Feedback from assessments should be the foundation for improvements students make in their lab work. Therefore, in this study, a standard rubric that reflected the scientific method was employed as an intervention to assess student lab write-ups. Students preformed three labs all based on consumer research. The first lab was completed without the…

This selected collection of How-To-Do-It articles published in the American Biology Teacher during the past six years presents experiments that can be conducted safely under properly trained and responsible teacher supervision. Contents include: (1) "General Biology and the Nature of Science"; (2) "Cells and Molecules"; (3) "Microbes and Fungi";…

This handbook was prepared to help science teachers, administrators, and other school staff members understand and avoid situations in which accidents might occur in the science laboratory, on field trips, or during outdoor education experiences. Suggestions contained in this publication are generally agreed upon and recommended for consideration…

This bulletin responds to frequent requests for practical information relating to equipment and supplies for teaching science in small high schools. Laboratories for science courses have been for several decades necessary parts of every high school teaching the sciences. This bulletin is a brief survey of the necessary equipment to teach the…

Features of a biology demonstration laboratory designed to handle large number of students and provide opportunities for using materials including live specimens for practical work are described. The design of the demonstration laboratory is given. (PS)

Educators seeking support for continuation of science laboratory instruction can find information in the ERIC data base. Sections cover: (1) what's available; (2) beliefs about the role of laboratories; (3) what critics say; and (4) research evidence. (MP)

This article presents a discussion of the HMI's National Secondary Survey in England during 1975-1978, emphasizing the status of science in the last two years of compulsory education. (SA)

Presents a description of the National Center for Atmospheric Research, a center where scientists pursue research interests, where research facilities, too large and expensive for any one institution to maintain, are housed, and where unified planning for research is made in response to national and international concerns. (SA)

The use of computers as laboratory instruments is viewed as overlooked. Numerous applications developed for a simple, single-board microcomputer by a group of Technical Education Resource Centers (TERC) are noted. The trend toward decreasing costs of lab interfacing is expected to continue into the future. (MP)

Presents a review of currently available technology of new trends in liquid chromatography-mass spectrometry. (BB)

Described is a demonstration utilized to measure the heat of vaporization using the Clausius-Clapeyron equation. Explained is that when measurement is made as part of a demonstration, it raises student's consciousness that chemistry is experimentally based. (Author/DS)

The National Research Council has published a comprehensive report on procedures for handling hazardous chemicals and on other aspects of laboratory safety. By early 1981, the Occupational Safety and Health Administration intends to present preliminary proposals for safety in chemical research laboratories. (WB)

Provides information regarding spill control systems in chemical and biological laboratories. Various methods currently in use are described. Suggestions are made for the use of absorbents. (CS)

Discusses problems of handling, storage, and disposal of chemicals in Australian secondary school science laboratories, and suggests ways of reducing the potential hazards which exist. (HM)
