Includes a simple technique to demonstrate Millikan's oil drop experiment, an environmental studies experiment to measure dissolved oxygen in water samples, and a technique to demonstrate action-reaction. Science materials described are the Pol-A-Star Tomiscope, Nuffield chemistry film loops, air pucks and pH meters. (JR)

Discusses the practice of assigning questions from different publications each week as part of regular homework in a two-quarter instrumental analysis course. Concludes that students not only acquire factual knowledge but also experience the utilization of literature sources from this training. (CC)

Outlines a laboratory course entitled Inorganic Chemistry for Biological Sciences'' which is designed primarily for juniors in biochemistry, physiology, and soil sciences. Inclusion of relevant environmental topics is indicated. (CC)

Studied the effectiveness of using student's scores gained in previous courses or examinations as predictor of his further study. Concluded that determination of cut-off values on the Toledo Chemistry Placement Examination was not favored while a specific prerequisite chemistry course was proved capable of predicting student's success. (CC)

Analyzes trends in the research and development spending on the basis of a survey of chemical makers made by the Chemical and Engineering News. Indicates the presence of a modest upturn in 1973 in the basic chemical industry even in constant dollar terms. (CC)

Summarizes the thermodynamics of macromolecular systems, including theories and experiments of cyclic energy conversion with rubber and collagen as working substances. Indicates that an early introduction into the concept of chemical potential and solution thermodynamics is made possible through the study of the cyclic processes. (CC)

Describes simple quantitative determinations for ethanol and carbon dioxide, together with techniques for examining the effects of a number of environmental factors on their production. The experimental work centers around the growth of a cell population of yeast, and is suitable for senior high school students. (JR)

A course for superior freshmen for both science and liberal arts majors that satisfies the freshman chemistry requirement is discussed. It has been taught for six years and utilizes the new math'' which is based on the elementary concept of a set. A syllabus for the two semesters is included. (DF)

Limitations of classical mechanics in understanding molecular properties are discussed. Modifications introduced by quantum mechanics enable the instructor to include and integrate important concepts from thermodynamics, quantum mechanics, spectroscopy, and statistics. (DF)

Describes various parts of a mini car and their chemical composition. Useful information is included for science teachers to relate basic chemistry concepts and techniques with their application in automobile industry. (PS)

Describes some laboratory experiments that can strengthen the study of non-aqueous ionizing solvents in Nuffield A-level chemistry course. (PS)
