Oyler, Michelle; Rivera, John; Roffol, Melanie; Gibson, David J.; Middleton, Beth A.; Mathis, Marilyn – American Biology Teacher, 1999
Presents a directed-inquiry activity to take students one step beyond observation of how living organisms capture prey. Uses a field lab based upon predator-prey relationships to enliven the teaching of food web concepts to non-science-major freshman undergraduates. Can also be used in teaching high school biology students through college science…

Edwards, T. H.; And Others – American Journal of Physics, 1975
Describes a laboratory experiment on geometrical optics designed for life science majors in a noncalculus introductory physics course. The thin lens equation is used by the students to calculate the focal length of the lens necessary to correct a myopic condition in an optical bench simulation of a human eye. (Author/MLH)

New York State Psychological Association, Inc., New York. – 1968
The purpose of this instructional unit is to convey an understanding of the part played by effective problem definition and hypothesis statement in the solution of scientific problems. The major concepts of the unit are process rather than content oriented. Problems, hypotheses, variables, constants and controls represent the principal concepts…
