Students in a Ohio school project, by using an entire watershed as their laboratory, are exploring ways to ward off pollution. (DS)

Teaching suggestions emphasize dramatic presentations and action programs for maximum student interest and involvement in the environmental crusade. (Author/SD)

Characteristics of the ecological approach to perception are presented. The affordance concept and its relevance is emphasized. Human crowding is discussed in affordance terms. There is a comparison given between present affordance analysis and ecological analysis. (Author/SA)

Presents research findings about mussels, an indicator species for the health of U.S. rivers and streams. Provides mussel descriptions, a history of the decline of mussel populations and cooperative efforts to repair damaged ecosystems cited as the root of the problem. (MCO)

Reports on the Zebra Mussel invasion of North American inland waterways.

With a spotlight upon current agricultural difficulties and environmental dilemmas, this paper considers both the extant and potential applications of genetic engineering with respect to crop production. The nonagricultural factors most likely to sway the impact of this emergent technology upon future crop production are illustrated. (JJK)

Presents a science experiment about oil spills and oil pollution for 7th- and 8th-grade science students. This variation on a method used by pollution control experts to clean up oil spills shows students how oil is collected after an oil spill, explaining that with this method, much of the damage from an oil spill can be averted.
