Describes the characteristics of Colpoda, a ciliated protozoan which is able to survive in a dry, encysted state for long periods of time. Outlines the procedures for culturing the organism and producing cyst preparations, and recommends its use in the high school biology laboratory. (JR)

Describes a field-biology research project conducted at Coos Bay, Oregon by high school students attending the summer sessions at Terramar Field Science Facility during the summer of 1972. Discusses the value of this type of environmental survey for both the students and the community. (JR)

Describes a program initiated by the Cabrillo Beach Museum (San Pedro, California) and the American Cetacean Society to take students of the fourth grade through high school on half-day cruises to observe gray whales. College students assist in the program with related field projects and presentations in the schools. (JR)

Discusses some of the misconceptions that students and instructors have regarding the microscope and provides stepwise instructions to enable the biology student to acquire a sound scientific technique for setting up and using the light microscope with minimal expenditure of time and effort. (JR)

Presents the results of a study designed to determine student preferences with respect to outdoor (natural history) study topics. A primary objective of the study was to obtain knowledge that might assist interpreters and educators to more effectively plan programs and activities that recognize measured predispositions of children. (JR)

Examines the legal and constitutional implications of the fundamentalist movement to win equal time for creation doctrine in science and biology textbooks. (JR)

Describes an individualized general biology course, taught at Marymount College of Kansas, that encourages students to assume responsibilty for their own learning. (JR)

Outlines the proteinoid theory of the origin of life and examines competing or alternative concepts in the light of a sequential experimental model. (JR)

Reports the results of a study which investigated the effects of small-group instruction (as opposed to large-group lecture-discussion) on the achievement and attitude toward life-science of seventh-grade junior high school students. (JR)

Describes a project designed to increase enthusiasm among college human-ecology students for studying environmental problems. Small groups of students were asked to investigate local pollution problems by first discovering them and then filming them with a mobile videotape unit. (JR)

Part one of a two-part article sets forth the dimensions and the political-cultural aspects of the use of off-road vehicles in desert areas. Presents arguments for and against off-road vehicle use on national-resource land as exemplified in the California Desert. (Editor/JR)

Clarifies the difference between the Piagetian Conservation of Liquid Quantity task and the Conservation of Volume task and provides an alternative test for the presence of formal operational thought. (JR)
