PLEASE NOTE: Preparing a pre-lab (writing down the goal of the activity in the reaction section, looking up the properties and hazards associated with the chemicals being used and writing them down in the materials section, and writing down a plan/procedure that will be followed in lab) in your notebook before coming to lab is an important process that will help you complete the laboratory activities successfully; thus, write-ups may be checked at the beginning of the laboratory period.

The faculty teaching this course reserve the right to unilaterally alter the schedule as needed. Any changes to the schedule will be announced in class and recorded in this document.
