Directions for constructing a hand glider out of free or inexpensive materials are combined with measurements, tests and recordings of its flight done in metric units. (BR)

Utilizes a rotating table and strobe photographs to provide students with a direct record for quantitatively analyzing rotational effects. (GS)

Gives the justification, text, and examples of two recordings illustrating the phonetic oppositions of four French vowels. The tapes were produced and tested at the Universite de Lausanne, and are intended for language laboratory use. (Text is in French.) (MSE)

Argues that instructor monitoring in a language laboratory is an inefficient instructional method. (CK)

A science toy sometimes called the "magnetic spinner" is an interesting class demonstration to illustrate the principles of magnetic levitation. It can also be used to demonstrate Faraday's law and a horizontally suspended physical pendulum. The levitated part contains two circular magnets encased in a plastic housing. Each magnet stays…

The objective of this paper is to design a train of tubular reactors that use a methane feed to produce hydrogen of the desired purity so that it can be utilized by a fuel cell for automotive applications. Reaction engineering principles, which are typically covered at the undergraduate level, are utilized to design this reactor train. It is shown…

Describes activities dealing with the surface tension of water designed to capture interest and raise questions in students. (BR)

Outlines the construction, basic principles, calibration, and laboratory application of a device for the investigation of static charge phenomena. (GS)

Describes an easily-implemented experiment in which a moderately complex relation between dependent and independent variables is involved. (Author/GS)

Describes an experiment suited for use in an advanced laboratory course in particle physics. The magnetic moment of cosmic ray muons which have some polarization is determined with an error of about five percent. (Author/GS)
