Presents a plan for a unit of work on spiders. Suggests initiating class discussion with issues of safety and environmental responsibility that are considered when dealing with the hands-on aspects of topics. (KHR)

Describes a press conference that was used as a "teachable moment" when owl pellets being used for instructional purposes were found to be contaminated with Salmonella. The incident highlighted the need for safe handling of owl pellets, having a crisis management plan, and the importance of conveying accurate information to concerned parents.…

Discusses and suggests some solutions for three problems related to chemistry laboratory management, including disappearance of teaching assistants, check in/out procedures, and slow students. (YP)

Describes safety hazards encountered when placing squash balls into liquid nitrogen. Suggests using racquet balls, balloons, or economical Ping-Pong balls. (MVL)

Provides simple recommendation for teachers and school administrators to aid in ensuring safety in the laboratory and reduce risk of injury to students. Discusses legal implications and major areas of concern. (ZWH)

Safe science in schools depends on the premise that students and teachers share similar perceptions on issues of safety related to the general level of a student's maturity. Suggests that a divergence rather than a convergence of perception actually occurs. (DDR)

As a case involving forgotten goggles shows, negligence lawsuits take a damaging toll in terms of money, time, emotion, and self-worth. Educators' best defense is consistently discharging their duties to students in a reasonable, prudent manner. Science teachers should secure all dangerous chemicals, provide adequate supervision, develop proper…

Describes an apparatus that uses liquified gases to wash solids. Discusses the procedures and processes used to do a wash with liquid sulfur dioxide. (CW)

Presents an appendix to the Committee on Professional Training (CPT) of the Division of Chemical Health and Safety of the American Chemical Society. The information is applicable to chemical health and safety policies and practices within the chemistry department of an academic institution. Includes lists of references with safety information. (JN)

Presents a simple, 10-item quiz designed to make students aware that they must learn laboratory safety. The items include questions on acid/base accidents, several types of fire extinguishers, and safety glassses. Answers and some explanations are included. (DH)

Peroxides are unstable, shock-, thermal-, and friction-sensitive compounds whose sensitivity increases with concentration. In addition, peroxides can form in aging organic solvents and stored alkali metals. Cautions related to storage, use, and disposal of peroxides in the secondary school chemistry laboratory are discussed. (JN)

Describes a safety program adopted by Southeastern Louisiana University. Students are given detailed instructions on laboratory safety during the first laboratory period and a test which must be completely correct before they are allowed to return to the laboratory. Test questions, list of safety rules, and a laboratory accident report form are…

Discusses three methods for removing wastes from educational laboratories. These include paying someone with Environmental Protection Agency (EPA) permits, doing part of the work before an EPA contractor carries out final steps, or reducing magnitude of future disposal problems by changing present laboratory procedures. Includes comments on…

Describes a procedure which identifies an experiment as unreasonably hazardous or indicates precautions to be taken rendering the experiment acceptable for assignment to undergraduate students. The procedure follows in parallel form the procedure used to prepare chemical labels. (Author/JN)

Explains the need for methods of increasing students' and administrators' awareness of safety procedures in the chemistry laboratory. Suggests increasing formal courses in safety and cites difficulties inherent in increasing safety courses including the lack of funding and an already overcrowded chemistry curriculum. (DS)
