. Experiments relate to basic concepts of chemistry and health. Experiments are designed to illustrate the chemical principles discussed in class.
They include experiments that relate to health and medicine, and often use common materials that are familiar to students. Experiments are flexible. Each experiment includes a flexible group of sections, which allows instructors to select the sections to fit into their weekly laboratory schedule.
Lab times and comments are given for each. A detailed safety section in the preface includes a safety quiz. The aim here is to highlight the safety and equipment preparation on the first day of lab. In addition, each lab contains reminders of safety behavior. Students are reminded to wear goggles for every lab session.
Some experiments are recommended as instructor demonstrations. The experiment format provides clear instructions and evaluation. Each lab begins with a set of goals, a discussion of the topics, and examples of calculations. The report pages begin with pre-lab questions to prepare students for lab work.
Students obtain data, draw graphs, make calculations, and write conclusions about their results. Each lab contains questions and problems that require the student to discuss the experiment, make additional calculations, and use critical thinking to apply concepts to real life. Stockroom preparation of chemicals. Materials for each experiment are listed in the appendix with amounts given for 20 students working in pairs. Most lab sessions use standard lab equipment and chemicals that are readily available and inexpensive.
In some cases students bring samples from home. Pre-Lab Study Questions are provided on a separate page at the beginning of each laboratory report section. These questions should be completed before students come to lab. Instructors may require that students hand in the study questions before beginning laboratory work.
If so, it is easy to remove the Pre-Lab section from the lab manual. Table of Contents PART I: DRY LABS D-1 Conversion Factors in Calculations A. Rounding Off B. Significant Figures in Calculations C. Conversion Factors for Length D. Conversion Factors for Volume E. Conversion Factors for Mass F.
