Article focuses on defining the role of demonstration in general and experiments in particular in science education at the high school level, on the basis of psychological data and recent conceptions about the nature of science. (Author)

A way of teaching the scientific method to elementary pupils, using animal life collected by students. (SP)

Discusses a course, centered around 32 experiments taught for advanced students, designed to develop a laboratory strongly suggestive of contemporary research using relatively sophisticated apparatus. Its unique advantage lies in enriching advanced physics curriculum. (DF)

A multidiscovery, open-ended, sciencing experience appears to have implemented nearly the full spectrum of cognitive, affective, and psychomotor objective domains.'' (Author/DF)

A description of a field experience to demonstrate some basic principles concerning the geologic transport of beach sands. (Author/CP)

Describes the use of laboratory equipment to demonstrate (1) the interference of light coming from an air wedge, (2) the generation of gas-filled soap bubbles, and (3) the generation of beats with a ripple tank. (LC)

Procedures for using soap films to determine the shortest series of lines connecting several points. (CP)

Describes a novel instructional method for physics involving the use of a computer assisted instruction system equipped with cathode-ray-tube terminals, light pen, and keyboard input. Discusses exercises with regard to content, mediation, scoring and control. Several examples of exercises are given along with results from student evaluation. (LC)

Describes a method for the extraction and bioassay of natural germination inhibitors, requiring only inexpensive equipment and minimal experimental skill. The method has been used to demonstrate qualitative/quantitative differences in germination inhibitor levels in a variety of different fruits or in different tissues within a single fruit.…
