Describes a demonstration that illustrates the red chemiluminescence due to singlet molecular oxygen that can be observed when aqueous solutions of hypochlorite ion and hydrogen peroxide are mixed. (MLH)

Describes the use of integrated circuit voltage regulators in electrolytic titration instruments. (MLH)

Discusses a chemistry course, taught by the Keller Plan, that includes only students who have received a D or F in a previous chemistry course. (MLH)

Presents a computational method based on a Monte Carlo generation of a large number of chemical reactions. The reactions are allowed to proceed on the basis of relative probabilities. (MLH)

Described are eight chemistry experiments and demonstrations applicable to introductory chemistry courses. Activities include: measure of lattice enthalpy, Le Chatelier's principle, decarboxylation of soap, use of pocket calculators in pH measurement, and making nylon. (SL)

Presents various statistics related to the chemical job market, including an increased number of employer recruiters, job offers, and bachelor-level chemistry graduates. (MLH)

Describes two demonstrations: one that illustrates the attainment of equilibrium in first-order reactions by changing the volumes of two beakers of water at a specified rate, and another that illustrates the role of indicators in showing pH changes in buffer solutions. (MLH)

An attempt was made to identify student characteristics which might lead to greater achievement for an individualized treatment. (Editor)

Part one of a three part report on the historical development of curriculum guidelines for the instruction of chemistry in secondary schools. Part one covers the period 1893-1920. Parts two and three appear in November and December issues of School Science and Mathematics. (SL)

Described are the development, materials, and use of English developed science activities for junior high schools, the Nuffield Combined Science Themes for the Middle Years. The program, when completed will present 24 themes including: color, water, air, plastics, metals, insects, food, light, and electricity. (SL)

Describes several chemistry projects, including solubility, formula for magnesium oxide, dissociation of dinitrogen tetroxide, use of 1-chloro-2, 4-dinitrobenzene, migration of ions, heats of neutralizations, use of pocket calculators, sonic cleaning, oxidation states of manganese, and cell potentials. Includes an extract from Chemical Age on…

The third in a series of four articles, this report includes data on questionnaires given to teachers and students regarding attitudes toward the Nuffield advanced chemistry curriculum and examinations. Data were subgrouped according to mathematics background, science background, and sex of student. (CS)

Summarizes the recommendations of a Conference centered on new approaches in the professional training of chemists. Recommendations are for three areas of higher and inservice education: curriculum, industry-academe interaction, and career programs. (MLH)

Describes a series of 10 courses, funded by the National Science Foundation, that are aimed at individualized teaching of chemists or chemical engineers working in industry through the use of multimedia instruction. (MLH)

Described are science experiments which utilize methylene blue to demonstrate the effects of pH, temperature inhibitors, and concentration on enzyme reactions in yeast enzyme systems. (SL)
