Presented and discussed is a program for a programable calculator that predicts the altitude achieveable by a model rocket. (MP)

Looks briefly at the abilities of children within the ages of three and thirteen and at movement and dance appropriate for them. (Author/RK)

Considers the problem of the radiation emitted by a charged particle undergoing eternal hyperbolic motion. (Author/SL)

Through simple and pleasurable movement experiences a very young child can be led to an understanding of the intricate craft of music and the signs and symbols of the music "language", while developing at the same time an increasing appreciation and perception of music as an artistic expression. (Author)

Discusses how the discovery of chaos has created a new paradigm in scientific modeling and how findings are contributing to changes in thought about many different branches of science. Includes explanations and examples of how chaotic behavior can be understood. (ML)

Explains the phenomenon of Brownian motion, which serves as a mathematical model for random processes. Topics addressed include kinetic theory, Einstein's theory, particle displacement, and others. Points out that observations of the random course of a particle suspended in fluid led to the first accurate measurement of atomic mass. (DH)

Shows that the angle of projection of a bullet is not the same as the angle of the bore of the firearm just before firing. Includes an equation that is useful when considering the firing of bullets and arrows in the air. (JN)

Presents an experiment which focuses on the inertial properties of a rigid body as expressed in terms of principal axes and moments of inertia. Background information, a description of the apparatus needed, and a discussion of results obtained are included. (JN)

Describes two studies of five- to nine-year-old children. Study 1 illustrated a low incidence of animistic thought and indicated the salience of movement in a group of northern, Unitarian children. Children demonstrated a variety of criteria for aliveness. Study 2 replicated findings in a group of southern, Baptist children. (Author/KS)

Describes how to record and study two-dimensional collisions using video-recording equipment. These techniques have been used by students in a calculus-based physics laboratory for such experiments as the analysis of conservation of momentum on the airtable. (JN)

Discusses the subjective relativity of the term "up" and its relationship to an observer's acceleration. Provides examples from amusement park rides and literature, and describes a demonstration using a Fletcher's Trolley. (JM)

Discusses the relationship of gravity, coefficient of friction, surface area, and Newton's second law to explain the physics involved in downhill skiers being able to move faster than sky divers in free fall. (JM)

The author advocates changing the traditional approach to mechanics from emphasis on the formulation of Newton's Laws to discussion of the foundations of mechanics and Mach's formulation. (SD)

Describes a pedagogical method for measuring the coefficient of restitution for collisions between a bouncing ball and a horizontal surface by measuring the sound made by the bouncing ball. (MLH)

This research aims to study the ways in which "local" events of randomness, based on experiencing the outcome of individual events, can be developed into "global" understandings that focus on an aggregated view of probability (e.g. probability of an event). The findings reported in the paper are part of a broader study that adopted a strategy of…
