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)

Discusses the advantages and disadvantages of a specific method of bacterial identification and suggests some modifications or improvements. The approach is presented as being suitable for obtaining information about the diversity of bacterial types on student fieldwork. (Author/EB)
