Anno XXV - n.4 - ottobre/dicembre 1992 LA FISICA DEGLI ORDINI DI GRANDEZZA
Riflettere alla svelta! L’arte di stimare (parte seconda)
(Traduzione da Quantum, marzo-aprile 1991, a cura di C. Marchi Trevisi)
This article is an example of the physics activities for interested youngsters offered by the journals KVANT and QUANTUM. It contains a series of unusual solved problems, appropriate for high-school students, the solution of which requires making order-of-magnitude estimations. […]
Anno XXV - n.4 - ottobre/dicembre 1992 Un semplice esperimento di carattere frattale
By making paper balls with crumpled sheets of paper and studying the functional relationship between their mean diameters versus their mass it is possible to introduce the concept of fractional dimensions to students. […]
Anno XXV - n.4 - ottobre/dicembre 1992 Il pendolo… in acqua
Following the pupils’ suggestions and curiosity it is sometimes possible to remove some of their preconceptions. […]
Anno XXV - n.4 - ottobre/dicembre 1992 Flusso laminare di un fluido intorno ad un corpo sferico. (Traduzione da School Science Review, vol. 71, n. 257,a cura di Silvia Pugliese Jona)
A simple experiment to demonstrate streamline flow around a sphere falling at terminal velocity in a viscous fluid. […]
Anno XXV - n.3 - luglio/settembre 1992 Venti anni di effetto fotoelettrico (1887-1905)
After a concise description of the experimental aspects of the photoelectric effect, this article gives an account of me history of its discovery and of the research that followed, and discusses its contribution to the radical changes in the conceptual framework of physics from the last decade of the past century to Einstein’s work of 1905. […]
Anno XXV - n.3 - luglio/settembre 1992 Una visione critica dell’attività pratica nell’insegnamento delle scienze sperimentali.
The article takes a critical look at practical work in school science and the often extravagant claims that we make for it. In asserting that much of what we do is ill-conceived, muddled and of little educational value, a case is made for a more rigorous, […]
Anno XXV - n.3 - luglio/settembre 1992 La metrologia verso l’unificazione europea del 1993
Since 1971 EEC is giving indications to the member States on the adoption of increasingly unified metric units, to which each State responded by promulgating appropriate laws. After a short history of the S.I., this article comments on the Italian laws and the public perception of the problem and gives information about the penalties and risks connected with using the improper units. […]
Anno XXV - n.3 - luglio/settembre 1992 Diagnosi della comprensione di velocità media utilizzando un modulo tutoriale computerizzato
This paper describes the construction of a computer-based diagnostic module on the comprehension of the concept of average velocity. In the module, different kinds of mistakes are referred to a model of the users’ possible reasoning patterns. Accordingly the users are lead along different paths. […]
Anno XXV - n.3 - luglio/settembre 1992 La respirazione: una esperienza didattica di Educazione Sanitaria e di Laboratorio di Fisica nella scuola dell’obbligo
The activities described in this article were carried out with a group of 17 12-year-old Middle School pupils. The project involved the Science Lab, the Gym and the Music Class. The pupils performed experiments using simple apparatus they built themselves and enhanced their ability to express themselves in music (playing the flute) and song. […]
