Describes the procedure for making a quantitative analysis of organic compounds suitable for secondary school chemistry classes. Using the Schoniger procedure, the organic compound, such as PVC, is decomposed in a conical flask with oxygen. The products are absorbed in a suitable liquid and analyzed by titration. (JR)

Includes ten topics relating to laboratory activities, experimental procedures, and teaching materials suitable for secondary school physics classes. (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)

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)

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)

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)

Describes a project involving the integration of inorganic and organic chemistry by a study of copper determination involving an organic complex. (TS)
