Summary:
• Total 6-unit courses or equivalent = 15 (depending upon prerequisites)
• GERs satisfied: Nat Sci, Soc. Sci., Hum or Art, Q, W/S

Restrictions:
• Courses can be counted for only one category. 
• No more than 4 courses may count towards the ENSCi major and an additional major.
• ENSCi majors cannot double major with ENST.

Suggested Thematic Groupings of Courses

Below we describe groupings of courses organized around particular themes. These themes are common areas of student interest and common subfields within the environmental sciences. These are not prescriptive, rather they are intended to give students and advisors a list of courses taught at Lawrence that could be used to create a coherent course of study around a particular area of interest. Some of these courses fall outside the natural sciences and may or may not count towards the major. For example, the Sustainable Agriculture cluster includes courses in anthropology and philosophy. One of these could count towards the major under category II, but the other would not count. We list these to give a broad picture of course at Lawrence that may be thematically linked.  These clusters would appear on the ENSCi webpage.
