The United States Training and Employment Service General Aptitude Test Battery (GATB), first published in 1947, has been included in a continuing program of research to validate the tests against success in many different occupations. The GATB consists of 12 tests which measure nine aptitudes: General Learning Ability; Verbal Aptitude; Numerical…

Providing opportunities for skill-building, creativity, and reading for content are major objectives of the "funny paper center." This multidisciplinary learning center uses comic strips as facilitators in the classroom. Suggestions are given for language arts, mathematics, science, social studies and art education. (Author/RK)

Lists 40 things to do to have a safer chemistry laboratory. Discusses the evolution of these guidelines for schools from safety suggestions originally developed by industry. Categorizes the 40 steps into those requiring minimal cost and those requiring moderate expense. (TW)

Discusses the properties of carbon dioxide in its solid "dry ice" stage. Suggests several demonstrations and experiments that use dry ice to illustrate Avogadro's Law, Boyle's Law, Kinetic-Molecular Theory, and the effects of dry ice in basic solution, in limewater, and in acetone. (TW)

Proposes that preparative chemistry is an important and integral part of chemistry as a whole, and an excellent way to introduce students to descriptive chemistry. Provides an outline for students to follow for converting and transforming salts. Suggests a set of general guidelines for studying anion and cation transformations. (TW)

Describes a chemistry experiment where an alkaline ice-cold permanganate solution is reduced by adding dropwise a cold diluted hydrogen peroxide solution. Outlines the course of the reduction through the various oxidation states of manganese with their characteristic colors. (TW)

Outlines an approach to chemistry experiments designed to help students appreciate the importance of each step in an experimental procedure. Describes an experiment involving Charles's Law to illustrate this idea. (TW)

Introduces the unique interfacing equipment for measuring muscle strength over time. Explains the materials, setup method, operation, and typical display. Suggests other activities with which to utilize this device. (YP)

Describes the procedures used to demonstrate transpiration with the common sunflower. Discusses the results expected from such an activity. Provided is a sample data sheet. (CW)

SCIENS is a Middlebury College (Vermont) program designed to excite minority student interest in the natural sciences and to provide students with training and research experiences. The program, encompassing three summers, involves core instruction for high-potential 11th-grade students, summer research in college laboratories, and internships in…

Explains gyroscopic motions to college freshman or high school seniors who have learned about centripetal acceleration and the transformations of a couple. Contains several figures showing the direction of forces and motion. (YP)

Demonstrates several objects rolling down a slope to explain the energy transition among potential energy, translational kinetic energy, and rotational kinetic energy. Contains a problem from Galileo's rolling ball experiment. (YP)

Describes a laboratory experiment designed for use in a freshman chemistry course. Considers the use of a set of known "training reactions" with a "training set" of solutions. (CW)

Explains how peer writing tutors not only help their fellow students, but can also learn a great deal themselves about grammar and mechanics, information processing, marking papers, audience awareness, and problem-solving strategies. (ARH)

Describes a simple redox reaction that occurs between potassium permanganate and oxalic acid that can be used to prepare an interesting disappearing ink for demonstrating kinetics for introductory chemistry. Discusses laboratory procedures and factors that influence disappearance times. (CW)
