EXERCISE 1 Introduction to Lab Science, Measurement, and Chemistry INTRODUCTION This lab introduces the student to the fields of anatomy and physiology, discusses science as a general field of study, and provides a very basic introduction to chemistry. The "scientific method" is a description of a broad number of procedures and experimental techniques. The goals of valid science have criteria of experimental repeatability and prior publication rights that are followed by members of the scientific community. Terms such as hypothesis, control group, experimental group, theory, and law can help students distinguish the specific parameters of scientific study from what is commonly perceived as science by the layperson. Another important area for discussion is the topic of honesty in science. Recent court cases involving interpretation of data by "paid consultants" has blurred the objectivity of the scientific experience, yet good discussions can be had by opening-up the topics of honesty in the commercial development of new drugs and the need for honest appraisal of one's work when the efforts of science are used for purposes that concern the health or well-being of people. Another part of the lab introduces the student to the idea of data collection, working with data, graphing results, and interpreting the data in a very simple format. Some students will have no difficulty with the numerical portion of the exercise while others may feel very frustrated. It is a good time to make an early evaluation of students' proficiency in math and the potential need for math review. Some anatomy and physiology courses have chemistry as a prerequisite and some do not. This lab exercise involves some basic and fundamental concepts of chemistry but is not meant to cover even the essentials of chemistry needed for the course. A good reference source for chemistry is important for those students who have had no chemistry background. TIME 1.5-2 hours MATERIALS Acid/Base Five 10 mL test tubes
