The origin of the design of model rockets and spaceships based on Universal Studio's, "Buck Rogers in the 25th Century" is described. (SA)

A device designed for sampling algae in rivers and streams is described. Techniques for observing algae in the laboratory as well as tips for maximizing success in sampling are given. (SA)

Describes three accessories developed to be used in conjunction with the rotating platform or turntable. Three demonstrations using these accessories are included. These demonstrations are: (a) conservation of angular momentum; (b) gravity-defying goblets; and (c) direct measurement of centripetal force. (HM)

Explains two approaches to the automatic arrest of a potentiometric titration. (SA)

Presents part two on the use of the detection of thermoluminescence as an analytical tool for the chemistry laboratory and allied science. This part discusses instrumentation used and investigates recent developments in instrumentation for thermoluminescence. (HM)

Describes a physics laboratory for college students, in which the students participate in a firsthand noninertial experience. The equipment and problems are described. (SA)

Describes how to grow mimosa plants from seed, how to grow large crystals, and how to construct a simple electric motor. (MLH)

Describes: how to measure index of refraction by the thickness method; how to teach the concept of torque using a torque wrench; how to produce a real image with a concave mirror; how to eliminate the interface effects of a Pyrex containers; and an apparatus to illustrate Bernoulli's Principle. (MLH)

Describes four outreach programs that connect businesses and post-secondary institutions with schools and their science curricula. Mobile science laboratories provide services and access to science equipment to students and their teachers. (DDR)

Instructions for the construction of this instrument and its use are presented. The use of common materials is emphasized. (CW)

Explains strategies for motivating and getting student's attention in science. Presents a laboratory procedure for generating hydrogen using an Erlenmeyer flask and a one-holed stopper apparatus to fill a balloon which is used to produce a dramatic explosion. Safety precautions are cited. (RT)

Describes a thin film rectangular dielectric waveguide and its laboratory use. Discusses the theory of uniaxial thin film waveguides with mathematical expressions and the laboratory procedures for a classroom experiment with diagrams. (Author/YP)

Discusses laser demonstration for invoking interest in science, especially physics. Describes some examples, such as diffraction, scattering, expansion by diverging lens, internal reflection in a light pipe, and illumination through optical cable. Provides some practical hints for the demonstration. (YP)

Described is a demonstration of Snell's law using a laser beam and an optical fiber. Provided are the set-up method of the demonstration apparatus and some practical suggestions including "index matching" technique using vaseline. (YP)
