Discusses forces that shape the behavior of water as a drop meanders down a windowpane. A homemade apparatus for studying meanders is described along with several experiments. Contact angles, molecule attraction, surface area, air tension, and gravity drag forces are some of the topics addressed. (DH)

Cartilage is a fundamental biological material that helps to shape the body and then helps to support it. Its fundamental properties of strength and resilience are explained in terms of the tissue's molecular structure. (JN)

The tendency of a poured liquid to cling to the outside of a container is known as the "teapot effect." The nature of the teapot effect and experiments investigating this phenomenon are described. (JN)

The purpose of this study was to research the purported effects of reduction of "mind set" and achievement of greater consistency in data classification when using Simon's Problem-Solving Approach. (Author/JC)

This paper highlights two strategies to include students and teachers as partners in the co-design of the enacted curriculum. During the development cycle, the design team developed sixteen lessons that included inquiry opportunities, small group conversations, and multiple perspectives around complex issues. The lessons were implemented during…

The Water in Africa Project was realized over a 2-year period by a team of Peace Corps volunteers, World Wise Schools (WWS) classroom teachers, and WWS staff members. As part of an expanded, detailed design, resources were collected from over 90 volunteers serving in African countries, photos and stories were prepared, and standards-based learning…

Technology has a unique place in the elementary classroom. It provides an unparalleled vehicle for integrating many traditional subject areas. It serves to break down curricular barriers while at the same time promoting situated learning. This paper describes the implementation of a unit that focuses on the technology of the dike systems. Dikes…

Considering that, of the 250 million new cases of water-associated diseases reported every year, 75% occur in tropical, poor, rural areas and slum-outskirts of big cities, it becomes clear that water education is a priority. This booklet illustrates that early water education can benefit the entire community. Since habits related to water use are…

Describes the principle involved in an osmotic pump used to extract fresh water from the oceans and in an osmotic power plant used to generate electricity. Although shown to be thermodynamically feasible, the osmotic principle is not likely to be used commerically for these purposes in the near future. (JR)

Michiganders by the thousands proved ready to spend part of their on developing a statewide environmental education program. (Editor)

Discusses the phsico-chemical principles underlying fish gas bubble disease and the methods of treating supersaturated water. (CC)

Headquartered at Joliet, Illinois, the Army Ammunition Procurement and Supply Agency aims to mechanize and clean up its manufacturing facilities. Six go-co (government owned - contractor operated) plants involved in the modernization program are described. (BL)
