Briefly describes some experiments which give indications that neutrinos may not be massless particles. (SK)

Presented are two lessons which illustrate acceleration for elementary school students. A poster for use in these activities is provided. Teaching methods used in these lessons are discussed. Student questions concerning automobile racing are presented with answers. (CW)

The use of computer spreadsheet programs in the physics laboratory is discussed. An example of this application with a conservation of energy laboratory is presented including the cases of a rolling sphere and a sliding sphere. (CW)

Examines the relationship of the amount of available short-term memory with the complexity of tasks the subjects mastered. Presents some hints for a better design of instruction. (YP)

Describes three demonstrations showing chaotic motion, which makes long-term prediction impossible. Discusses the apparatus for the demonstrations and procedures for illustrating chaotic motion of pendulum, balls rolling in a double potential well, and a ball rolling on a balanced beam. (YP)

Evaluates 10 courseware packages covering topics for introductory physics. Discusses the price; sub-topics; program type; interaction; possible hardware; time; calculus required; graphics; and comments on each program. Recommends two packages in projectile and circular motion, and three packages in statics and rotational dynamics. (YP)

Describes an experiment to determine the density of air within a 10 percent error range using a basketball and a triple beam balance. Provides the typical data and a graph. (YP)

Describes the nature of cognitive research. Misconceptions research in mechanics and electricity are reviewed. Research results on expert/novice differences in knowledge organization and problem solving are reviewed. Implications for classroom teaching are discussed. Lists 34 references. (YP)

Describes three demonstrations: (1) "A 'Rocket' Cart" (using a fire extinguisher and a child's truck); (2) "Angular Momentum Conservation" (providing materials and calculations); and (3) "Cavendish Experiment" (including the building method and examples of calculations). (YP)

Develops an experimental teaching method emphasizing the nature of functions including graphical representation in an introductory college physics course (mechanics). Examines the effects of this method on student's problem solving and attitude toward physics. (YP)

Explains reasons why students have misconceptions concerning pendulum swings. Presents a series of 10 pendulum task cards to provide middle-school students with a solid mental scaffolding upon which to build their knowledge of kinetic energy and pendulums. (PR)

Describes an experimental sequence using the force probe to develop the relationship between net force and acceleration. (PR)

Suggests ways to bring home to the introductory physics student some of the excitement of recent discoveries in particle physics. Describes particle detectors and encourages the use of the Standard Model along with real images of particle tracks to determine three-dimensional views of tracks. (MVL)

Describes a set of hands-on corridor demonstrations that illustrate various aspects of interference and diffraction of light waves and sound waves. (11 references) (JRH)

Presents a 12th-grade class project on measuring velocity-dependent forces encountered in two common forms of locomotion--rollerblading and cycling. (WRM)
