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)

Describes an experiment, easily repeated in the classroom, designed to determine whether members of the species Drosophila melanogaster show selective preference in choice of mates. (PEB)

A number of activities are described by which a class can collect biological data about the students in the class. Brief instructions are given. (RH)

This second report from the Analytical Chemistry Subcommittee presents ideas for using real-life samples for student analysis and for introducing the topic of developing procedures for analysis. (DT)
