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 anyNS-designated courses.

Physics  [] indicates optional 1-credit lab

PHY 11 Introductory Physics I (4) [PHY 12], PHY 21 Introductory Physics II (4) (note that PHY 21 additionally has a prerequisite of MATH 23)

PHY 10 General Physics I (4) [PHY 12], PHY 13 General Physics (3)

PHY 11 Introductory Physics I (4) [PHY 12], PHY 13 General Physics (3)

Earth and Environmental Science

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

Students who are minoring in EES may take a two-course sequence starting with EES 080, but that course is open only to EES majors and minors.
