We describe a field-based lizard project we did with high school students as a part of our summer Herpetological Research Experiences. We describe data collection on lizards captured, identified, and marked as a part of our mark-recapture study. We also describe other lizard projects that are ongoing in the United States and provide resources for…

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…

Long Island Sound is an estuary of national significance and provides important economic, recreational, and aesthetic value to the citizens of Connecticut and New York. Investigations have been conducted regarding living marine resources and nutrient loading. However, Long Island Sound is often overlooked as an educational resource. This guide is…

Describes an insectary which is inexpensive and easily constructed of small blocks of wood with holes drilled in them. Suggests several areas for study which can be accomplished with the insectary. (SLH)

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

Short articles on a demonstration of enzyme action, models of mammalian circulatory systems, measuring the height of trees, the ecology of the African amphibian Xenopus under natural conditions in England, experiments with liverwort gemmae, investigations using stick insects, and a culture medium for Paramecium bursaria. (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)

Collecting, handling, and preserving insects reveals many things which books fail to cover, and field trips often prove to be excellent catalysts in developing young entomologists. (Author/DF)

Describes an activity for biology students designed to involve them in working with the National Park Service in the determination of the effects of fire on black oak reproduction and subsequent survival. (PEB)

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)

Outlines simple statistical procedures that may be effectively used in several ecology exercises suitable for secondary school science classes. (JR)
