Presents an investigative sequence of experiments addressed to the topic of photosynthesis. (BR)

A report of the growth and present status of the mini-computer based, time sharing laboratory at the University of Indiana, which describes the system hardware, software, and applications in psychological experimentation. (EH)

Describes construction of a pinhole camera with simple materials and five experiments to be conducted, as well as instructions in creating a working camera obscura. (BR)

Illustrates some important characteristics of photosynthesis, concentration dependencies of reaction rates, temperature effects, and effects of changes in actinic wavelength. (GS)

Weights suspended from a lever arm separate evacuated hemispheres allowing estimation of atmospheric pressure to within five percent of the barometric reading. An illustration and a reference to von Guericke's demonstration are provided. (GH)

Describes a project to produce a series of laboratory manuals and instructional materials in which nuclear experiments are presented for the undergraduate advanced laboratory. The manuals are being compiled in the areas of physics, chemistry, geology and environmental sciences. (BR)

Describes a method (involving a Hach Colorimeter and simplified procedures) that can be used for the analysis of up to 56 different chemical constituents of water. Presents the results of student analysis of waters of Fulton and Montgomery counties in New York. (GS)

Gives a brief survey of the different versions of the air trough and related devices. Presents some of the applications of this equipment in the teaching of the concepts of inertia, acceleration, and velocity. (GS)

Directions are given for the construction of a manometer to measure animal metabolism. Steps in an experiment to measure frog metabolism are specified. (DT)

Describes the use of bio-medically significant materials to teach a self-pacing chemistry laboratory course to nursing majors. Indicates that the student can learn from the course to determine values of body fluid constituents, about their variations among healthy populations, and about difficulties inherent in making such measurements.
