Describes a science study tour that included visits to eight European cities. Lists visits to science museums, research centers, and educational institutions. (MLH)

Discusses and clarifies the confusion arising from the use of the terms "mass,""volume,""matter,""mole," and "Avogadro's number." Suggests three laboratory activities concerning mass, volume, and number of particles in a given volume. (CS)

Describes an exercise that extends the actual determination of the amino acid sequence of a simple dipeptide to the theoretical determination of the complete primary structure of a larger polypeptide. Includes diagrams of display cards and duplicated sheets used in the theoretical portion of the exercise. (CS)

Suggested are activities using a Polaroid camera to illustrate the capabilities of remote sensing. Reading materials from the National Aeronautics and Space Administration (NASA) are suggested. Methods for (1) finding a camera's focal length, (2) calculating ground dimension photograph simulation, and (3) limiting size using film resolution are…
