Describes how a Polaroid camera can be modified for spectroscopic experiments. Reviews experimental procedures and discusses results that students can obtain within one normal laboratory period. Suggests additional experiments for investigating emission from other sources. (ML)

Proposes a series of experiments that integrate analytical techniques in order that students are able to compare, based on their laboratory results, the relative reliabilities of the most common therapeutic drug monitoring methods. Discusses materials, procedures, and results of three experiments on the determination of drug concentration by…

Discusses the role of the fruit fly in genetics research requiring a multidisciplinary approach. Describes embryological and genetic methods used in the experimental analysis of this organism. Outlines the use of Drosophila in the study of the development and function of the nervous system. (RT)

Describes three methods and their advantages and disadvantages for introducing genes into animals. Discusses the predictability and tissue-specificity of the injected genes. Outlines the applications of transgenic technology for studying gene expression, the early stages of mammalian development, mutations, and the molecular nature of chromosomes.…

Explanation of the purpose of microcomputer simulations in history classes at the college or secondary school level focuses on the development of one simulation, The American Revolution. Highlights include effects on learning processes of using simulations in a microcomputer laboratory; student evaluations of the simulation; and creation of the…

Describes eight experiments involving the use of common consumer products that could be incorporated into quantitative and instrumental analysis laboratories. Discusses these activities in terms of illustration of principles, awareness, and critical thinking. (CW)

Discusses the incorporation of environmental chemistry topics into the traditional high school chemistry curriculum. Describes and provides lesson plans for the sulfur cycle and acid rain, and radioactivity and nuclear energy. Considers possible laboratory experiments. (CW)

Analysis of responses of gifted students (N=220) at a university laboratory high school to a questionnaire about the school library indicated that students frequently used the library for informational and recreational materials; were generally satisfied with library materials; and were avid readers tending to view less television than nongifted…

Describes results of survey of media service directors at public universities in Ohio to determine the expected longevity of audiovisual equipment. Use of the Delphi technique for estimates is explained, results are compared with an earlier survey done in 1977, and use of spreadsheet software to calculate depreciation is discussed. (LRW)

Presents several strategies to teach the reactivity of metal elements. Stresses the safety aspects of these demonstrations using an overhead projector and a plexiglass safety shield. Lists some of the essential learnings desired in these activities. Includes a chart of the activity series of metals. (CW)

Describes a classroom experiment designed to teach students the fundamentals underlying the normal coordinate analysis procedure of a polyatomic molecule. Uses a reverse procedure from traditional experiments of this type by providing the values for the force field and working backwards. (TW)

Abstracts of seven selected papers from the 7th Annual Microcomputers in Education Conference are presented. Papers are included on microcomputer-based labs, teaching science with robots, microcomputer software, problem solving, computer integrated math activities, and computer assisted mathematics. (RH)

Describes the use of language lab materials supplied by the pedagogical journal "Russkij Jazyk Za Rubezom" in an advanced Russian-language class. Each week students were given a relevant picture and vocabulary list prior to listening to a taped story. The story was used as the basis for conversation. (LMO)
