Discusses issues raised by the English Health and Safety at Work Act, legislation regulating laboratory safety in industry and in schools in Great Britain. (SL)

Explores the Competency Tripod model and flow diagrams as two sources for enabling students' metacognition in a second year undergraduate chemistry laboratory. Results indicate that all four students engaged in metacognitive practices, all believed that flow diagrams are extremely useful, and all understood the Competency Tripod model, but only…

Presents an activity to teach buoyancy. The lab determines what mass of sand can be added to the open end of hollow plastic containers of various shapes so that objects just float at the surface, without sinking, with their entire volume submerged. Discusses Archimedes' principle and aligns with current national science education standards.…

Investigates which factors are important in revising chemistry laboratory experiments to enhance student interest and enjoyment of experimental science. Findings indicate the importance of several factors including varied content, real-world connections, items from outside the student's usual range of experience, well-paced experiments, error-free…

Written in response to the frequent budget overruns experienced by higher education facilities when renovating and expanding laboratories, provides an overview of possible problems and presents a series of procedures and checklists to manage activities associated with such a move or renovation. (EV)

In response to the Texas Hazardous Communication Act (THCA) of 1986 which raised many new health and liability issues regarding students in science laboratories, a laboratory safety survey was generated for use in evaluating laboratory safety. This article contains the easy-to-use survey. (ZWH)

Focuses on three habits associated with personal values and attitudes, and one habit associated with social skills of doing science. Illustrates four habits of mind, first through a story of modern scientific investigation, then as the basis of school laboratory science experience. Discusses implications related to integration of these four habits…

Introduces a laboratory activity designed for an undergraduate developmental biology course. Uses Play-Doh (plastic modeling clay) to build a multicellular embryo in order to provide a 3-D demonstration of cleavage. Includes notes for the instructor and student directions. (YDS)

Defines dichotomous keys as common learning tools based on identification rather than memorization. Provides an example of a dichotomous key developed for introducing histology in human anatomy and physiology (A&P) courses and explains how students can use the dichotomous key. Discusses the goals of the exercises and the process of…

Presents a creative set-up that allows students with latex allergies full participation in chemistry labs. Discusses how one student having a latex allergy is turned into a learning experience for all and how this challenged lab safety. (ASK)

Introduces a series of molecular genetics laboratories where students pick a single colony from a Drosophila melanogester embryo cDNA library and purify the plasmid, then analyze the insert through restriction digests and gel electrophoresis. (Author/YDS)

Presents the results of a wide-ranging survey of science technicians in schools and colleges that sought the views of heads of science via a telephone survey. Examines comments regarding technicians and the existing technician job structures. (Author/YDS)

Discusses design and architectural features of two new science facilities at the Florida Institute of Technology in Melbourne, Florida, and a new graduate research tower the University of Wisconsin at Madison. Notes the important convenience associated with interior windows in these facilities, which allow researchers, faculty, and students to see…

Examines motivational methods among undergraduate chemistry students and identifies differences between methods of persuading students to prepare for laboratories. Methods include quizzes, scheduled presentations, unscheduled presentations, and a control method. (YDS)

Uses concept-based laboratory reports to incorporate technical writing into teaching. Features three paragraphs in the writing format: introductory paragraph, data paragraph, and conclusion. Recommends using this teaching method, especially in chemistry laboratories, because of the difficulties students have in understanding. (YDS)
