Discusses who has the right to determine the use of animals in scientific research which includes medical experimentation and the toxicity testing of compounds, ranging from pesticides to cosmetics. Provides a list of questions for consideration and discussion. (RT)

Demonstrates a laboratory to teach the concept of moment of inertia in which students are asked to identify four objects of equal mass sealed in unopenable containers by identifying the mass distribution of each object. Gives instructions to build an instrument to determine relative distribution of mass. (MDH)

Describes school science as a rite of passage, and exposes problems in school science that are made visible through the use of this metaphor. (PR)

This paper provides an exposition on simple and complex comparisons within the framework of Poisson regression. Poisson regression is well suited for the analysis of event count outcomes. Since simple and complex comparisons with both analysis of variance (ANOVA) and multiple linear regression (MLR) are common, the similarities between Poisson…

The effectiveness of science experiments often are partly dependent upon the amount of classroom time available for implementation. This factor alone has frustrated many teachers who attempt to complete laboratory assignments in the allotted time period. This document provides experiments that were designed for the middle year in a 3-year biology…

This book contains simple experiments through which students can learn about the properties of energy. These experiments include making a kitchen "volcano," a soda-pop "cannon," and a puffed-rice "scooter." Topics include: energy and work, fossil fuels, solar energy, kinetic energy, potential energy, mechanical energy, heat energy, sound energy,…

Twelve desk-top experiments and demonstrations which illustrate properties of and facts about gas are presented. Each experiment includes: purpose, materials needed, instructions, and a list of facts and properties that have been observed. Several of the activities also include questions for students and items for discussion. The topics of the…

A look at an experiment in which three pilot inquiries relating to non-traditional instructional media "treatments" evidenced only one difference--roommate impact--having statistically significant differences associated with learning as reflected in earned, college-level grade-point averages. (Author)

Describes in detail the laboratory procedure for studying the process of amitosis in the vegetative cells of Nitella axillaris. (BR)

Article concentrated on an experiment in multidisciplinary and intercultural research cooperation which involved the building up of the national law of Indonesia. (Author/RK)

A group of art students at Belleville Township (Illinois) High School West recently discovered what important roles well-trained senses of touch and muscle movement play. (Author)

The experiment described is an excellent opportunity to apply theoretical concepts of distillation, thermodynamics of mixtures and process simulation at laboratory scale, and simultaneously enhance the ability of students to operate, control and monitor complex units.

On December 2, 1942, in a racquet court underneath the West Stands of Stagg Field at the University of Chicago, a team of scientists led by Enrico Fermi created the first controlled, self-sustaining nuclear chain reaction. This updated and revised story of the first reactor (or "pile") is based on postwar interviews (as told to Corbin…
