The labs were specifically chosen with several goals in mind: a. To parallel lecture topics. b. To demonstrate important chemical principles. c. To employ the use of techniques of self-discovery and the scientific method. d. To illustrate topics that are of public interest or concern. e. To encourage the application of chemistry outside the laboratory. In keeping with these goals, (the author has) included laboratory assignments that are applicable to the real world or contain supplemental exercises that illustrate an application ... Where possible, commercial products are used, such as aspirin, antacids, etc ... Each lab begins with written objectives. Then, in an effort to increase involvement before the lab work begins, questions are posed that ask the student: a. To make predictions about the outcome of the experiment. b. To formulate a hypothesis. c. To think about a phenomenon in a specific way. d. To apply personal experience in answering a questions. -Pref.Water is the main component of this plastic, making up 96% of its mass. ...
