Experiences, group dynamics, hazards curriculum, and logistics of a canoe trip of the Mississippi River are discussed. (RE)

The environmental awareness of village and rural children in Ghana differed from that of urban children. This study explores the knowledge of some Ghanaian children about water and full resources and their relationship to local development issues. (Author/RE)

Techniques for effective photography of aquatic organisms in the field and laboratory are described. Photography of microscopic organisms and construction techniques of photoaquaria are described. (CS)

Presents generalizations regarding how running water systems change physically, chemically and biologically with stream order, i. e., from the tiny headwater streams (order 1) to those receiving first order headwater tributaries (order 2) and so on. Food chain diagrams respective of stream order are explained. Stream study projects are suggested.…

Presents discussions on sources, health impacts, methods of analysis as well as lengthy discussions of lead, nitrates, and atrazine as related to water pollution and the interdisciplinary nature of the modern chemistry curriculum. (DKM)

Reports on a school project that focuses on a lake's ecosystem and engages students in data collection and analysis. Data are shared with the local government to assist with the monitoring of water quality. Includes tips on group cooperation and assessment. (DDR)

Describes a physics experiment investigating temperature prediction and the relationship between the physical properties of heat units, melting, dissolving, states of matter, and energy loss. Details the experimental setup, which requires hot and cold water, a thermometer, and ice. Notes that the experiment employs a deliberate counter-intuitive…

Discusses the problem of symmetry avoidance using water as an historical example. Uses simple pi systems for the analysis. Provides methodology and examples. Investigates two naive arguments. (MVL)

Describes a three-month environmental preservation training program administered by the Japan International Cooperation Agency focused specifically on Brazil. (MDH)

Describes a doctoral student's experiences on a trip to Turkey. Discusses the Southeast Anatolia Project involving dam building on the headwaters of the Euphrates to provide electricity and irrigation. Suggests the experience as an example demonstration of complexities of human and environmental interaction and other themes of geography. (DK)

A study assesses Wyoming elementary educators' (n=450) knowledge of water topics and the priority given to these topics in their curricula. Results indicate educators perceived they had inadequate knowledge of water topics and failed to give these topics priority in curricula. The need for development of elementary curriculum and workshops with…

Included are three demonstrations that include the phase change of ice when under pressure, viscoelasticity and colloid systems, and flame tests for metal ions. The materials, procedures, probable results, and applications to real life situations are included. (KR)
