Bennett, Jack – American Biology Teacher, 1980
Presents a scheme that illustrates the interdependence of proteins and nucleic acids in hereditary functions, built around the arguments and assertions on the nature and synthesis of nucleic acids and proteins presented in current texts. Provides background information in DNA synthesis, RNA synthesis, and a combined "hereditary system." (CS)

Adams, Clark E. – American Biology Teacher, 1983
Summarizes 19 literature sources identifying road-killed vertebrates and frequency of kill by numbers. Examples of how these animals can be incorporated into curricula (integrating biology, society, people, and values) are given, followed by an illustrated example of how a road-killed raccoon's skull demonstrated a human/wildlife interaction prior…

Thomson, James D. – American Biology Teacher, 1980
Presents a mechanical model for an ecology laboratory that introduces the concept of optimal foraging theory. Describes the physical model which includes a board studded with protruding machine bolts that simulate prey, and blindfolded students who simulate either generalist or specialist predator types. Discusses the theoretical model and data…
