The author describes a model for operations on the set of rationals. Thi s model, used by students in a laboratory situation, is based on an easily constructed number balance. (SD)

A pair of experiments, appropriate for the lower division fourth semester calculus or differential equations course, are presented. The second order differential equation representing the equation of motion of a simple pendulum is derived. The period of oscillation for a particular pendulum can be predicted from the solution to this equation. As a…

This reference guide contains laws, regulations, and licensing requirements and procedures governing chiropractic practice in New York State. Following a general introduction to professional regulation in New York State, licensure requirements are spelled out in detail, including general requirements, education requirements, examination…

Biological waste treatment in the activated sludge process is based on the ability of microorganisms to use dissolved oxygen in breaking down soluble organic substances. The oxygen uptake test is a means of measuring the respiration rate of microorganisms in this process. Designed for individuals who have completed National Pollutant Discharge…

Describes a number of activities designed to assist student understanding of the phenomenon of light bending when it passes from one meduim to another. (JR)

Describes the sturcture and asexual reproduction of the fungus Pilobolus and outlines a number of experiments with this organism that are suitable for secondary school biology students. (JR)

Discusses an experiment on friction to illustrate the "law" governing the relationship of the friction force to the volocity of air track cars. (CC)

This bulletin describes a procedure to provide graduate students with meaningful lab experiences, and to integrate the study of a variety of group counseling approaches with actual group leadership opportunities. It allows the beginning group counselor to develop confidence before working with emotionally disturbed clients, and also provides…

This document presents a series of physics experiments which allow students to determine the value of unknown electrical capacitors. The exercises include both parallel and series connected capacitors. (SL)

Describes a computer program which permits students to check their calculations while they are still in the laboratory by entering their raw data and calculated results via a teletype terminal situated in the lab. The input is examined and the student is informed of the nature of each error. (MLH)

Describes an arrangement of a laboratory course in biochemistry designed to teach currently used biochemical techniques and then have students apply the procedures in a real research program so as to give students a better understanding of biochemistry. (BR)
