Presented are activities which provide a program of first-hand experiences in field ecology for groups of three to five students under the leadership of a teacher or adult volunteer. Concentration is centered upon study of the effects of environment on living plants and animals and the interdependence of members of ecosystems. Each investigation…

In response to the need of many individuals and communities throughout Pennsylvania for an effective network to disseminate information about water resources, a study was conducted to explore possible relationships between the Water Resources Center and the Pennsylvania Cooperative Extension Service. The report focused on a case history review of…

Provides some background information on acid deposition. Includes a historical perspective, describes some effects of acid precipitation, and discusses acid rain in the United Kingdom. Contains several experiments that deal with the effects of acid rain on water quality and soil. (TW)

Discusses the problems created when wetlands are drained or altered by humans. Provides a brief case study of the Everglades as an example of the effects of human intervention. Presents four learning activities (along with reproducible worksheets) that deal with the benefits of wetlands, and some debated issues over wetlands. (TW)

Describes the field work component of a half-term course in environmental chemistry. Discusses the teaching methods used with the students in detecting water pollution. Outlines the activities and experiments in one field trip and presents the results and deductions made by the students. (TW)

This bibliography features a compilation of textbooks, curricular materials, and other marine education resource materials developed by individual Sea Grant programs throughout the Unites States. The listing is intended to be used as a tool for teachers and other individuals interested in helping students explore and understand our oceans and…

"Living in Water" is a classroom-based, scientific study of water, aquatic environments, and the plants and animals that live in water. The lessons in this curriculum integrate basic physical, biological, and earth sciences, and mathematics. The integration of language arts is also considered essential to its success. These lessons do not require…

This teacher's guide offers background information that teachers can use to incorporate topics related to agriculture and the environment into the curriculum. Classroom activities to bring these topics alive for students in grades 6-9 are suggested. Chapters include: (1) Pesticides and Integrated Pest Management; (2) Food Safety; (3) Water…

This 200-page activity guide for educators of students in grades six through university level raises the awareness and understanding of water quality issues and their relationship to personal, public and environmental health.

Discusses some of the contributing factors and chemical reactions involved in the production of acid rain, its effects, and political issues pertaining to who should pay for the clean up. Supplies questions for consideration and discussion. (RT)

A professional school and university collaboration enables elementary students and their teachers to explore hydrology concepts and realize the beneficial functions of wetlands. Hands-on experiences involve young students in determining water quality at field sites after laying the groundwork with activities related to the hydrologic cycle,…

This paper reports on the design and implementation of a project-based course--World Water Problems--that was introduced within the framework of introductory undergraduate geography education. The aims of the course were twofold: (1) to cultivate in students a world geographic perspective on water problems; and (2) to conduct an original research…

Using a context discrimination procedure and rats as the subjects, the formation of context-dependent aversions to novel and familiar fluids was investigated. Experiment 1 revealed that context dependency could be established to a novel fluid (saccharin) after three cycles of context discrimination training and that the acquired context dependency…

An experiment was performed on polymeric-based controlled-release agrochemicals that minimize leaching into groundwater while maintaining an adequate quantity for the desired agrochemical benefits. Gelatin gel containing inorganic Phosphorous provides controlled-release of an agrochemical where release curves show a linear relationship between…

Does agricultural input aid always lead to favourable food security outcomes? This paper describes Zimbabwe's agricultural recovery program for the 2003/2004 farming season and draws some lessons that can be used in the designing and implementation of future programs. Input aid was found to be most beneficial if it is packaged together with other…
