Lecture and laboratory topics of a one-quarter, undergraduate course designed to introduce students to chemical principles and phenomena involving the automobile are described. (CP)

Contains contributed suggestions in the teaching of structure and bonding and reaction rates and equilibria in the Nuffield Advanced Chemistry Project. (CP)

Describes a home-based supplementary science program for elementary school age children. The program emphasizes process skill application, simple equipment, and the use of parents as experiment advisors. (CP)

Presents an experiment for determining the pH of shampoo. (SL)

Describes an experiment to introduce students to qualitative and quantitative aspects of neutron activation analysis. (SL)

Describes a process for producing terminal or internal alkynes from ketones. Recommends using the experiment to aid in understanding acid-base strength, enolate anion chemistry, reaction at carbon versus oxygen, use of polar aprotic solvents, and elimination and nucleophilic substitution reactions. (ML)

Discusses general construction principles for miniaturized laboratory glassware. Describes a prototype experimental kit that allows the carrying out of all standard laboratory operations and discusses a trial use of the equipment with students 16- to 17-years-old. (CW)

Suggests a laboratory introduction to solid-solid phase transitions, thermochromism, and color changes associated with changes in ligand coordination suitable for undergraduate students in physical and general chemistry. Describes the preparation and analysis of the experiment. (CW)

Describes an apparatus that can be used to measure low gas pressures over a range of temperature in the undergraduate teaching laboratory. Discusses an experimental procedure and theory for pressure temperature measurements with this apparatus. (CW)

To improve the testing of students' skills in performing laboratory experiments, 92 Israeli high school physics teachers participated in the development of a list of weighted laboratory skills. Sensory-motor coordination was found to be a significant measured factor. Factors affecting reliability were also noted. (GDC)

Discusses some contributions chemists can make in the investigation of crime. Describes the optical properties of materials and defines the refractive index. Explains the refractive indices for liquids and for solids, and provides laboratory exercises for determining both. (TW)

Cites reasons why Penicillium claviforme is an exceptionally good species for ultraviolet induced mutation experiments. Provides a set of laboratory instructions for teachers and students. Includes a discussion section. (ML)

Presents a laboratory experiment which determines critical temperature and density of carbon dioxide. Discusses critical point and provides equations to estimate liquid volume fraction. Analyzes experimental results in terms of variables. (JM)

A laboratory study is detailed utilizing the skills of hypothesizing, designing experiments, and controlling variables. (EB)

Described is the construction of a density gradient column and several density related experiments which can be performed with the device. (SL)
