Presented is a science activity in which the student investigates methods of calibration of a simple conductivity meter via a hands-on inquiry technique. Conductivity is mathematically compared to salinity using a point slope formula and graphical techniques. Sample solutions of unknown salinity are provided so that the students can sharpen their…

Presented is a review of the development of the science of pharmacology, the study of the interaction of chemical agents with living matter. The origins of the field are traced from 17th century Europe to the present, with major emphasis upon the scientists and developments made in the field in the United States. (SL)

This publication is intended to aid in the planning and implementation of Advanced Placement (AP) chemistry courses. Included are reports from high schools that have established such courses concerning costs, facilities, and instructional requirements. Also included are the free-response sections of the 1974 and 1975 AP Chemistry Examination,…

Describes an undergraduate atomic absorption experiment in which the iron and manganese concentrations in dry cat food are determined. (MLH)

Discusses the problem of choosing the proper unit (e.g., class or individual student) for the statistical analysis of educational research. Describes a study that was statistically analyzed eight different ways and discusses the various results and implications. Suggests that the problem of selecting the proper experimental unit may be less…

After receiving creativity instruction in how to approach laboratory problems, a group of college chemistry students made significant improvements in both laboratory technique and creativity as shown on an instrument designed for this study. (MLH)

Presents the results of a questionnaire administered to college chemistry students; the questionnaire contained a list of 33 aims of chemistry course that were rated by the students according to importance. (MLH)

Describes an inexpensive apparatus used to study the kinetics of fast reactions. Suggests an appropriate reaction for study, and laboratory techniques. (MLH)

Describes ion-exchange methods for the qualitative determination of iron (III), chromium (III), aluminum (III), and manganese (III) and (IV) in the presence of phosphates. (MLH)

Describes the Training in Education for Assistants in Chemistry (TEACH) program, which provides written and videotape materials to departments of chemistry for training their teaching assistants. (MLH)

Describes a chemistry project in which lichens are identified by the analysis of the phenolic substances that they biosynthesize. (MLH)

Suggests the use of simulations, games, and case studies to make chemistry more appealing and interesting to secondary level students who range greatly in motivation and aptitude. (MLH)

Presents the use of quantity calculus in calculations arising in volumetric analysis and in the more general field of chemical stoichiometrics. (HM)

This paper describes an experiment designed to reveal the consequences of the development of a concentration boundary layer. The rate of a mass transfer limited electrochemical reaction is measured and used to obtain the dependence of average Sherwood number on Reynolds number and entrance length. (Author/BB)

The attitudes of Belgian chemistry students who had chosen their area of specialization, toward organic, physical, inorganic, or analytical chemistry or biochemistry, were measured. Major differences were found in the activity attitudes rather than in the evaluative or potency attitudes. Area of specialization does not seem to correspond to…
