Traces the history and development of the Deep Sea Drilling Project, focusing on the Glomar Challenger, drilling improvements, and international significance. Includes photographs, illustrations, and tables. (DC)

A variety of methods for producing images and some of the tools available for image analysis are described. (BB)

Describes a "flat" linear air track, glider and spark timer system for use in the physics laboratory. The results of experimental tests using the system are briefly stated. (SA)

Delineated are simple procedures by which evaluations can be performed of the concentrations of contaminants in chemical laboratories. (BB)

Information is given on the basic chemistry of fire and on the characteristics of flammable liquids. (BB)

A heat reclaim system and careful insulating will cut energy use in a University of North Carolina, Chapel Hill, medical laboratory-office building. (Author/MLF)

Tests the hypothesis that, because it uses tri-dimensional sensory pathways which show a higher rate of neural activity than uni- or bi-dimensionals, lab-activity-based instruction is a more effective teaching strategy for learning science than verbal-based instruction. Applies manipulative teaching strategies that use visual, somatosensory, and…

Explains how to maintain biosafety in high school level biotechnology and microbiology courses. Focuses on laboratory skills, biohazard containment, and defense perimeters. (YDS)

Introduces a molecular biology course designed for environmental engineering majors using 16S ribosomal ribonucleic acid-targeted technology that allows students to identify and study microorganisms in bioreactor environments. (Contains 17 references.) (YDS)

Dicusses the effects of using laboratory assistants for disabled students' learning in the chemistry laboratory. Presents two case studies and general strategies for approaching laboratory experiences for disabled students. (KHR)

Discusses small-group apprenticeships (SGAs) as a method for introducing cell culture techniques to high school participants. Teaches cell culture practices and introduces advance imaging techniques to solve various biomedical engineering problems. Clarifies and illuminates the value of small-group laboratory apprenticeships. (Author/KHR)

Presents the script of a skit designed to engage beginning students in a contest to identify and list the most safety violations they observe during the skit. Includes a list of 37 safe laboratory practices. (MKR)

Identifies and defines the student practice of "fudging" which involves faking, fabricating, or stealing data. Identifies factors contributing to and motivations for this behavior in (n=6) high school students. (Author/MKR)

Most schools inadequately protect the health and safety of students involved in science study. Echoing industry standards (and safety records), schools should have safety policies and committees, develop safety orientation programs, make working safely an employment condition, reward good safety performance, inspect and correct, and supply…

Lists 46 household chemicals readily available at local stores by common name, chemical name, chemical formula, and typical commercial source. Suggests that school budgetary constraints can be eased by this practice and that students can become more chemically literate as consumers. (JJK)
