When an odor is paired with a delayed illness, rats acquire a relatively weak odor aversion. In contrast, rats develop a strong aversion to an olfactory cue paired with delayed illness if it is presented simultaneously with a gustatory cue. Such a conditioning effect has been referred to as taste-potentiated odor aversion learning (TPOA). TPOA is…

Most, if not all, industrial technology (IT) programs have laboratories or workshops. Often equipped with modern equipment, tools, materials, and measurement and test instruments, these facilities constitute a major investment for IT programs. Improper use or over use of program facilities may result in dirty lab equipment, lost or damaged tools,…

Web-based computer-aided instruction (CAI) has become increasingly important to medical curricula. This multi-year study investigated the effectiveness of CAI and the factors affecting level of individual use. Three CAI were tested that differed in specificity of applicability to the curriculum and in the level of student interaction with the CAI.…

This packet attempts to provide educationally sound alternatives to dissection in the classroom, thereby making it possible for teachers to eliminate dissection from the curriculum. This packet can also be used by educators who include dissection in their curricula but consider it important to respect the expression of students' ethical, moral, or…

Primary students can use a geoboard to develop perceptual motor skills, pattern observation, and thinking ability by reproducing designs and developing strategies for games. (SD)

Too often science seems to be a matter of studying from books and responding to questions raised by teachers about the information either in the classroom or on examinations. Such a view of science misses its importance as a way of thinking, doing, and preparing for citizenship roles. The problems and activities included in this volume are…

This resource guide provides information for 13 laboratory experiments designed to be conducted in small schools with limited equipment and materials. For each experiment, the document outlines necessary equipment and materials, experiment procedures, and questions to be answered. The experiments are: (1) studying the properties of water; (2)…

This book is an outlined for the short study (1- to 2-weeks) of chronobiology, a field of science that explores the relationships between time and biological functions. It develops step-by-step the reasoning that leads to the current scientific understanding of biological rhythms. The unit can be inserted into a standard middle or high school…

Science and technology affect every facet of human life. By the 21st century, society will demand that all of its citizens possess basic competencies in the fundamentals of science and the use of technology. As science increasingly becomes the dominant subject of the work place, it is important to begin developing within children an understanding…

This document is the second edition of the Annotated List of Laboratory Experiments in Chemistry first published in 1980. All entries in the Journal of Chemical Education describing laboratory experiments in chemistry or laboratory descriptions suitable for student experiments or projects, for the years 1957-1984 inclusive, have been listed and…

The purpose of this water treatment field study training program is to: (1) develop new qualified water treatment plant operators; (2) expand the abilities of existing operators, permitting better service both to employers and public; and (3) prepare operators for civil service and certification examinations (examinations administered by…

The purpose of this wastewater treatment field study training program is to: (1) develop new qualified wastewater treatment plant operators; (2) expand the abilities of existing operators, permitting better service both to employers and public; and (3) prepare operators for civil service and certification examinations (examinations administered by…

During a time when the values in society are changing, knowledge is rapidly expanding, technology is changing, and the use of science and technology is increasing, there is a need to review the role and nature of a biology program for the schools. Such a review was conducted by the K-12 Science Working Party of the Manitoba Department of…
