Provided are background information, equipment lists, and procedures for four activities for teaching aquatic ecology. Activities include "The Aquatic Food Chain Game"; "Two-Liter Aqua-Vivariums"; "A Sealed World"; and "Weaving a Web: Evaluation." (CW)

Students can study the Arctic by creating Arctic clubs, using modems to communicate with students nationwide who are following International Arctic Project (IAP) explorers. The article describes the IAP, explains how to form a club, and discusses issues that clubs can tackle, for example, pollution, Arctic animals, natural resources, and the…

Describes advances in capture-recapture modeling, including the biologically motivated emphasis on model-based hypothesis testing and the development of models for spatially stratified populations. Discusses the severe problems associated with count statistics reflecting unknown sampling fractions. (67 references) (KR)

Compares present agriculture practices to permaculture farming techniques, presents a historical perspective of permaculture and where these techniques are being successfully practiced around the world. Inserts (vignettes) enumerate the principles of permaculture and the background of Bill Mollison who conceptualized this farming practice. (MCO)

The population of Gyrinus, the whirligig beetle, is assessed using the Lincoln mark-recapture index. This technique has the advantage of helping the student to understand simple proportion as well as other concepts. (Author)

Fifty-three failure-prone students being promoted to first grade were profiled by kindergarten teachers, and incompatibility with subsequently assigned first-grade teachers was determined. Results indicate that teacher-student incompatibility may be related to end-of-first-grade deficits in student reading achievement. (Author/JDD)

Issues related to the ecological assessment of students with mild to moderate disabilities are examined. The paper discusses targeting student behavior according to its context and in relation to present and future socioenvironmental demands; aspects of an ecological assessment model; and thoughts on incorporating aspects of ecological assessment…

Cornell University (New York) plans to use the icy waters of nearby Cayuga Lake to air-condition the campus, but recognizes they can do so only with the community's cooperation. Critics fear the move will change the lake's ecological balance. The university's decision and a subsequent public relations campaign is viewed by some as arrogant. (MSE)

Surveys salient aspects of eastern box-turtle natural history. Explores the societal and ecological factors that have contributed to the decline of the box-turtle population. Contains 18 references. (WRM)

In the relatively new discipline of design education we have the opportunity to frame the way that design education is formulated. The relative lack of theorists in the field of design education studies leaves unquestioned the relevance of conventional practices of design education that are premised on only tangentially relevant Art, Science and…

Reports on a study to compare the energy attitudes of ninth-grade students by gender and by their geographical location. Results indicated that students in Maine had more positive attitudes than those in New Brunswick, that females in both locations had more positive attitudes than males, but that, overall, all had nonpositive attitudes. (TW)

Compares the results of surveys done in 1975 and 1985 with Indiana teachers regarding their physical environment and related problems. Results indicated that teachers had limited environmental literacy but had higher marks in 1985 than in 1975. (TW)

Recounts some of the progress that has been made in the field of population biology. Presents some of the important advances made in the field, along with some of their applications to societal problems. Calls for more cooperation between population scientists and social scientists, and more environmental education for the public. (TW)

Examines some of the traditional and new methods that have been devised to harness energy from the sun in the form of heat. Discusses some current research and developments underway which are lowering the costs of equipment and installation. (TW)

States that tidal power projects are feasible in a relatively limited number of locations around the world. Claims that together they could theoretically produce the energy equivalent to more than one million barrels of oil per year. (TW)
