So-called "Color Wonder" markers contain colorless dyes that only display color when used to mark on special "Color Wonder" paper. These markers make use of leuco dyes that only develop color in the presence of acid. These markers provide science educators with a novel chemical system that can be implemented in inquiry-based…

The work describes an analogy-based small oscillations analysis of a standard static equilibrium lab problem. In addition to force analysis, a potential energy function for the system is developed, and by drawing out mathematical similarities to the simple harmonic oscillator, we are able to describe (and experimentally verify) the period of small…

A recent note in this journal presented a demonstration of standing waves along a cord consisting of two parts having different material densities, showing different sized wavelengths in each part. A generalization of that experiment to a continuously varying linear mass density is to vibrate a strip of material with gradually varying width (mass…

Special events like science days, teacher's meetings and physics recruiting efforts require spectacular and, if possible, interactive experiments for the audience. Based on past experience with such events, we have gathered and present here a series of demonstration experiments in mechanics, optics, waves and electricity which are suitable, and…

This booklet of experiments was compiled from various teachers' guides in response to the many requests from students for help in preparing smoking demonstrations and exhibits. The booklet is divided into three sections. Part 1 illustrates a number of experiments, most of which require some laboratory equipment. Part 2 includes a number of…

A chemical demonstration book project was described. (BB)

"Females in Engineering, Methods, Motivation, and Experience" (FEMME) is a precollege program at New Jersey Institute of Technology giving academically talented ninth-grade girls an introduction to engineering. Four experiments (windmill building, burglar alarm construction, electrochemistry, and spatial reasoning activities) helpful in achieving…

AN ATTEMPT WAS MADE TO ASCERTAIN WHETHER MOTION PICTURE FILMS OF SELECTED PHYSICS DEMONSTRATION EXPERIMENTS WERE AS EFFECTIVE AS DEMONSTRATIONS PERFORMED DURING COLLEGE PHYSICS LECTURES. A SECOND OBJECTIVE WAS TO DETERMINE WHETHER STUDENTS WOULD TAKE ADVANTAGE OF THE OPPORTUNITY TO VIEW SOME EXPERIMENTS ON FILM OUTSIDE OF CLASS ON A VOLUNTARY…

Highlights the need to make the undergraduate physics laboratory more exciting and commensurate with the time assigned for it in the curriculum. Suggests establishing a model undergraduate physics laboratory at one place then reproducing it in five places for a massive reorientation program for teachers. Contains brief outlines of 30 experiments…

Describes a project to improve the science curricula and the science teaching skills of instructors in Houston-area two-year colleges in such a way that the program can be replicated in other locations. Two-year college faculty members were teamed with faculty from universities. (PR)

INCLUDED IN THIS MANUAL WRITTEN FOR SECONDARY SCHOOL AND COLLEGE TEACHERS ARE DESCRIPTIONS OF DEMONSTRATION MODELS, EXPERIMENTS PERTAINING TO SOME OF THE FUNDAMENTAL AND APPLIED METEOROLOGICAL CONCEPTS, AND INSTRUCTIONS FOR MAKING SIMPLE WEATHER OBSERVATIONS. THE CRITERIA FOR SELECTION OF TOPICS WERE EASE AND COST OF CONSTRUCTING APPARATUS AS WELL…

Explains the importance of introductory science courses and presents characteristics of exemplary courses. (PR)

This document was compiled to help keep science and mathematics teachers in Australia abreast of the results of important research endeavors in education. The monograph is divided into 12 chapters. Chapter one, "Exemplary Science and Mathematics Teachers," (Barry Fraser and Kenneth Tobin) describes a study focusing on examples of…
