Describes a freshman level physics laboratory course which includes elements of mathematical statistics. (SL)

Describes physics laboratory equipment including: circuit improvements for an electronic counter-timer, a commercial counter-timer-frequency meter, and a device for demonstrating resonating air columns. (SL)

Describes a class of ion-selective electrodes that use a solid-state sensing membrane. These are suitable for student activities. (SL)

Presents a method of teaching advanced physics laboratories which simulates research conditions and requires students to make researchlike decisions. (SL)

Describes the inception, use, and evaluation of a demonstration laboratory designed to enable first-year university students to observe physical phenomena that they did not observe in the secondary school. (Author/SL)

Discusses the improvement of safety and health conditions in academic chemistry laboratories. Included are 14 recommendations for improving laboratory safety. (SL)

Argues that using outdoor classrooms to examine environmental studies will help heighten the student's awareness of the importance of protecting our environment. Describes how such a land laboratory could be developed. (RKM)

Described is a series of five related microcomputer-based laboratory analysis programs that are used by students in a college calculus-based physics course. With minor modifications these programs, which are written in BASIC, could be used in most beginning undergraduate laboratory science courses. (RH)

Offers suggestions and outlines ten easy steps for assuring a safer science classroom environment. Includes such recommendations as: scheduling a safety inspection; displaying safety posters; enforcing a laboratory dress code; establishing a safety reference library; and updating safety report forms and procedures. (ML)

Examines factors affecting attitudes toward laboratory chemistry. Subjects (N=1638) were grade 11 chemistry students in 78 schools in rural, suburban, and urban Oyo State, Nigeria. Data indicate that students' attitudes toward chemistry as a subject is the most important determinant of the attitude toward the laboratory. (JM)

Describes a computer program (for the IBM microcomputer) which simulates pulsatile events in the heart in time frames that approach the speed of physiological events. The program also simulates the experimental laboratory in which the mechanics of an isolated heart can be studied. (Author/JN)

Examines some of the considerations involved in setting up a typical oxygen/organic reaction. These considerations (including protection for personnel/equipment, adequate ventilation, reactor design, maximum reactor charge, operating procedures, and others) influence how the reaction is to be conducted and what compromises the scientist must…

A model elementary science program was established through cooperation of Washington, DC, schools and the National Science Teachers Association. The program is expected to be a model for techniques and strategies adaptable to other schools. Program content, instructional purposes, and the fully equipped laboratory used are discussed. (DH)

Part I of this paper (SE 538 295) described a simple model for estimating laboratory concentrations of gas phase pollutants. In this part, the measurement of ventilation rates and applications of the model are discussed. The model can provide a useful starting point in planning for safer instructional laboratories. (JN)

Provides information related to the design of chemistry classrooms and laboratories. Project cost estimates, space assignment by function, generation of space requirements, educational specifications, and space conversion formulas (considering net assignable square feet) are among the topics discussed.
