Explains that mercury is a dangerous substance to use in school science laboratories and gives several examples of mercury poisoning. Lists some precautions that should be taken in case of mercury spillage in the lab. Advocates using non-mercury laboratory equipment and limiting student access to mercury to prevent dangerous situations. (YDS)

Discusses whether it is biologically plausible for an environmental laboratory contaminant to cause fibromyalgia. Presents a study of two populations which indicated that fibromyalgia was occurring at an elevated rate in a building where ventilation was deemed inadequate for laboratory activities. (Author/WRM)

Reports on an ethnographic study of a molecular biology research laboratory called Sally's Lab. Portrays the social and cultural construction of a scientific community by studying the daily practices of the lab members and interpreting these observations. Concludes that there is not one set of experiences that pertain to all members within a given…

Points out the difficulties of teaching evolution and recommends using simulations to circumvent these problems. Uses artificial organisms called caminalcules for teaching which allows students to focus on principles without preconceived ideas. (Contains 16 references.) (YDS)

Discusses revisions in general chemistry laboratory to include group project work. Describes evaluation techniques and sample projects. (MKR)

Discusses the viability of cognitive apprenticeship for learning science in relation to findings from an investigation of a research project involving high school students working in a university chemical engineering laboratory under the mentorship of a university-based scientist. Reports that students were empowered to seek empirically viable…

Explores associations between students' (n=1,592) perceptions of their chemistry laboratory classroom environment and their attitudes towards chemistry. Findings indicate significant associations between the nature of the chemistry laboratory classroom environment and the students' attitudinal outcome. "Integration" and "rule…

Presents the results of a study analyzing students' gestures and scientific discourse by supporting three assertions about the relationship between laboratory experiences, gestures, and scientific discourse. Discusses the implications for laboratory experiments which students should attempt to explain while still in the lab rather than afterwards…

Modifies an extended lab activity from a cookbook approach for determining the percent mass of water in copper sulfate pentahydrate crystals to one which incorporates students' prior knowledge, engenders active mental struggling with prior knowledge and new experiences, and encourages metacognition. (Contains 12 references.) (ASK)

Develops and modifies a series of 11 lab activities designed to strengthen and build science laboratory and inquiry skills for students in physical science classes. Includes a figure that summarizes the sequencing skills and concepts developed by these lab activities. (ASK)

Points out the importance of the ability to apply knowledge in a problem-solving manner to real-life situations for biology students rather than possessing an exhaustive accumulation of facts. Describes a teaching approach that employs three-dimensional animal models to teach the student how to use deductive reasoning and critical analysis to…

Explores how to create an optimal learning environment in all curriculum areas, particularly with old science labs. Discusses how educators are offering course material online and using technology to more efficiently deliver lectures and presentations and to create more computer-generated lab demonstrations. (GR)

Explores the after-effects on college laboratories of the anthrax mail scare; scientists say the anthrax scare justifies tougher rules on biological agents, but some fear that Congress may go too far. (EV)

The notion of problem-based physics laboratories enhanced by computer technology has been coined "studio physics" (Wilson, 1994) and has been practised at various institutions for some time (Cummings, Marx, Thornton, & Kuhl, 1999; Williams, MacLatchy, Backman, & Retson, 1997). In recent years, new technology tools have been available to supplement…

Chemistry should be fun and exciting, but much preparation and skill are needed by the teacher and students in working with chemicals. Unfortunately, accidents do happen and things can blow up, but these incidents can help be prevented by knowing and following proper safety procedures. Knowing which chemicals are appropriate for the middle level…
