Notes that this experiment takes safety and noncarcinogenic reactants into account. Demonstrates the use of diazonium salts for the replacement of an aromatic amine group by a phenolic hydroxyl. Involves two pleasant-smelling organic compounds, methyl anthranilate (grape) and methyl salicylate (oil of wintergreen). (MVL)

Suggests the use of small canopy hoods that provide flexibility of vertical and horizontal adjustment over the lab bench as a replacement for permanent hoods. Includes many safety related instances where canopy hoods should be used. (MVL)

Safety hazards that are frequently found in science classrooms are addressed in this digest which updates and supplements the 1980 ERIC/SMEAC information bulletin "Safety in the Science Classroom." Information obtained from journal articles and safety guides is presented in the categories of: (1) risks involved in science activities; (2)…

This book is designed to develop sequentially a range of concepts and skills relevant to the basic disciplines of science. Emphasis has been given to the knowledge basis of science, the social context of science, design and technology, and knowledge and skills relevant to personal development. Students are provided an opportunity to engage in…

This paper on science instruction for learners with mental disabilities reviews the limited literature base in the field and provides practical information on teaching science in special settings. To assist in implementing best instructional practices in science education, the paper discusses the curricular make-up of science instruction; various…

This pamphlet offers suggestions for improving laboratory safety. It is based on the notion that having an understanding of inherent hazards and learning how to be safe should be an integral and important part of science education. It is organized into "steps requiring minimal expense" and "steps requiring moderate expense." Included in these…

Discusses indoor air pollution in general and formaldehyde in particular, citing major sources of formaldehyde in home building materials and home furnishings. Also describes a laboratory procedure necessary to test for formaldehyde levels in the air and in materials. Includes list of equipment required. (JM)

The use of live animals in the secondary school laboratory is discussed along with suggestions for increasing the use of live animals and challenges to those teachers who restrict this use. (SA)

Described is a plan used in Iowa to remove stockpiled, unwanted chemicals from storeroom shelves. Points out that the plan takes 12-15 months to complete. Notes the average cost per district was $575. (MVL)

Estimates that about 30,000 universities, colleges, and high schools produce a total of 4000 metric tons of hazardous waste annually. Discusses the difficulties that academic institutions have in disposing of small amounts of waste. Lists college courses with the potentially hazardous wastes usually produced. (MVL)

With thousands of activities available, how does a teacher select activities appropriate for the classroom? Describes the guidelines of the "Science Activity Filter," which provide a useful protocol for evaluating science activities for their value in the classroom, allowing the teacher to use resources effectively, minimize discipline and safety…

Presents the following guidelines to consider before, during, and after hands-on inquiry: (1) plan and prepare; (2) create problem intrigue; (3) give students the responsibility of solving the problem; (4) offer feedback and guidance; (5) debrief; and (6) anticipate, prevent, monitor, and adapt. (PR)

This paper presents a viewpoint on educator responsibilities toward helping youth develop the skills necessary to cope with life as well as consideration on how to present science in a safe environment. Discussions include safety in the learning environment, litigation, effective teaching, effective schools, the goals of science, and the mandate…

This document was prepared in an effort to help science teachers, administrators, and school staff members in California understand and avoid situations in which accidents could occur in the science laboratory or on field trips and outdoor education experiences. It contains major sections on: (1) first aid (including information on animal and…

Describes an experiment involving pineapples and gelatin that allows students to investigate the conditions that typically render an enzyme functionless, similar to the effect of nerve gasses. Discusses the materials, procedures, and results, drawing analogies to the effects of a nerve gas. (CW)
