The aim of this paper is to show how the noise reduction by signal accumulation can be accomplished with a data acquisition system. This topic can be used for student projects. In many cases, the noise reduction is an unavoidable part of experimentation. Several techniques are known for this purpose, and among them the signal accumulation is the…

Sarah Screech, Danny Decibel, Sweetie Sound and Neil Noisy describe their experiences in the world of sound and noise to elementary students. Presented are their reports, games and charts which address sound measurement, the effects of noise on people, methods of noise control, and related areas. The workbook is intended to stimulate students'…

The "Science Related to Life" textbooks are written to supply the need of elementary science teachers with textbooks that can be used independently by pupils. Throughout the series the author has kept in mind the aims of elementary science, as recognized by modern courses of study, namely to develop in pupils an interest in the natural…

Part of a series on Arapaho Language, the student workbook introduces sounds and their relationship to language learning. The workbook presents explanations of sounds made by mammals, birds, and amphibians; vibrations made by vocal cords; the use of the tongue or shape of the mouth to make sounds; and human speech sounds. Exercises in speech and…

While the new movement in the teaching of physics--the study of the physics of daily life--is the keynote of the recent text-books, yet the laboratory manuals still adhere to the old method, leaving the presentation of material from everyday life to the text-book alone. It is the authors' belief that the manual as well as the text-book should be…
