Courses

Current Courses

• CVEN-5323: Applied Stream Ecology Emphasizes the integration of hydrologic, chemical, and biological processes in controlling river, stream, and reservoir ecosystems at several spatial scales. Students apply ecosystem concepts to current environmental and water quality problems and learn field methods in field trips and a team project.

Past Courses

• ENVS-4800: Mineral Development in the Rockies Mineral Development in the Rockieswill address the extraction of non-renewable natural resources in the Rocky Mountain West of the United States and Canada. The course will address scientific, policy and ethical aspects of mineral resource development.
• EBIO-1220: General Biology II Provides a concentrated introduction to organisms, homeostasis, development, behavior, and ecology. Emphasizes fundamental principles, concepts, facts, and questions reenforced through lab exercises
• ATOC-1050: Weather and Atmosphere http://atoc.colorado.edu/~saraht/atoc1050/
  ntroduces principles of modern meteorology for nonscience majors, with emphasis on scientific and human issues associated with severe weather events.
• ENVS-3173: Creative Climate Change Communication The objectives for this course are (1) to generate multimodal compositions and (2) engage with various dimensions associated with the environment and sustainability. We also work to deepen our understanding of how issues can be expressed using innovative communication techniques such as as sketch comedy.
• : Ecosystem Field Studies (Colorado) http://www.ecofs.org/ecofs-courses/colorado-course/rocky-mountain-field-study
  This 3-week outdoor course focuses on experiential & applicable scientific field research methods. Instruction is delivered with active, inquiry-based activities incorporating observation & data collection, small working groups, lecture, focused exploration & spectacular off-site ecosystem trips. Students create and implement an original field research project to culminate the class.
