Examines the estimates of known potential reserves of the major raw materials, future sources therof, the geological and technological problems associated with these, the manufacture of artifical minerals, and international cooperation in this sphere. (Author/GS)

Describes space-based observations and other aspects of meterology that will enable weather forecasters to lengthen the scale of predictability from the current day-to-day basis to one week or longer. (Author/GS)

Indicates that the current philosophy of laboratory experimentation and instrumentation is creating students that are not well versed in basic principles of chemistry. (GS)

Discusses the relation of technology to the green revolution, the role of plant breeders in inducing change in stagnant agriculture and the tools required by production scientists to increase yields of basic food crops in developing countries. (BR)

The purpose of the study was to examine science interest and attitude traits in students subsequent to the study of chemistry using the Nuffield Chemistry Program and revised non-Nuffield study schemes. The results indicated the present non-Nuffield courses favor the formation of positive science interest/attitude characteristics more strongly…
