Reviews technical aspects of structure determination in biological electron microscopy (EM). Discusses low dose EM, low temperature microscopy, electron energy loss spectra, determination of mass or molecular weight, and EM of labeled systems. Cites 34 references. (CS)

Described is an advanced biology class project involving study of the effects of organic pollution on an aquatic ecosystem from an sewage treatment plant overflow to evaluate the chemical quality and biological activity of the river water. (DS)

Described is a marine education materials clearinghouse, the Marine Education Materials System (MEMS). MEMS classifies marine education documents and reproduces them on microfiche for distribution. There are 25 distribution centers, each of which has a collection of documents and provides assistance on a request basis to teachers. (Author/DS)

Listed are field stations in the Caribbean and Florida-Bahamas which are suitable for classes in field geology and tropical marine science. Each field station is described by listing the name of the institution, description of accommodations, library facilities, laboratory facilities, boats, classrooms, motor vehicles, study areas, scuba, and…

Described is a marine science course offered to high school biology teachers. The course objectives were designed to introduce teachers to a marine science subject that could be used in the secondary science classroom and laboratory and to create an awareness of the issues surrounding the marine sciences. (DS)

Describes the use of infrared and atomic absorption spectrometry in an introductory chemical oceanography course to introduce students to carbonate mineralogy by having them determine both the crystal structure and the magnesium content of seashells that they have collected. (Author/JN)

Describes an advanced high school course called "Forest Biology" that includes field and laboratory activities, incorporating environmental education into a career-oriented approach. (CS)

Investigates the effectiveness of a structured learning game in overcoming learning difficulties encountered by Israeli students when studying the life cycles of fungi because of lack of structural conceptualization. The Fungi Life Cycle Game (FLCG) was used by undergraduate students enrolled in a phytopathology course. (HM)

In this article, research on nonhuman animals is reviewed to show that there is no discontinuity between humans and other animals. For both, high density is not necessarily harmful. Rather, the effect of high density depends on other factors in the situation. (Author)

The philosophy, purpose, grading procedure, and course requirements for the University of Delaware's "Women in Sports" course are set forth. A course outline is provided, along with tips and a resource materials listing for those interested in initiating similar programs. (LH)

Describes the establishment of the Microbiological Resources Centers (MIRCENS) by the United Nations Environment Program (UNEP) and UNESCO. The goals of the MIRCENS and the role of regional and interregional centers are also described. (HM)

Because workloads frequently do not permit teachers to develop curriculum themselves, their participation in its formative evaluation (field testing) is a productive alternative. A seventh-grade biology program was evaluated by 14 teachers. (CP)

Discusses how the nature of the rock and, particularly, its fossils can be used in ecology courses for schools and colleges to help students to deduce the nature of the environment at the time the rock was deposited. A checklist and ways of identifying geological sites and fossils are included. (HM)

A demonstration is described that encourages students to engage in inquiry in biology. Using chemicals and an overhead projector, the instructor can simulate a living organism projected onto a screen. The reaction can aid students in defining the characteristics of life. (SA)

Reviews the applications of the computer in teaching biology, with special reference to Computer Assisted Learning (CAL) in biology. Examples of available teaching materials are given. Computer Managed Learning is discussed as it relates to the Havering project. (Author/SA)
