Discusses the use of the System Dynamics technique in simulating a chemical reaction for kinetic analysis. Also discusses the use of simulation modelling in biology, ecology, and the social sciences, where experimentation may be impractical or impossible. (MLH)

Israeli tenth-grade students completed a chemistry laboratory course by either performing the experiments or by viewing films of the experiments. Among the results of an attitude test given to both groups was that students find personalized laboratory more effective than films in promoting their interest in chemistry. (MLH)

Discusses an undergraduate course which includes lectures, laboratory, and field trips and is designed for the interim winter semester. The course is interdisciplinary, involving a study of the biochemistry, pharmacology, and physiological significance of compounds from marine flora and fauna. (MLH)

Describes an interview-type study of 15-year-old chemistry students that revealed a poor understanding of the mole concept, and discusses the major features of their misunderstandings. (MLH)

Presented are two science demonstration projects: (1) the simulation of a magnetic survey utilizing a bar magnet buried in a sand box and (2) an investigation of the reaction between lead nitrate and sodium hydroxide. (SL)

Describes a general chemistry course taught by the Keller Plan, or personalized system of instruction, at a university with a large minority enrollment. Evaluation shows that students feel that they are learning more and getting higher grades. (MLH)

Described is a kit of 16 commonly available basic elements and several activities and experiments that can be conducted to investigate the properties of the various elements. (SL)

In the applications of instrumental analysis lessons, advanced instruments with the needed experiments are needed. During the lessons it is a fact that the more experiments are performed, the more learning will be. For this reason, experiments that do not last long and should be performed with more simple instruments and that increase students"…

The Open Distance Learning (ODL) concept is fast becoming popular all over the world and it has a lot of relevance for a highly populated country like India. However, the most important aspect of this type of teaching-learning process is establishment of the credibility especially when the laboratory based science programmes are delivered from…

One of the major challenges facing people committed to Teaching Safety in High Schools, Colleges, and Universities is keeping up with both the wide range of relevant technical information about potential hazards (ranging from fire protection to chemical hazards to biological issues) and the ever-changing world of safety regulations and standards.…

This booklet presents some activities on chromatography. Directions for preparing leaf pigment extracts using alcohol are given, and paper chromatography and thin-layer chromatography are described as modifications of the basic principles of chromatography. (KHR)

This short article consists of some thoughts derived from a longer paper (Palmer, 1992), together with some more recent ideas. I became interested in buckminsterfullerene (Buckyballs) as a result of an E-Mail discussion of the topic in 1991. The chemistry of buckyballs is now evolving very rapidly and is gradually creeping into school…

This teacher's guide is designed to provide science teachers with the necessary guidance and suggestions for teaching nuclear chemistry. In this book, the fundamental concepts of nuclear science and the applications of nuclear energy are discussed. The material in this book can be integrated with the other modules in a sequence that helps students…

This teacher's guide is designed to provide science teachers with the necessary guidance and suggestions for teaching about energy and the environment. In this book, energy is discussed as one aspect of a general problem in environmental chemistry. The material in this book can be integrated with the other modules in a sequence that helps students…

Using interesting interactive educational tasks increases student motivation in difficult subjects such as biology, physics, and chemistry and creates more effective science instruction. This paper presents a method for developing interactive educational tasks that make science subjects easy to understand. (Contains 10 references.) (YDS)
