Describes four kinds of movement by a cat with or without angular momentum and tail or tail-less during free falling. Presents many pictures illustrating the movement. Supports the position that the angular momentum of the tail plays an important role in free fall. (YP)

Describes Unified Science Technology, an approach to technology education in which the application of science concepts (such as chemistry or physics) to technology is explored. (SK)

Separatists and Fundamentalists share common goals: to establish true religious neutrality in the schools and to eliminate the stranglehold of the American Civil Religion. Since schools cannot separate themselves entirely from religious issues, the solution may be to include more courses in comparative religion and philosophy. Includes 13…

Explains why the isolated sphere models are physically unsound. Describes an improved model for attempting a qualitative explanation of charge concentration. (YP)

Compared is the mass of a dozen eggs with the mass of air in an empty refrigerator. An answer and reasons for the answer are provided. (YP)

Discusses the applications of the principles of mechanics to rock climbing techniques. Provides illustrations showing the applied force vectors. (YP)

Presents activities that allow students in grades three to five to study sound by using children's tradebooks during exploration and experimentation. (JRH)

Presents hands-on science activities that help young children learn about the five senses and connect different aspects of the early childhood curriculum. (JRH)

Discusses interesting aspects of the Carnot cycle and other thermodynamic cycles that are generally not dealt with in elementary physics texts. Presents examples that challenge the student to think about the extraction of net work from a cycle. (JRH)

Presents the theory behind the mechanics demonstration that involves projecting a ball vertically upward from a ballistic cart moving along an inclined plane. The measured overshoot is believed to be due, in part, to the presence of rolling friction and the inertial properties of the cart wheels. (JRH)

Presents activities to teach the concept of projectile motion to high school students using a spring-loaded dart gun, carbon paper, meterstick, ruler, white paper, tape, and a student's desk. (JRH)

Study of the nature of world view presuppositions held by (n=215) science teachers from 5 non-Western cultures shows that the subjects held identical world view presuppositions and suggests either poor conceptualizations of the nature of science or a form of collateral thinking. Contains 46 references. (Author/MKR)

Analyzes textbooks on thermodynamics with the aim of showing that several mental representations of this subject matter are present in scientific literature. Outlines divergent attitudes towards the definition of fundamental concepts and also towards the epistemological status of thermodynamics. Highlights the importance of historical…

Describes the extended general physics course taught at Rutgers University. The course presents to students at the high school algebra level the topic of analyzing a particular thought experiment that yields the time dilation formula and subsequently space contraction, velocity addition, and other 20th-century physics concepts.
