Described is a cardiovascular simulator which illustrates the use of a catheter-coupled external transducer for dynamic pressure measurements in the circulatory system. With the simulator, students can observe the effects of stroke volume and rate upon maximum, minimum, and mean arterial pressure. (Author/GA)

Secondary school students' attitudes toward science or the sciences were determined with specially constructed scales and from records relating to student enrollment in science courses. Emphasis is placed on factors which influence girls to enroll in physical science courses vs biological science courses. (SA)

Presents descriptions of three experimental procedures for physics classes: forced oscillations, measuring the refractive index of perspex, and measuring the critical potentials of helium. (SA)

Presents five selected physics activities which could be used in school physics courses. (HM)

Lists the obsolete, unnecessary, and misleading terms that occur within biology, chemistry, and physics literature. The terms selected are those most likely to be found in common use. Lists are also included of terms that teachers may need for introductory courses. (Author/SA)

A judge for the physics projects for the 1979 International Science and Engineering Fair describes many of the more popular science projects. Projects described include the following: carbon dioxide and helium-neon lasers, reverse flame investigations, holography, construction of a magnetic bottle to confine plasma, and aerodynamic drag. (BT)

Discusses the cognitive outcomes of physics laboratory exercises and suggests three types of experiments which should be added to those normally used in physics courses. (HM)

Describes a physics laboratory for college students, in which the students participate in a firsthand noninertial experience. The equipment and problems are described. (SA)

Describes few heat demonstrations where the use of a coolant spray could enhance their effectiveness. (GA)

Describes the structure of a physics course organized into independent-learning modules and designed to make use of the facilities of a Computer Assisted Management of Learning (CAMOL) package. (GA)

Describes: how to measure index of refraction by the thickness method; how to teach the concept of torque using a torque wrench; how to produce a real image with a concave mirror; how to eliminate the interface effects of a Pyrex containers; and an apparatus to illustrate Bernoulli's Principle. (MLH)

Discusses some misleading statements found in elementary and secondary science materials concerning electricity and magnetism. (MLH)

Discusses the laboratory portion of a beginning noncalculus physics course that uses concrete examples of abstract concepts. Describes the use of coffee cans to explain oscillations and plastic darts to illustrate collisions. (MLH)

Presents a study that analyzes an extensive database consisting of the written and oral discourse of students (N=23) as they described their thoughts on ontology, epistemology, and sociology of scientific knowledge. Contains 51 references. (DDR)

Discusses circuits for three-bit and four-bit analogue digital converters and digital analogue converters. These circuits feature slow operating speeds that enable the circuitry to be used to demonstrate the mode of operation using oscilloscopes and signal generators. (DDR)
