Activities in this packet were developed in reference to research conducted at the U.S. Environmental Protection Agency's Mid-Continent Ecology Division in Duluth, Minnesota (MED-D). The research helps us better understand the effects of pollutants on freshwater systems such as lakes, rivers, and streams and determines how we can best keep these…

This guide provides teachers with materials, information, and classroom activities to enhance any drinking water curriculum. Students can use the activity sheets to further lessons and stimulate thought. Parents can use the guide to develop science projects that will provoke thought, encourage research, and provide a scientific approach to…

Describes water-related activities in an elementary school science project. These activities focus on electric generators, rainfall, erosion, floating, water conservation, and other areas. Brief comments on developing such a project are included. (JN)

Presents two activities on acid rain for students in intermediate grades. Materials needed and procedures used are included. Also describes "chemical magic" shows performed by high school students for sixth-grade students in seven elementary schools in Altus, Oklahoma. (JN)

This teacher's guide attempts to answer questions such as: What causes ocean currents? What impact do they have on Earth's environment? and How have they influenced human history? Seven innovative activities are provided in which students can gain fascinating insights into the earth as the ocean planet. Activities focus on how wind, temperature,…

Described is an advanced biology class project involving study of the effects of organic pollution on an aquatic ecosystem from an sewage treatment plant overflow to evaluate the chemical quality and biological activity of the river water. (DS)

This collection of teaching units were selected from materials developed during the Operation Pathfinder Institutes (OPI) which took place in the Pacific region between 1994 and 1999. The institutes were intended to provide upper elementary and middle school science teachers with an opportunity to develop a deeper understanding of the marine…

Highlights several basic ecological principles and suggests corresponding classroom activities for grades five to eight that revolve around a freshwater aquarium. Basic ecological concepts, adaptations, characteristics of aquatic habitats, and pollution problems are outlined in separate tables. A short list of resource materials is included.…

Provided are details for a game designed to help secondary school or college students understand the types of problems encountered in applied hydrobiology and the financial and time constraints involved in their solution. (PB)

Twenty-three activities dealing with various aspects of groundwater are provided in this manual. The activities are arranged under four headings: (1) the water cycle; (2) water distribution in soils (considering such topics as calculating water table depth and purifying water by filtering); (3) water quality (considering such topics as acid rain,…

Describes a two-day field trip, along with follow-up classroom activities and experiments which relate to water resources and water quality. Discusses how trips to a lake and water treatment facilities can enhance appreciation of water. (TW)

Describes a project involving students in hands-on scientific experiment to locate and identify areas of water pollution, based on Delta Laboratories Adopt-A-Stream Program. Describes getting started, working cooperatively, community support, recording and using data. Includes data sheet, checklist, and photographs of students at study site. (TES)

A bibliography of marine-oriented commercial and public domain courseware has been maintained by the Computer Education Committee of the Mid-Atlantic Marine Education Association for several years. This compilation is provided to interested persons by an established network with the following purposes: (1) to review and critique commercial and…

Encourages instruction about disposal of hazardous wastes in college chemistry laboratories as an integral part of experiments done by students. Discusses methods such as down-the-drain disposal, lab-pack disposal, precipitation and disposal, and precipitation and recovery. Suggests that faculty and students take more responsibility for waste…
