Students learn science best with activities that mirror the way scientists work. This article describes how geologists investigate groundwater flow systems in areas of karst topography--geologic formations shaped by dissolving bedrock--and provides a way for students to replicate this research. Students also use electric current to model water…

Field studies are an excellent way for students to learn ecological concepts and practice doing science. This article presents an approach for the secondary science classroom that permits students to ask and answer their own questions, a prerequisite for truly experiencing the process of science. Students explore a local natural area and, in…

Describes an earth science project completed by students in an American school in Saudi Arabia. (AL)

Described are some uses of a 35mm single lens reflex camera as a tool for the applied study of ecology. Photography is discussed in relation to field trips, ecosystems, general ecological concepts, pollution, and special projects. (PEB)

Describes archeology as a discipline and explains the interdisciplinary approach being used to explore the Koster excavations in Illinois. Four programs involving direct student participation in archeological research are outlined as well as the major findings at Koster and their contribution to interdisciplinary archeology. (BR)

Describes a cooperative program in Ohio which involves the Ohio EPA, universities and public schools all involved in water testing. The philosophy of the program is based on students investigating a problem, applying science tools to understand the problem and then using the social sciences as instruments to affect change. (BR)

Describes teaching ecology by using highway travel. Provides an outline for the travel observation checklist. Discusses some practical information for using the activity. (YP)

Describes an environmental simulation exercise conducted at an outdoor camp in Colorado. The two simulations involved the physical, social, political and environmental factors which might influence construction of an airport in the Rocky Mountain National Park and factors associated with a nuclear generating plant. (BR)

Describes a six week summer course for junior high school students designed to acquaint them with one of the many branches of oceanographic studies. (PB)

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)

Pollination vectors of a variety of types are described including beetles, bees, flies, moths, birds, bats, and the wind. Some of the adaptations of plants designed to help facilitate pollination are discussed. Strategies for incorporating this information into a lesson plan are suggested. (CW)

Described is a field trip in which eighth grade earth science students map the rock types located on the side of a mountain. Pretrip preparation, equipment, procedures, and posttrip analysis are discussed. (CW)

Suggests integrating creative writing activities into field trips or outdoor education experiences in science as a method of providing "right-brain" and "left-brain" activities in the same exercise. Provides instructions given to students and a poem written from student "photographs" using imaginary cameras. Also provides two student poems. (JM)
