A technique is presented which utilizes wax moth larvae in a laboratory investigation of an insect virus. Describes how an insect virus can be used to introduce undergraduate biology students to laboratory work on viruses and several virological concepts. (SA)

Describes a rapid staining technique for investigating the anatomical expression of two recessive genes. The demonstration is intended to stimulate students who are interested in the practical applications of genetics. (Author/SA)

Basic marine aquaria equipment, techniques for maintenance, specimens and food for the marine organisms are discussed. Several sources of specimens are included. (SA)

The future of the academic oceanographic fleet is discussed. The focus of the controversy surrounding the ships appears to be their size and fuel efficiency. Budget constraints and various ways in which to schedule ships for researchers are the primary concerns. (SA)

Describes a lysozyme assay for use in the biology classroom to teach enzymology. Provides background information, materials and methods, sources of lysozyme, and evaluation of the assay. (DS)

Materials and methods for studying the functioning and responses of stomatal guard cells are described. (PB)

Determined was the effect of autotutorial instruction in the laboratory portion of a general biology course designed for nonbiology majors. Results indicate positive effects in enrollment, increased retention, and improved student achievement. (CS)

These learning stations use questions about television and film stars, as well as famous historical figures, to motivate students in problem solving and other technical language skills. (Author/SJL)

The ideal learning center is, in essence, a living definition of competency-based education. Such a center has the capability of meeting the diverse needs of adult school students while at the same time raising the coping skills or competencies of its participants on an individualized basis. (Author)

Describes kinetics experiments completed in a single two-hour laboratory period at 25 degrees Centigrade of nitrito to nitro rearrangement, based on the recently discovered base-catalysis path. Includes information on synthesis and characterization of linkage isomers, spectrophotometric techniques, and experimental procedures. (SK)

Decline in research emphasis in universities is tied to a number of factors: defensive apathy in the university scientific community; weakening links between teaching and research; declining enrollments; problems in interdisciplinary work; employment stability and aging faculty, obsolete equipment, support staff reduction, and growing bureaucracy.…

Presents a simple, economical model of circulatory behavior that illustrates the effect of changes in cardiac output, peripheral resistance and compliance on arterial blood pressure. (CS)

Discusses the two-capacitor problem by considering the self-inductance of the circuit used and by determining how well the usual series RC circuit approximates the two-capacitor problem when realistic values of L, C, and R are chosen. (GA)

For this 12-hour laboratory project students examine a model and explain why equipment is placed where it is, and then install some piping on the model. (BB)

Describes a laboratory activity which can be done with equipment normally available for introductory college courses. It measures the ratio of the radioactivity per unit mass of a unicellular alga to the radioactivity per unit mass of the medium in which it grows. (HM)
