Natural Science Sequences

The following is a necessarily incomplete list of sequences of courses that satisfy the requirement: "two courses are in a laboratory science with the first course prerequisite to the second course."  The exact set of courses depends on what each science department offers each semester.

Any course used for the science requirement must have an "NS" designation in the catalog (and there are some CHM, BIOS and EES courses that are not "NS" but rather "ND", meaning "not designated"). The sum of all the NS-designated science credits must be at least 12.

We list here only courses that contribute to a prequisite sequences. These sequences add up to between 7 and 9 credits. The remaining credits to reach a total of 12 may consist of any NS-designated courses.

Special note regarding EES 022: EES lists the lab (EES 022) as the prerequisite for many of its 100-level courses. However to satisfy the prerequisite sequence requirement, one cannot take only EES 022 and a follow-on 100-level course. One must also take one of the 000-level courses associated with the EES 022 lab. This is specified in detail below.  As an example, one might take EES 002 and EES 022 in one semester andEES 100 in a subsequent semester.

Earth and Environmental Science

Prior to the 2015-2016 catalog, there were a vast number of 3-credit 0-level EES courses that could be taken with the EES 022 lab, with that lab serving as the prerequisite for another vast choice of 100-level courses.  The prerequisite sequences are now restricted to a smaller set of courses as shown below.  By Lehigh rule, the catalog of year-of-entry is applied, so students in the class of 2018 are earlier are governed by the prior sequences.

EES 021 Introduction to Planet Earth (3) plus lab EES 022 Exploring Earth (1), followed by EES 131 Introduction to Rocks and Minerals (4)

EES 025 The Environment and Living Systems (3) plus lab EES 022 Exploring Earth (1) followed by EES 152 Ecology (4)

EES 026 Energy - Origins, Impacts, and Options (3 credits)

EES 028 Conservation and Biodiversity (3) plus lab EES 022 Exploring Earth (1) followed by EES 152 Ecology (4)

EES 080 Introduction to the Earth System (4, includes lab) followed by one of the following:

  • EES 115 Surficial Processes (4)
  • EES 131 Introduction to Rocks and Minerals (4)
  • EES 152 Ecology (4)
  • EES 200 Earth History (4)
