An introductory biophysics course for science students who have previously taken two quarters of noncalculus physics is described. Material covered emphasizes the physical principles of sound, light, electricity, energy, and information. (Author/CP)

The authors give directions for comparing the rates of zero and first order chemical reactions to the rate of flowing water in simple physical systems. They also show how to compare chemical equilibrium to the level of water in a u-shaped tube. (AJ)

Describes a method of calculating the power applied to an electric lamp by using a calorimeter to measure the energy radiated by the lamp. (SL)

Discusses four different methods for measuring self-inductance based on the definition of inductance, the alternative definition, phase difference and LC resonance. Provides circuit diagrams and typical oscilloscope traces. (YP)

Describes experiments used during recent history to explain the nature of the quantum world. Explains the essential elements of experiments using polarized light and magnetic flux. Illustrates differences between classical theories in physics and quantum theory. Shows how experiments in the microscopic and macroscopic world appear to support…

Describes a simple method for measuring respiration, net photosynthesis, and compensation points of plants in relation to light intensity. Outlines how the method can be used in teaching physiological adaptation. Includes a set of the experiment's results. (ML)

Argues that computer-simulated experiments offer educational tools to foster student development of problem-solving skills without traditional laboratory time and expense. The evolution of the medical physiology course at Rush Medical College is used to illustrate trends in this area. They include experiments on PLATO, and on personal computers.…
