Current scientific and technologiical issues should be incorporated into more active classroom, laboratory, and extracurricular learning so that students can perceive the future as personally relevant. (MJL)

Summarizes common practices designed to promote safety consciousness in high school chemistry laboratories. (CS)

Describes ways to modify teaching aids and laboratory materials for the visually handicapped student in an introductory college chemistry course. (CS)

Supplies short descriptions of several computer applications in the college science classroom and laboratory, including: applications; interfacing and data collection with the TRS-80; programs for activity corrections in acid/base and precipitation titration curve calculations; computer-assisted data analysis of enzyme kinetics; and microcomputer…

Reviews the dangers of benzene as a toxin as well as a flammable substance. (CS)

Reviews the development of accelerators over the past 50 years. Topics include: types of accelerators, including cyclotrons; sociology of accelerators (motivation, financing, construction, and use); impact of war; national laboratories; funding; applications; future projects; foreign projects; and international collaborations. (JN)

This report reviews some goals for laboratory activities in contemporary science teaching, discusses an investigation that analyzed and compared laboratory activities from two major physics guides, and discusses the implications of the goals and analysis for physics teaching. Six major deficiencies in the two laboratory handbooks are identified.…

Discusses the need for ships enabling researchers to work in rough weather, thus expanding research capabilities; suggests a prototype semisubmerged ship which would meet research requirements. (DC)

Presents position statements indicating the necessity of laboratory experiences for the teaching and learning of science in the elementary school. Three different perspectives are addressed: research, curriculum, and teaching. (DS)

Suggests that cyclohexane be used as a solvent in experiments usually using benzene, which has been placed on the list of chemicals that are confirmed carcinogens. Reasons for selection of cyclohexane and experimental procedures using this solvent are described. (CS)

Described is a sensible and positive attitude toward waste that can both aid the safe, smooth running of a teaching laboratory and also be an important learning tool. (Author/DS)

Described is a nontraditional approach to the evaluation of laboratory instruction in general physics courses which focuses on the identification of telling questions, key concepts and basic phenomena involved in the experiment, description of the method used, and the results. (DS)

A procedure is described for providing preparations of dividing cells from root apical meristems, requiring only inexpensive equipment and minimal experimental skill, and using 8-Hydroxyquinoline and Toluidene-blue as a chromosome stain. The method has been sucessfully tested in schools and yields permanent preparations of adequate quality for…

The uses of isoenzyme assays are reviewed as they relate to solutions of practical problems. Emphasizes their use of diagnostic tools in medicine, specifically in cardiac profiling. Suggests that principles of isoenzyme assays readily demonstrate molecular structure, acid-base equilibria, kinetics, and electrochemistry to general chemistry…

The application of chemistry to the justice system is presented. The role of the forensic chemist, historical development of forensic laboratories, and tools of the criminalists are also discussed. (HM)
