Test performance and attitudes of freshman medical students exposed to various methods of instruction in a biochemistry laboratory are compared. (Editor)

Describes the content and organization of a laboratory session in which student teams work on the organs, tissues, and parasites of a pithed frog. The procedure maximizes participation by every student, makes possible the fullest use of each frog, and permits a rather broad study in a limited time. (JR)

The question of whether modern experiments are limited by the uncertainty principle or by the instruments used to perform the experiments is discussed. Several key experiments show that the instruments limit our knowledge and the principle remains of strictly academic concern. (DF)

Contains text of a speech presented at one of eight 2-day forums which discusses the contribution industrial arts should make to a total program of education. (Editor/SB)

An independent study project is launched for eighth graders which allows students to perform various activities including laboratory experiments, laboratory search, and interpretation of data. Program is well received by people involved. (PS)

Gives the findings on which the Institute's judgments were based. Facts are arranged by characteristic -- physical description, electrical and optical characteristics, operating features, and safety and maintenance factors. (Author)

Describes a one-semester biology course for nonmajors which explores the interdisciplinary potential of psychology, anthropology, history, literature, philosophy, and religion. Satisfactory results in the 1970 tryout with 126 college students are identified. (CC)

Experiments conducted on wheat and barley grains to analyze activities of alpha- and beta-amylase enzymes. Gibberellins were used exogenously. Techniques are described in detail. Results on different cultivars revealed that beta-amylase was not an invariable result of imbibition. Techniques employed can be used by school students. (PS)

Twelve new chemistry expermiments are described. Broad areas covered include atomic structure, solubility, gaseous diffusion, endothermic reactions, alcohols, equilibrium, atomic volumes, and some improvised apparatus. (PS)

Seventeen experiments in physics are described to demonstrate various physical phenomena. These include the areas of velocity of sound, damped oscillations, plastic deformation of wires, materials, testing, air resistance, spectrum optical filtering, and some new improvised apparatus. (PS)

Experiences and experiments with mirrors will spark pupils' imaginations while providing insights into the nature and behavior of light. (Author/DF)
