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)

A description of the film loop laboratory system as an attempt to increase the desirability, flexibility, and efficiency of physics experiments for non-science students. (Author)

Includes thirteen topics relating to laboratory activities, organisms, and teaching materials for secondary school biology classes. Also provides a reading list of articles published during 1972 that are suitable for A and S level biology. (JR)

Describes the measurement of electric potentials by means of a flame probe. This method is used extensively in the new Nuffield Advanced Level Physics course, and provides a means of taking reliable quantitative results in an area of most school courses where the majority of the work is qualitative.
