Anno XXXVII - n.4 - ottobre/dicembre 2004 Caduta di un imbuto in un tubo d’acqua
In a school experiment the fall of a loaded plastic funnel in a long transparent cylindrical vessel full of water was measured and the experimental data were analysed. Based on the analysis of the data and of the experimental conditions, a law of the turbulent resistance of the medium was looked for and formulated. […]
Anno XXXI - n.1 - gennaio/marzo 1998 Campi, energia e lavoro. Motivazioni di una proposta
We enphasize here the educational reasons lying behind a reversal of the traditional approach to the introduction of work, energy, potential, and fields at high school level. The details of this approach have been fully described elsewhere. […]
Anno XXVI - n.2 - aprile/giugno 1993 Campo: concetto, misura, proprietà e conseguenze attraverso esperimenti quantitativi. 2° Premio: Liceo Scientifico M. Buonarroti – Monfalcone.
This paper describes the second prize-winning entry to 1991-1992 “Prernio Bonacini” contest for high-school boys on gravitational field. The 15 year-old students measured the gravitational constant, ascertaining quantitatively the proceeding of the gravitational field. […]
Anno XXVIII - n.1 - gennaio/marzo 1995 Capire la Time-Resolved Reflectivity: una tecnica di analisi basata sull’interferenza da lamina sottile
Thin film interference is the basis of Time-Resolved Reflectivity (TRR), a technique used in condensed matter physics to study phase transformations. Two series of simple experiments are proposed: one employing microwaves, and the other visible and infrared laser light. By the microwave experiments we show the role played by the thickness and the refraction index of the film. […]
Anno XXXVII - n.3 - luglio/settembre 2004 Capire le onde: Internet come risorsa?
Ways of using multimedia web-resources on wave behaviour, with the aim of integrating lectures, experimental activities and individual study are illustrated and discussed. The focus of the paper is on the advantage of using animations and simulations as tools that facilitate the cognitive path from observing real experiments to constructing physical interpretations and as collections of virtual situations allowing lab potentialities, […]
