This four-color lab manual contains 20 lab exercises, most of which can be completed within two hours and require minimal input from the instructor. To provide flexibility, instructors can vary the length of most exercises, many of which are divided into several parts, by deleting portions of the procedure without sacrificing the overall purpose of the experiment.Each exercise is cross-referenced with pages in the Starr/McMillan text and the Knapp text and follows this format: Objectives, Introduction, Materials, Procedure (with each step numbered), Pre-lab questions, and Post-lab questions.Instructors can combine black-and-white versions of this manual with selected exercises in the Shelp lab manual to make a customized one-color manual. They can also include their own exercises.
