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)

Without building costly new plants, the College High School plan can be implemented. This plan provides the kind of climate usually associated with colleges, where students accept major responsibility for selecting courses, choosing teachers, and managing free time. (Editor)

Reports an investigation to determine whether or not interaction analysis could be used as a tool to analyze laboratory instruction and to identify patterns of instruction which differentiate effective and ineffective teaching. Indicates student performance can be enhanced by a student-centered climate. (Author/TS)

In this, the sixth year of recording academic library building data, it is possible to begin a yearly appraisal of change, progress or decline by comparison with the five-year base data published last year. (Author/NH)

Using a new self-instruction approach'' and tapes from government sources, a college can now afford to offer courses in nearly every foreign language.'' (Editor/SP)
