Direct linkPedrosa, Cristiana; Mendes, Joaquim; Magalhaes, Fernao D. – Chemical Engineering Education, 2006
A low-cost tensile testing machine was built for testing polymeric films. This apparatus also allows for tear-strength and flexural tests. The experimental results, obtained from common-use materials, selected by the students, such as plastic bags, illustrate important aspects of the mechanical behavior of polymeric materials. Some of the tests…

Nellis, Margaret J.; And Others – 1982
The role of environmental stimuli in the control of cigarette smoking has been the object of theoretical speculation, but there have been few experimental demonstrations of the control exerted over smoking by environmental events. Self-report data on smoking in the natural environment were compared to observations made of smoking among subjects…

American Psychological Association, Washington, DC. – 1983
These guidelines are intended to assist high school psychology teachers in safeguarding the rights and welfare of students and experimental subjects while promoting high-quality instruction. There are three sets of guidelines. The first set deals with the use of animals in school science behavior projects. The major goal of such projects should be…
