Uses the problem of determining when a car and truck traveling at the same speed will collide after the truck has applied its brakes to illustrate the need to consider boundary conditions when solving problems in elementary mechanics. (MDH)

Presents an activity designed to show how water temperature affects evaporation, condensation, and the water cycle. Demonstrates how thermal energy can cause phase changes and motion. (Author/WRM)

Introduces an integrated unit on scuba science. Studies oxygen in kinetic theory, Boyle's law, Charles's law, Dalton's law, human circulatory and respiratory systems, and diving dangers such as decompression sickness. (YDS)

Describes a project in which elementary students develop their science understanding and literacy skills by developing their own book on the topics of solids, liquids, and gases. (WRM)

Provides an art project for use with eighth-grade students, who choose a work of art and recreate it in an interpretive and informative manner. Explains that students re-create the background of the artwork and then the students become a part of the painting via characters or objects. (CMK)

In a mental rotation task, children 5 and 6 years of age and adults had to decide as quickly as possible if a photograph of a hand showed a left or a right limb. The visually presented hands were left and right hands in palm or in back view, presented in four different angles of rotation. Participants had to give their responses with their own…

Several years ago U.S educators realized that they were not encouraging young girls in math and science. Today girls are catching up, but another void in classrooms has appeared. Some children, especially high-energy boys, face increasingly inappropriate programs, which offer lots of seatwork and little movement. It is as if some teachers are…

The consciousness of dizygotic twins in their communication of actions and events as seen in the visual cliff pictures published by E. J. Gibson and R. D. Walk (1960) was studied in Sweden. In the process of communication, many different state spaces are generated. The methodology demonstrates that ecological and biophysical properties of language…

This unit on the gaseous state is one of 10 first year units produced by the Independent Learning Project for Advanced Chemistry (ILPAC). The unit consists of two levels. Level one deals with the distinctive characteristics of gases, then considers the gas laws, in particular the ideal gas equation and its applications. Level two concentrates on…

Describes programs that have been developed to allow kinetic experiments to be simulated on a small computer. Reports the principles that have guided the conception of the programs and describes an instance of their application to a complex reaction. (Author/GS)

This concept module on force transformers is one of thirteen modules that provide a flexible, laboratory-based physics instructional package designed to meet the specialized needs of students in two-year, postsecondary technical schools. Each of the thirteen concept modules discusses a single physics concept and how it is applied to each energy…

The fifth and final volume of a series concerned with higher educational facilities planning expands the discussion of the utilities planning process initiated in the overview of volume one. Three major classes of utilities--energy utilities, service utilities, and communications utilities are studied. Their influences on the overall physical…

As the fourteenth lesson of the Articulated Multimedia Physics Course, instructional materials are presented in this study guide with relation to gases, gas laws, and absolute temperature. The topics are concerned with the kinetic theory of gases, thermometric scales, Charles' law, ideal gases, Boyle's law, absolute zero, and gas pressures. The…

Movement is a natural part of life, and body and mind should develop together. (JD)
