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 the highlights of experiments that allow students to trace the historical development of our understandings of cosmic rays. The experiments provide for two outdoor fieldwork experiences, indoor laboratory work, and an opportunity for a group of students to show originality and initiative. (ZWH)

Describes a freshwater pond study in detail which was done as the biology segment of an interdisciplinary study conference at the Old Railway Pond at National Park. (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 technique by which the density and hunting habits of owls can be inferred from their pellets. Owl pellets--usually small, cylindrical packages of undigested bone, hair, etc.--are regurgitated by a roosting bird. A series of activities based on owl pellets are provided. (CP)

Describes materials and techniques suitable for class fieldwork on the ecology of the cyanogenesis polymorphism of white clover. Details of a school trial are presented and discussed. (Author/EB)

Over 600 students taking advanced level biology in more than 130 schools were surveyed to investigate the relationship between their attitudes toward fieldwork and factors associated with fieldwork teaching. Responses given by the students and their teachers are presented and discussed. (Author/JN)

Described are some experiments on geotropism that may be done using dandelions. (PB)

Different types of spiders, their ranges and habits are discussed. Activities associated with the study of spiders are suggested. Four references are listed which may be of interest to beginners. (CW)

The idea of leaving the classroom and taking students outdoors where no structural boundaries exist can be unnerving for some teachers. Field trip experiences and out-of-the-classroom experiences are important for students. It takes concrete experiences for the students to understand and retain concepts and terms they have read and discussed in…
