Describes some of the ancient geologic history of the Florida Keys from Key Largo to Key West including the effects of glaciers, sea level rise, reef distribution, spurs and grooves, backstepping and ecological zonation, growth rates and erosion. Predicts future changes in this area. (CW)

Traces the development of the civil engineering code of ethics. Points out that the code does have an enforceable provision that addresses the engineer's responsibility toward the environment. Suggests revisions to the code to accommodate the environmental impacts of civil engineering. (TW)

Precycling, or purchasing wisely to reduce waste, is the EPA-preferred way to conserve resources and extend landfill life. A three-month campaign using radio, television, and in-store advertising was effective in teaching this concept in the greater Salt Lake City area. (Author/AIM)

A 21-item scale combining and modifying an environmental paradigm and a social paradigm was used in 2 surveys. This paper compares attitudinal dimensions resulting from factor analysis. Similarities in terms of relationships between scores on the scale and preferences for energy-related options were also assessed. (Author/CW)

Provides answers to questions regarding the ozone problem: (1) nature of ozone in the troposphere and stratosphere; (2) possibility of sending the excess ozone at ground level to the stratosphere; (3) possibility of producing pure ozone and carrying it to the stratosphere; and (4) banning chlorofluorocarbons. (YP)

Attempts to develop a theoretical foundation for the practice of ecological education. Focuses upon the severed relationship between man and nature. Identifies seven elements of ecological education designed to develop ecological action and experience as well as knowledge. Argues that, without a comprehensive, ecological framework, environmental…

Describes changes to a traditional study of population in yeast colonies. Changes to the procedures include: (1) only one culture per student team; (2) cultures are inoculated only once; and (3) the same tube is sampled daily. (DDR)

Discusses practical work which can be completed in a few hours that enables students to explore the genetics of the dandelion plant, which reproduces asexually. Dandelions, measuring instruments, and student imagination are needed for this activity. (DDR)

Presents aspects of current thinking about the environment within the international community. Discusses an inquiry into practice among secondary science teachers (N=81) in England. Contains 38 references. (DDR)

Explores the prevalence of ideas among 16 to 19 year-old students about the application of the rapidly expanding technology of genetic engineering to food production. Findings suggest that more females were cautious about these foodstuffs than were males. Contains 20 references. (DDR)

Describes an activity in which students try to assess the problematics of modifying brackish saline water to grow high-quality crops. Students grow seedlings in solution culture over a two-week period to learn about the effects of salts, ions, and essential plant nutrients. (WRM)

Explains that Michael Sanera's analysis of what is wrong with environmental education raises disturbing questions about his appeal for scientific accuracy and balance. Argues that the critique itself must be able to meet tests of rigor. (DDR)

Investigates the way in which students apply the ecological concept of interdependence of species to the issue of preservation of species. Interviews with 12-year-old children (N=63) and 16-year-old children (N=60) provide the data for this study. Contains 27 references. (DDR)

Shares insights on community/environment-based learning gleaned from teachers over 30 years. Delineates what the author has identified as stages that teachers experience as they begin to move outside their classrooms. Genuine support for this approach would hasten its adoption. (DDR)

Distinguishes between natural resource programs and natural resource projects and provides a project planning outline. Addresses critical elements and concerns in the development of natural resource programs. (DDR)
