Provides a listing of articles and papers published in 1976 relating to various fields of biology and presents various biological science activities. (SL)

Presents experiments using wild birds as predators and pastry as prey and colored stones as background to demonstrate natural selection. Describes the exercise as an exercise in simulating natural selection. (Author/CW)

This study sought to determine which journals are read by Texas life science teachers and the relationship between reading practices and sex, teaching certification, professional degree attainment, and teaching experience. (MNS)

The purpose of keeping animals in schools and problems encountered in their maintenance are summarized. Two curriculum units, one on fruit flies and one on honey bees are described. Reasons for a widespread negative image of rural studies are discussed and positive outcomes of an environmental science course are presented. (Author/EB)

Outlined is a water ecology unit included within a one-semester field biology course for upper level high school students. Activities described include a visit to a water treatment plant, an abiotic stream study, a biotic stream study, interactions and questioning topics, and individual projects. (CS)

Described is a school project to investigate aggregations in flatworms which may be influenced by light intensity, temperature, and some form of chemical stimulus released by already aggregating flatworms. Such investigations could be adopted to suit many educational levels of science laboratory activities. (DS)
