Details about this class
Beginning Fall 2025 You are required to register for the linked sections of CH221Z and CH227Z that I teach (CRN 45255 (CH221Z) CRN 45256 (CH227Z). You must be able to attend both lecture and laboratory meetings to successfully complete this course.
Welcome to CH 227Z -General Chemistry I Laboratory course.
Chemistry 227Z is the first of a laboratory course in a three term chemistry sequence designed to provide a year of general chemistry to science majors. It will meet transfer school requirements for such science majors as: chemistry, physics, chemical engineering, pre-medicine, and other pre-professional programs. The class consists of an on-campus laboratory section. The laboratory course reinforces concepts presented in the textbook and provides the student a hands-on opportunity to explore these topics.
Because this is a science major's course, the entering student should be able to demonstrate prerequisite math and chemistry skills. The student must have successfully completed CH151 or documented equivalent and must have passed college algebra (Math 111).
To help you decide if chemistry class is right for you, here is an outline of what your responsibilities will be. Each week you will have:
- Pre-laboratory assignment
- Laboratory experiments and activities
- Post-laboratory analysis assignment
Technology
There is no additional technology required for this class.
No show policy
Your instructor can mark you as a "no show" if you do not participate in your class during the first week. This will remove you from the class.
Students with disabilities
