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…

Infant reaction to adult speech was studied through frame-by-frame analysis of sound films. Infants' actions were found to be synchronized with the organized speech behavior of the adults in his environment. (ST)

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 a student project which is intended to teach undergraduates concepts and techniques of nuclear physics, experimental methods used in particle detection, and provide experience in a functioning research environment. Included are detailed procedures for carrying out the project. (CC)

Presents some examples of using college, university, industrial, and governmental raw data to conduct physics classroom experiments and activities. Indicates that the approach has the advantages of making the student work publishable and of motivating the student to improve the quality of lab reports. (CC)

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 document provides abstracts of 116 laboratory experiments/demonstrations currently being utilized in all areas of engineering education at 52 universities across the United States. (SL)

Describes an experiment designed to acquaint the chemistry student with polymerization reactions, vacuum techniques, liquid scintillation counting, gas-liquid chromatography, and the handling of radioactive materials. (MLH)

Describes an experiment in which luminescence is observed during a reaction between sodium borohydride and trisbipyridalruthenium (III). Includes a discussion of the theory of chemiluminescence. (MLH)

Suggests replacing traditional organic chemistry laboratory exercises with experiments involving an elementary research approach. The student is provided with short laboratory projects, normally involving simple reactants and products; it is an important criterion that the reactions chosen are not normally featured in student textbooks. (MLH)

Describes an experiment in which possible products of a series of reactions are tabulated together with properties which may be useful in identifying each substance. The student deduces the products and writes a balanced chemical equation for the reaction. (GS)

Describes an experiment which monitors the population of the lowest triplet state by directly observing phosphorescence intensity as a function of time. Reviews the theory concerning triplet state lifetimes, describes the experimental apparatus and procedure, and presents the method and examples of data analysis. (GS)
