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 a project for secondary school students in environmental education. The eight week unit focused the study of a creek and the related environment. (RH)

Describes a device that simulates the scales and motions involved in the observer coordinate system. (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 activities involving the use of playground equipment (such as swings and seesaws) as a means of teaching elementary school children some basic principles of physics. (JR)

Describes a method for introducing and teaching to junior high school students the concepts involved in constructing a dichotomous key. (JR)

Describes activities using "Hot Wheels" cars as a means of introducing concepts of friction, inclined planes, and kinetic energy to elementary school children. (JR)

Describes a science activity, using safety pins, illustrating steps in problem solving. (PEB)

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)
