Presented is a short discussion of factors causing color changes in animals. Also described is an activity which may be used to demonstrate the response of amphibian skin to a melanophore stimulating hormone in high school or college biology classes. (PEB)

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)

Presents descriptions of three experimental procedures for physics classes: forced oscillations, measuring the refractive index of perspex, and measuring the critical potentials of helium. (SA)

Describes urinalysis techniques for dry weight measurement, examination of urinary calculi (stones), and determination of the presence of blood and blood pigments. Also presented are directions for preparing required reagents. (WB)

This second volume, a compilation of reprints of experimental notes in physics, was prepared by the American Association of Physics Teachers (AAPT) Committee on Apparatus and by the AAPT Executive Office in response to requests received by the Association for a completely new edition. The goal of the Committee was to provide a selection of…

The experiments in this manual represent state-of-the-art techniques which should be within the budgetary constraints of a college physics or chemistry department. There are fourteen experiments divided into five modules. The modules are on X-ray fluorescence, charged particle detection, neutron activation analysis, X-ray attenuation, and…

This guide is prepared for teachers who have students using the laboratory manual, "Laboratory Activities for Biology." The publication contains some introductory remarks for teachers, lists of materials and equipment, methods of making solutions and other preparations, suggestions for introductory discussions with the class, and…

Describes potentially dangerous classroom situations involving toxic minerals. The intent of the article is to make students aware of the dangers so that they may act responsibly in health-related decisions as professional geologists. (Author/SA)

Described are some experiments on geotropism that may be done using dandelions. (PB)

This book contains 65 physics experiments. The experiments are for a college-level physics course for music and art majors. The initial experiments are devoted to the general concept of vibration and cover vibrating strings, air columns, reflection, and interference. Later experiments explore light, color perception, cameras, mirrors and symmetry,…

This publication contains eighteen experiments and eight classroom activities. The experiments are of varying difficulty and cover the important aspects of solar energy utilization. Each experiment is self-contained, with its own introduction and background information. Energy measurements are emphasized and techniques for collector efficiency…
