Points out that research is an inefficient endeavor as it relates to time, but the rewards can be gratifying and of value. Reports on a compilation of faculty and administration observations, alumni and student surveys, and some readings on the topic. (RT)

Introduces an interdisciplinary activity using a cola drink. Describes the lesson plan, including objectives, procedures, evaluation, projects, and conclusions. Provides two laboratory sheets containing problem, hypothesis, materials, procedure, observations, and conclusions, vocabulary table, and data table. (YP)

Reviews research on the purpose and effectiveness of laboratory activities. Discusses epistemology, problem solving, cooperative learning, student involvement, assessment, and teachers as researchers. (YP)

Describes apparatus for Doppler demonstrations. Provides several pictures of the apparatus and ways it could be used. (YP)

Discusses the equipment and techniques for taking photographs using a sound-actuated trigger. Describes a method using two flash units, two sound triggers, and a high-frequency clock to measure speeds. Provides several high-speed photographs. Lists 11 references. (YP)

Discusses a high school advanced placement physics course cooperating with neighboring college. Describes the background, titles of experiments, report format, and discussion. (YP)

Hampshire College needed to create opportunities for advanced undergraduates to have extensive laboratory or field experience in experimental sciences. A general biochemistry course, taught almost entirely in the laboratory, is described. The focus of the course is enzymes as catalysts and as proteins. (MLW)

Presents the construction aspects of a simple but reliable colorimeter made from locally available components. Notes the absorption range to be 400-750-nm. Lists seven experiments done on the instrument. (MVL)

Discusses the flotation method for the determination of the density of solids. Provides the stepwise experimental procedure with typical data tables and graphs. (YP)

Describes a course entitled "Biotechnology Laboratory" which introduces a variety of laboratory methods associated with biotechnology. Describes the history, content, and seven experiments of the course. The seven experiments are selected from microbiology and molecular biology, kinetics and fermentation, and downstream…

Capitalizing on the research skills of the faculty, the introductory chemistry course at the College of the Holy Cross (Massachusetts) invites students to participate in the processes of speculation, investigation, and discovery, using a laboratory-based curriculum that emphasizes the scientific method. (Author/MSE)

Describes a simple, safe, and inexpensive hands-on demonstration of normal and abnormal coagulation using bovine blood plasma. (JRH)

Describes new software called "PopGenetics" that is useful for conducting hands-on laboratory activities that illustrate population genetics. Users investigate the effects of selection and random drift on changes in allelic frequencies, the effect of mutation, and interactions among these three parameters. Designed for use on Macintosh…

Investigated the problems chemistry majors have with learning distillation concepts in traditional chemistry laboratory courses. Reports that students take the generalized concepts at face value, construct decontextualized concepts for distillation, and cannot interpret their observations or make reasoned decisions based on the theoretical…

An activity that uses dandelions to show the phenomenon of geotropism is described. The process of sedimentation, which causes the bending, is observed at moderate magnification under a standard microscope. A list of needed materials, directions for the tissue dissection, and time-lapse photographs of the process are included. (KR)
