In order to earn a BS degree in Environmental Sciences students must complete:

Baccalaureate Core

The Baccalaureate Core curriculum is the foundation for students' further understanding of the modern world. Informed by natural and social sciences, arts, and humanities, the Baccalaureate Core requires students to think critically and creatively, and to synthesize ideas and information when evaluating major societal issues. It promotes understanding of interrelationships among disciplines in order to increase students' capacities as ethical citizens of an ever-changing world.

Science and Math Requirements

Environmental scientists need a solid grounding in sciences and math to enable an understanding of environmental problems and potential solutions. To that end, students complete a full year of biology and chemistry, as well as courses in calculus, statistics and physics. Some of these courses may serve as a foundation for the upper level science courses that students take in their junior and senior years.

Environmental Sciences and Humanities Core

The ENSC Core curriculum is intended to give students breadth in the field as a whole, and is divided into two categories: Natural Environmental Systems and Humans & the Environment.

  • In Natural Environmental Systems, students learn about each of the spheres of the environment: the atmosphere, biosphere, hydrosphere, and geosphere, by choosing among selected courses for each category.
  • In Humans & the Environment, students learn about the interactions of humans with the environment by taking coursework in economics, ethics and environmental ethics, environmental law and policy, and environmental management.

Experiential Learning

The Environmental Sciences (ENSC) program requires that each student complete a minimum of 3 credit hours of experiential learning related to environmental sciences. The requirement can be met with an approved internship, research experience, or approved coursework.

Environmental Sciences Specialization Option or Certificate

Students choose an area of specialization in line with their academic interests and career goals. There are nine specialization options available, as well as two certificates. All of the specializations are available online except for Alternative Energy and Environmental Science Education. In addition, students may work with an advisor to propose the use of a minor as their specialization area. Some possibilities include Renewable Materials, Environmental Safety and Health, or Bioenergy.
