Describes how to assemble a respirometer from common laboratory materials for quantitative measurements of gas production. (LS)

Describes a variety of classroom aids and indicates the sources. Included are storage facilities, sound experiments, stop watch, ultraviolet lamp, calculators, animal cages, and others. (RH)

Discusses the eleven-year sunspot cycle and its effect on the temperature and precipitation in the world's weather zones. (MLH)

Describes the science activities at a school camp located in the San Bernadino mountains. Each sixth-grade student in the Long Beach, California school district attends this camp for one week. (MLH)

Discusses the use of future-oriented science curricula as a means of promoting scientific literacy. (MLH)

Gives basic instructions for rearing several readily available insect species particularly well suited to use in secondary, and even elementary, school classrooms and laboratories. (LS)

Presents a simple model which may be used to estimate the seasonal abundance of an insect species, which fluctuates from year to year. (LS)

Suggests the use of simulations, games, and case studies to make chemistry more appealing and interesting to secondary level students who range greatly in motivation and aptitude. (MLH)

A high school biology experiment is presented. The success of this experiment may be due to the inability to prove or disprove the hypothesis upon which it is based. (BB)

Investigates a method to predict best and least suited students for the ISCS instructional approach. Aptitude-treatment interactions associated with ISCS instruction and a set of aptitude, attitude, and skill factors were utilized to make and verify predictions on two dependent variables--achievement and success. (Author/GA)

A discussion of problems students have with the concept of percent, with special emphasis on the use of percent in elementary chemistry. (BB)

Describes the development and the composition of birth control pills. Explains the way the pill works, and other methods of contraception. (GA)

Tries to clarify some apparent confusion surrounding the concept of atomic weights as presented in some chemistry textbooks. Another confusion is with the word thermometer, as it implies heat measurement. Suggests renaming it calorikinetic potentiometer, instead, to reflect what it does. (GA)

Describes how the students of physics and drama have cooperated in an interdisciplinary project to produce a play, "The Physicists," in a high school. The purpose of the play is to promote artistic and analytical thinking. (GA)
