Describes the development of a unit on alcohols for high school chemistry students. Learning activities were heavily based on previous experiences. (PS)

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)

Instructional uses of paper are described. Some of these include tensile strength, water absorbtion, fish study, functioning of eye lenses, and flotation. (PS)

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)
