Describes experiments for determining the dielectric constants of liquids and measuring capacitor dissipation. (SL)

Describes an experiment using flow densimetry for determining the solution concentration in equilibrium with the excess solid solvent present. (SL)

Describes an inexpensive device for students to measure Planck's constant using the photoelectric effect. (SL)

Describes experiments simulating the mechanics of the human elbow and back. (SL)

Presents results of analyses of flat and conical depressed target surfaces used in a bouncing ball experiment. (SL)

Describes experiments demonstrating the Josephson effect, single-file diffusion in biological membranes, refractive index of beer, lines of magnetic fields, indexing diffraction patterns, Maxwell's equations, and spherical aberration. (SL)

Cites several examples of research studies in which medical as well as ethical considerations affected the treatments prescribed. The ethical versus the statistical aspects of drug testing are also discussed. (CP)

These experiments attempt to optimize the possibility of demonstrating blocking in a taste-aversion paradigm and to elucidate the conditions under which this interference occurs. (Author/RK)

To complement investigations of the direct effects of lithium toxicosis on consummatory behavior, these experiments were designed to determine the aftereffects on drinking of exposure to a conditioned stimulus previously paired with lithium. (Author/RK)

In four different experiments, brief illumination of a localized visual stimulus was followed by grain presentation unless the pigeon approached the light. Results indicate that although response-reinforcer relations do play a role, stimulus-reinforcer contingencies are the dominant factor in establishing and maintaining approaches to the…

Describes a chemistry laboratory activity for determining the best procedure for analyzing iodide in seaweed. (SL)

Describes a method of determining the molecular weight of a weak acid. (SL)

Describes four experiments in mechanics which utilize a tennis ball serving machine. (SL)

Describes the inception, use, and evaluation of a demonstration laboratory designed to enable first-year university students to observe physical phenomena that they did not observe in the secondary school. (Author/SL)

This paper is addressed to the process of learning to retrieve learned verbal material. Retrieval itself may be viewed as involving a plan or strategy for recovering the appropriate material in the particular situation for recall. (Author)
