soil science).
- Identify and define concepts in the humanities and social sciences (e.g economics, environmental law, ethics, resource policy, and human-environment interaction fields like agronomy and geography).
- Integrate concepts in the natural sciences with those in the humanities and social sciences.
- Demonstrate a rigorous cross-disciplinary science base (biological, physical, and social sciences) with a deeper knowledge in a specialization area by using quantitative tools to analyze and interpret data.
- Communicate ideas clearly- orally, graphically, or in writing- to address environmental sciences issues.
- Engage in and experience the application of the environmental sciences beyond the classroom through fieldwork, participation in an internship, research, study abroad, or other forms of experiential learning.
Major Curriculum
The Environmental Sciences major requires credits in seven categories: 49 credits of baccalaureate core; 51–53 credits of basic science and math; 27–36 credits of environmental sciences and humanities; 27–31 credits of specialization; 3 credits writing intensive course; 3 credits minimum of experiential learning; and 4–53 credits of elective courses (depends on the number of baccalaureate core electives that will also meet requirements of the major).
The major requires a minimum of 32 credits combined between the Environmental Sciences and Humanities core, the Specialization, the major WIC, and Experiential Learning requirement, that are unique (not double-counted) to the Environmental Sciences Bachelor of Science.
Baccalaureate Core
The university baccalaureate core course (BCC) requirement is met with 49 credits and a writing intensive course (WIC). The environmental sciences student satisfies the general education requirement by selecting 27 unrestricted credits from the general list of approved courses and 21 credits from a restrictive list of BCC courses, which simultaneously satisfy requirements for the Environmental Sciences major. The WIC and Synthesis requirements are satisfied by courses taken as part of the environmental sciences core curriculum.
