Describes a group of short courses, primarily for the high school science teacher, dealing with the chemistry of drugs, food, and water pollution; and a group of short courses, primarily for the full time college student, dealing with scientific instrumental methods. (MLH)

Describes an experiment, using a soap bubble raft, intended to provide insight into the orderly packing of spherical objects and the properties of metallic crystals. Also describes a solubility product experiment which uses barium hydroxide. (MLH)

The use of atomic absorption techniques to determine heavy metals in trace amounts is demonstrated by analyzing a solution of human hair digested in nitric acid. (MLH)

Describes qualitative and quantitative experiments using ion exchange columns; after introductory exercises the students determine the total ion concentration in sea water and blood plasma. (MLH)

Describes a chemistry course for nonscientists in which the content was largely determined by the students. An opinion poll given to the students before and after the course showed a significant improvement in the students' attitude toward science. (MLH)

Describes the information processing system employed by Chemical Abstracts Service which utilizes computers to organize material from the data base, convert it to the appropriate type face and format, and photocompose it in a form suitable for conversion to offset printing plates. (GS)

The stoichiometry of the reaction between potassium chromate and barium chloride is determined by analysis of precipitates by mixing various amounts of both solutions. (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 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)

Discusses research which reveals that students are currently entering college with the lowest academic ability in the history of the College Entrance Examination program. Urges that universities and societal research groups become more involved in the investigation of higher chemical education. (MLH)

Statements of the objectives of secondary school chemistry teaching appearing in six science education journals during 1918-1972 are divided into six chronological periods and classified as knowledge, process, attitude and interest, or cultural awareness. Includes tables giving percentage rankings of the four main categories and eighteen…

Presents a fairy tale which metaphorically deals with the teaching of chemistry and the place of research and teaching in society. (MLH)
