Describes a method utilized at Iowa State University for teaching a biochemistry laboratory course for non-majors involving the use of student independent projects and experimental choices. (BT)

The role of technology throughout history and its relationship to science is discussed. The new frontier of societal technology is considered in terms of human behavior and misbehavior in the face of conflict. (SA)

The experiments described in this article discuss the versatility of the linear variation method in quantum chemistry and the ease with which it can be used with a simple computer program. (SA)

This is an experiment for college chemistry students in which they are introduced to gas phase and aerosal analysis and the chemical nature of cigarette smoke and its health hazards. (Author/SA)

Some universities and technical schools in the United Kingdom have established a new discipline of environmental science usually rooted in, but distinct from ecology, geology, and planning. The article describes such a program at the New University of Ulster. (Author/SA)

Describes laboratory experiments of a chemistry course on advanced process control. The equipment for the process around which these experiments were developed by the University of Louisville was constructed from data provided by Exxon Oil Company. (HM)

Investigates some conceptual difficulties which college students have with regard to simple direct current circuits. The clinical interview technique was used with 57 students in a freshman level engineering course. (HM)

Discusses the increasing role of the physicist in plastics technology. Relationships of molecular structure to material behavior, design which is related to the material, and the practical problems of fabricating a material into an article are included. (HM)

Describes a resonance apparatus for the measurement of Cp/Cv for different gases. In the apparatus a magnetically supported piston in a vertical cylindrical glass tube containing the gas is forced into oscillation by means of a standard audio signal generator. (Author/GA)

Investigated is the period of a simple pendulum. The cases of the rigid rod and fexible cord are reviewed. By applying a variational principle it is proven that the first order correction to the period is the same for both the cord and the rod. (GA)

Describes a system of small electronic modules suitable to teach digital electronics, construct digital systems for the instrumentation of standard experiments, or, teach analog electronics. Explains both the design of the modules, and some of the instructional uses of the system. (GA)

Describes simple modifications that will permit external triggering of certain electronic timers, thus allowing their use in experiments which require greater precision than was possible with inexpensive apparatus. (GA)

Discusses how the nature of the rock and, particularly, its fossils can be used in ecology courses for schools and colleges to help students to deduce the nature of the environment at the time the rock was deposited. A checklist and ways of identifying geological sites and fossils are included. (HM)

Describes, using "nonorthogonal" displacement functions, the normal-mode motions of a massive particle and a spring of non-negligible mass to whose end the particle is attached. The results lead to the complete solution for the general motion of the spring-plus-particle system. Shows that the presence/absence of gravity is irrelevant to the…

Describes a simple experiment for measuring the speed of sound using a partially filled beer bottle as a resonator. Outlines and discusses the approximations made in arriving at the procedure. (GA)
