Describes a computer program used to simulate Drosophila breeding and reproduction. The format of the program involved is presented as a part of the article. (PEB)

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)

Proposes method for determination of the pressure of a sphere by relating force and surface tension. (CP)

Describes the steps in writing a computer program to solve radioactive decay problems by a digital method. (CP)

Details approaches which may be used to present energy related topics to secondary school students. (CP)

Describes a series of experiments which illustrate the analytical capabilities of fluorescence, and outlines two straightforward analyses involving real analyses. These experiments are suitable for an undergraduate instrumental analysis course and require approximately six to seven hours of laboratory time. (MLH)

Describes a demonstration for showing the electrical activity in nerve and muscle including action potentials, refractory period of a nerve, and fatigue. Presents instructions for constructing an amplifier, electronic stimulator, and force transducer. (GS)

Describes a blindfold botanist project for high school biology students to augment visual recognition of plants and to serve as a challenge to motivate students. (BR)
