Sandra Burkett (Section 01)
Patricia B. O'Hara (Section 01)


This course examines the structure of matter from both a microscopic and macroscopic viewpoint. We begin with a detailed discussion of the physical structure of atoms, followed by an analysis of how the interactions between atoms lead to the formation of molecules. The relationship between the structures of molecular compounds and their properties is then described. Experiments in the laboratory component provide experience in conducting quantitative chemical measurements and illustrate principles discussed in the lectures.

Placement into CHEM 151 is determined by the chemistry department.

For Fall 2020 and Spring 2021: The course will involve asynchronous online lectures and synchronous online small-group problem-solving sessions and labs.  There may be some opportunities for small-group in-person interaction with instructors and other students as health and safety considerations permit. Small-group sessions will have 20 or fewer students.  Within these sessions, specific student groupings and activities are designed to foster interaction and community. 

Fall and Spring Semesters: Professors O'Hara and Burkett.

If Overenrolled: In the spring, preference is given to Amherst College first-year students.
