Describes simple ways of measuring the very local climate near the ground, and explains what these measurements mean. Equipment included a solar radiometer, a dew point instrument, and a thermocouple psychrometer. Examples are given of field measurements taken with some of the equipment and the results and their interpretation are discussed.…

Describes an exercise that illustrates the synthesis of an amino acid and Michael type condensation. The exercise can be used with college students of chemistry or biochemistry. (HM)

Describes a three-day program aimed at public school educators and community leaders. The goal was to encourage these people to include air age education in their programs. Activities included hands-on projects. (MA)

Lists 17 activities that can be used in the classroom to commemorate Wright Brothers Day. These include making bulletin boards, writing poems, and a field trip to the airport. (MA)

Lists several ideas for experiments for the amateur scientist to try or design. The list covers a wide range of topics; sound, mechanics, thermodynamics, fluids, optics, and electrostatics. (GA)

Discusses the adaptation of some familiar equipment for use in physics demonstrations: demonstrating waves using a folding slinky, measuring the partial pressure of water vapor, lengthening the time constant on a rate meter, measuring "g" with a phonograph turntable, and constructing a cheap signal generator. (GA)

Provides eight physics experiments, demonstrations, and activities relating to radioactive decay, computers, semiconductors, and electronics. (SL)

Presents the international flag and pennant code and suggests a variety of classroom uses of this means of communication. (CP)

Describes a computer simulation to elucidate the subject of coherence. The model on which simulation is based links coherence to the correlation of fields. It also describes the model and presents some results. (Author/GA)

Discusses the solubility characteristics of bromine salts. (CP)

Data reveal that the absorption spectra of alkali metals can be analyzed using a modified laboratory procedure. ( CP)

Tested demonstrations on (a) color development through the formation of subtractive primary dyes and (b) fluidity of gases are presented. (CP)

Describes the modification of a transistor radio to make an audio oscillator. (SL)

Describes a method of making simple transmission gratings by photographing the interference fringes generated by an interferometer. (SL)

This paper draws attention to cart wheels, two wheels rotating freely about a common axle and rolling on an inclined plane, both as a demonstration and as a satisfying application of dynamical analysis. (BB)
