This report details several simulated divinq experiments on the human. These are suitable for undergraduate or graduate laboratories in human or environmental physiology. The experiment demonstrates that a diving reflex is precipitated by both facial cooling and apnea. (Author/RE)

This elementary school science project involves making a car out of pegboard, spools, rubber bands, and dowel. (BB)

Describes procedures that students can follow to develop latent prints. An introduction of chemistry of latent prints is also presented. (HM)

Describes the use of 35 mm slides consisting of a diagram of photograph and 15 to 60 words of text to augment laboratory instruction. (GS)

Describes a system of laboratory instruction in which students attend laboratory when their schedules permit, and all laboratory sections, regardless of course, are overseen by one laboratory instructor. (MLH)

Describes methods and procedures for killing, preserving, mounting, and displaying insects. (JR)

Presents Latin square mathematical techniques for assigning laboratory partners so that each pair of individuals work together only once. (MLH)

This course presents the student with a performance approach to biology. Each technique is covered in standard lecture format and in guided, independent laboratories. Examinations and grading are competency-based and require knowledge of both the use and limitations of the techniques. (BB)

Describes procedures to demonstrate oxidation and simultaneous equilibria involving insoluble salts. (SL)

Outlines an approach for helping student teams assign roles to each participant for doing portions of the experiment and writing the report. Discusses teaching of technical report writing as outlined in the Style Manual of the American Institute of Physics. (MLH)

Discusses the vicious circle of perpetuating traditional practices in the use of laboratory organisms. Makes a plea for biology teachers to use new organisms for new tasks, indigenous organisms rather than imported ones, living organisms rather than dead, and organisms to explicate principles rather than as sources of stultifying detail.
