Answers to five questions about chemistry are given. Most of the questions relate to biological chemistry. (GS)

Includes a discussion of the structure of some molecules and the design of an experiment to replace CHEM Study Experiment 7. (GS)

Describes a course designed to contribute directly to the teacher's ability to teach chemistry at the high school level with particular emphasis on planning and running a laboratory. Outlines the topics and occurrences in the course week by week. (GS)

Describes a sequence of demonstrations that may serve to initiate and maintain student interest in the development of acid-base theories and bond strength. (GS)

Describes a course which used a student project approach and was designed to replace traditional instrumental analysis. Presents the criteria used for project selection and gives examples of student projects in 1974. (GS)

Describes the insertion reaction using the insertion of carbenes into carbon-hydrogen bonds as an example. Outlines an experiment that will illustrate dihalocarbene insertions into diisopropyl ether. (GS)

Describes the use of a TV program to review regularly assigned homework in a chemistry class designed for students with a weak chemistry and/or math background. Presents student reactions, conclusions, and future plans for the TV sessions. (GS)

Describes a series of experiments designed to verify the various relationships implicit in the ideal gas equation and shows that the success of the Graham's law effusion experiments can be explained by elementary hydrodynamics. (GS)

Describes an experiment in which the beam of X-rays is simulated through the use of a laser as a monochromatic light source and the crystal is replaced by photographically prepared masks. A strong diffraction pattern as large as 20 cm. can be obtained. (GS)

Describes the desk top calculators now on the market, including manufacturers, prices, and functions performed. Provides a table of specifications for programmable desk calculators. (MLH)
