Describes procedures to develop instructional objectives for high school biology. Two kinds of objectives are identified as pre-objectives and performance objectives. Models to classify these in branches of biology and to ensure quality control are provided. (PS)

The question of attributing a purpose to animal's actions is still being debated by scientists. Consensus seems to be that animal behavior should be described in terms of function rather than purpose. (PS)

The author discusses a system for establishing the relative potential of a chemical to release energy suddenly and to indicate release. This system is applicable to chemical storage and transportation. The system is based upon three simple tests requiring a minimum sample (1 go or 1 ml): (1) computation, (2) impact sensitivity, and (3) thermal…

Compares the cost, in terms of thermodynamic potential, of manufacturing automobiles from raw mineral resources or from recycled vehicles, and of the production of extended-life products. Uses this as an example for arguing that new technologies, with efficiencies closer to the theoretical themodynamic minima, are needed if a society is to…

Historical interpretation is a primary responsibility of the historian in addition to discovery of the factual past. Using historiographical study as one aspect of historical study, a teacher provides a vehicle for understanding and gaining experience in the use of the reflective process. (JB)

Recognizes that physics, like other sciences, deals with information in the form of sense impressions. Concepts of mass length and time are not sensory experiences and should substitute instead the terms of force, displacement and time for better understanding. (PS)

Describes how four independent puzzles in nuclear physics converge in a single, unifying explanation--some nuclei can exist in two different shapes." (Author/TS)

Reviews ideas and evidence bearing on the origin of life. Shows that evidence to support modifications of Oparin's theories of the origin of biological constituents from inorganic materials is accumulating, and that the necessary components are readily obtained from the simple gases found in the universe. (AL)

Cites examples of the contribution of basic research in evolutionary biology to the solution of problems facing society (1) by dispelling myths about human origins, the nature of the individual, and the nature of race (2) by providing basic data concerning the effects of overpopulation, the production of improved sources of food, resistance of…

Advocates the use of sidepacks and backpacks for field studies and lists accompanying equipment. (CP)
