Suggests that differential rearing conditions may cause significant reversals in sex-related ability and behavior (maze learning and exploration), and may significantly affect perceptual sensitivity. (RL)

Gives four science lessons for third graders concerning combustion, density, static electricity, and air pressure and surface tension. (RH)

Describes an experiment on heat that utilizes only a styrofoam cup of coffee and a soda straw thermometer. (BT)

Describes a simple method of measuring the refractive index of a liquid using a paper cup, a liquid, a pencil, and a ruler. Uses the ratio between the actual depth and the apparent depth of the cup to calculate the refractive index. (GA)

This experiment designed for beginning physics students, is related to postal regulations restricting the size of envelopes. A graph is constructed that allows for testing the mailability of envelopes. (MP)

Reports and summarizes some of the findings of a conference, held in Oxford in July 1978, to discuss the role of the laboratory in physics education. (GA)

The gravimetric determination of calcium as calcium carbonate is described. This experiment is suitable for undergraduate quantitative analysis laboratories. It is less expensive than determination of chloride as silver chloride. (BB)

This demonstration uses the electrophoresis of indicators to demonstrate the principles involved in the separation of isoenzymes. (BB)

Describes the controversy over the hidden variable in quantum mechanics, especially over Bohm's theory, and the criticism and rejection it received as a result of the erroneous application of Von Neumann's impossibility proof, rather than Bohn's theory itself. Concludes that science, especially physics, is not permeated by social factors. (GA)

Describes an experiment to characterize the enzyme polyphenol oxidase. Includes Purpose, Reagents and Equipment, Procedure, Extraction, Treatment of Data, and Discussion. (MA)

Presents the use of a Michelson interferometer in studies of visible spectroscopy. Discusses the experimental setup for obtaining reflectivity spectra of various semiconducting materials. (MLH)

Describes an experiment in which Fresnel diffraction patterns were observed with a beam of slow neutrons of wavelength 4.33 Angstroms. (MLH)

Describes an experiment that utilizes fluorescence intensity measurements from a Spectronic 20 to determine the rate constant for the fluorescence quenching of various aromatic hydrocarbons by carbon tetrachloride in an ethanol solvent. (MLH)

Explores the possibility that measurable individual differences in hypnotic susceptibility or the ability to attend selectively to informational cues may account for a portion of the variability found in several types of geometrical visual illusions. (Author/RK)

Examines whether self-consciousness, a personality disposition, affects self-attributions and attempts to replicate the research findings of Duval and Wicklund (1973) that self-awareness affects self-attributions. (Author/RK)
