Discusses: how thought experiments (TES) are presented and used in physics textbooks; how and why teachers include TES in their explanations; and what understandings students draw from TES. Indicates that TES are only one of a broad class of "acts of imagination" which are essential in physics education. (JN)

Gel filtration is a form of liquid chromatography that separates molecules primarily on the basis of their size. Advantages of using this technique, theoretical aspects, and experiments (including procedures used) are discussed. Several questions for students to answer (with answers) are also provided. (JN)

In the applications of instrumental analysis lessons, advanced instruments with the needed experiments are needed. During the lessons it is a fact that the more experiments are performed, the more learning will be. For this reason, experiments that do not last long and should be performed with more simple instruments and that increase students"…

Describes a course at Michigan State University in which students carry out self-experiments in nutrition. Self-experiments help to impress students with importance of human nutrition and offer insights into problems associated with altered dietary patterns. A number of possible self-experiments in nutrition are listed. (JR)

Discusses the philosophy and operation of a self-instructional laboratory at MIT which utilizes visual materials reinforced by audio tapes and is designed to give the student a taste of how to collect, display, and interpret data. Indicates that the approach results in the flexibility needed to serve self-paced courses. (CC)

Ten- and 11-year-old boys and girls were taught to solve Inhelder and Piaget's pendulum problem and the results of the experiment replicated their expectation that unaided 10- and 11-year-olds do not often solve the pendulum problem. (Editor/RK)

Describes a number of experiments which give the student an opportunity to observe the effects of the electrical nature of matter without trying to explain why a given phenomenon is occurring. These experiments should be introduced before discussing the structure of atoms, and provide practical experience for later theoretical discussions. (JR)

Reports on an effort to teach poetry and not simply expose the student to it. (Editor)

Usually the textbook descriptions of analytical methods fall short of making comparisons among several methods employed for analysis. Emphasis should be placed on making decisions about using a particular method on the basis of its merits. Listed are experiments that could be used for instruction. (PS)

Applications of wheels are shown to be an invaluable tool in teaching the processes and technology of science. (DF)
