Describes the difficulties that arise from teaching science to mixed ability groups where individualized instruction is emphasized. (BR)

Describes laboratory exercises with chickens selecting their food from dyed and natural corn kernels as a method of demonstrating natural selection. The procedure is based on the fact that organisms that blend into their surroundings escape predation. (BR)

Describes the use of storage oscilloscopes in five physics experiments, in lecture demonstrations, and in improved measurement techniques. (GS)

The role of environmental stimuli in the control of cigarette smoking has been the object of theoretical speculation, but there have been few experimental demonstrations of the control exerted over smoking by environmental events. Self-report data on smoking in the natural environment were compared to observations made of smoking among subjects…

These guidelines are intended to assist high school psychology teachers in safeguarding the rights and welfare of students and experimental subjects while promoting high-quality instruction. There are three sets of guidelines. The first set deals with the use of animals in school science behavior projects. The major goal of such projects should be…

Twelve science activities involving the common paper food bag and the small plastic food bag are described. (DT)

Describes an experiment which can be used to test for the use of accelerants in the origin of a fire. Involves distillation and gas liquid chromatography to identify the accelerants, thus combining two experiments ordinarily included in the beginning organic laboratory. (SLH)

Describes the use of student projects within a traditional biology laboratory class to incorporate openness, inquiry techniques, and student choice into course teaching. Included is a list of sample investigations. (CC)
