A multidimensional pharmacodynamic screening experiment that addresses drug interaction is included in the pharmacology-toxicology laboratory experience of pharmacy students at the University of the Pacific. The student handout with directions for the procedure is reproduced, drug compounds tested are listed, and laboratory evaluation results are…

Outlines an approach for instruction in a physical chemistry laboratory which combines traditional and project-like experiments. An outline of laboratory experiments and examples of project-like experiments are included. (BT)

An experiment is presented on the formulation of a negative photoresist. It is intended for use as a fifteen minute classroom demonstration for undergraduate general chemistry students. (SA)

The author describes activities he uses with secondary school science students to learn about their reasoning. (Author/SA)

Describes an experiment, designed for and tested in an advanced inorganic laboratory methods course for college seniors and graduate students, that prepares and analyzes several samples in the nearly ideal potassium perchlorate-permanganate solid solution series. The results are accounted for by a theoretical treatment based upon aqueous…

Describes an experiment that, using a commercially available solid-state selective electrode in conjunction with a pH-meter, determines the stability constants of sodium sulfate while varying the ionic strength of the media using sodium chloride. Detailed reproducible procedures of both the measurements and calculations are described. (BT)

An inexpensive apparatus for demonstrating low temperature mineral synthesis in an undergraduate geology laboratory is described. (Author/SA)

Recommendations are given for obtaining high quality preparations of chromosomes with relatively little equipment using an improved Feulgen-squash technique. (Authors/SA)

Presents a method for microscopically examining cytoplasmic streaming in root cells, and physiologically examining the delivery of ions to the xylem exudate. The expected result does not occur and the authors believe that students learn to re-examine the assumptions, thereby increasing their skills in scientific inquiry. (Authors/SA)

This paper, presented at the conference on the role of the laboratory in physics education which was held in Oxford, England in July 1978, describes the role of the laboratory in school and university physics in Eastern Europe. (HM)

Describes a short course for parents and children in grades 5-8. Fundamental concepts of chemistry are the focus of the experiments described. (SA)

Presents some introductory experiments involving the reaction between EDTA and several metal ions using metallochromic indicators. The experiments represent familiar reactions and are followed by suggestions for extension into areas of discovery work by students. (Author/SA)

Discusses how laboratory activities can match science teaching goals. Analysis of two commonly used laboratory investigations in high school physics and biology are presented using a list of 24 skills and behaviors which are related to the processes of scientific inquiry and problem solving. (HM)

Describes a simulation done by students in a Year 4 undergraduate physics laboratory course on pulse technology. The course objective was to provide students with experience in computation pulsed electrical circuits and in comparing the computation with experiments. Results showed that the microcomputer simulated experiments made for a more…

Errors found in a common physics experiment to measure acceleration resulting from gravity using a linear air track are investigated. Glider position at release and initial velocity are shown to be sources of systematic error. (CW)
