Describes an experiment in which the rate of reaction can be followed using a colorimeter and data can be used to determine order of reaction, rate constant, and energy of activation. (GS)

Describes an introductory course in geology for nonscience majors that involves students in laboratory exercises related to rock classification. (GS)

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)

This experiment leads to a value for the ground-state hyperfine splitting of Cs 133, the accepted standard of frequency, to one percent accuracy. (Author/GS)

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

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)
