Describes major programs carried out by the National Bureau of Standards to solve problems relating to energy resources, technological innovation, public health protection and unit standardization. (CC)

Several ideas are proposed for chemistry teachers to try in their classrooms. Subjects included are polymerization of acrylate, polymerization of styrene, conductivity, pollution, preparation of chlorine, redox equations, chemiluminescence, and molecular sieves. (PS)

Ideas are proposed for physics teachers to use in their classrooms. Subjects include: alpha particles, spectrometer experiments, refractive index of glass, measurement of surface tension, projectile motion, and radiant heat. (PS)

Includes a simple technique to demonstrate Millikan's oil drop experiment, an environmental studies experiment to measure dissolved oxygen in water samples, and a technique to demonstrate action-reaction. Science materials described are the Pol-A-Star Tomiscope, Nuffield chemistry film loops, air pucks and pH meters. (JR)

Outlines a laboratory course entitled Inorganic Chemistry for Biological Sciences'' which is designed primarily for juniors in biochemistry, physiology, and soil sciences. Inclusion of relevant environmental topics is indicated. (CC)

Summarizes the thermodynamics of macromolecular systems, including theories and experiments of cyclic energy conversion with rubber and collagen as working substances. Indicates that an early introduction into the concept of chemical potential and solution thermodynamics is made possible through the study of the cyclic processes. (CC)

Discusses an open-ended experiment which is instigated by students to study noise levels on the Kent State University campus. Indicates that the activities make it possible for the students to acquire socially relevant and potentially useful information under more realistic environments. (CC)

Discusses various ways established by the Task Group on Education in Astronomy, including publication of teaching resources and lists of speakers for teachers' meetings at all levels and of writers of articles for teachers' journals. (CC)

Discusses the use of a balance assembled from standard laboratory components to conduct an experiment on the repulsion between two bar magnets. Includes an analysis of data on the two-pole and four-pole models. (CC)

Describes some laboratory experiments that can strengthen the study of non-aqueous ionizing solvents in Nuffield A-level chemistry course. (PS)
