Describes a simple method of demonstrating the Bernoulli effect, by spinning a length of rubber tubing around one's head. A manometer attached to the stationary end of the tube indicates a reduction in pressure. (JR)

Outlines several exercises suitable for elementary science classes which may be used to illustrate objective experimental analysis. (JR)

Describes experiments using crude isolated chloroplast fractions which demonstrate some aspects of the photosynthetic light requiring process and a number of factors affecting them. These experiments are suitable for senior high school and college courses in biology. (JR)

A simple experiment is proposed that can provide the student with some insight into the chemical properties of solids. It also demonstrates the relationship between the Gibbs free energy of formation of an ionic solid and the emf of an electrochemical cell. (DF)

Describes an experiment designed to expose the student to the classical techniques of organic dye synthesis and introduce him to a variety of modern scientific knowledge and exotic physical phenomena which he might not encounter otherwise. (Author/DF)

Describes the pedagogical use of a 12.0m x 1.0m x 0.8m electromagnet to demonstrate the properties of magnetostatic fields and the Faraday-Henry induction law. (CC)

The shore crab (Carcinus maenas) is an excellent subject for school study, both in the field and the laboratory. It is easily collected and maintained and can be used for a wide range of investigations. Some background details are given and possible areas of investigation suggested. (Author)

Describes an experiment to examine the kinetics of carbamate decomposition and the effect of buffer catalysis on the reaction. Includes background information, laboratory procedures, evaluation of data, and teaching suggestions. (Author/JN)
