Anno XXXIX - n.1 - gennaio/marzo 2006 Miopia in età scolare e visione da vicino
This work considers the experimental evidence of the eye growth from visual signals. There is presented an eye model in which both the power of the lens and the distance lens-screen can be varied in order to show the accommodation and the elongation that the eye would become because of continual near vision. […]
Anno XLI - n.1 - gennaio/marzo 2008 Misura del momento d’inerzia di un libro
The relationship between the moment of inertia of a body and its period of twisting oscillation was studied in the classroom by suspending a book, in three different orientations according to its symmetry axes, to the edge of a table with a length of tape. […]
Anno XXVI - n.2 - aprile/giugno 1993 Misura dell’accelerazione di gravità con un semplice dispositivo on-line
This paper describes a measurement of the acceleration due to gravity done using a simple device connected to a computer on line. […]
Anno XXVII - n.1 - gennaio/marzo 1994 Misura della circonferenza terrestre col metodo di Eratostene.
This article describes an experiment done by first-year secondary school pupils, who measured me radius of the Earth with the method of Erathosthenes. For this purpose, cooperation was sought for and put into effect on long European distances, ranging from the island of Pantelleria in the Mediterranean to Goteborg in Sweden. […]
Anno XLVII - n.2 - aprile/giugno 2014 Misura della componente orizzontale del campo magnetico terrestre mediante una bilancia elettromagnetica costruita in casa
We report an experiment for measuring the horizontal component of the Earth’s magnetic field using easily available material, explaining how some conditions that optimize the results were obtained using a rectangular coil. […]
Anno XXXI - n.3 - luglio/settembre 1998 Misura della costante h/e (costante di Planck/carica elementare) mediante diodi L.E.D.
By means of some LEDs (Light Emitting Diodes) used as quasi-monochromatic light sources at different wavelengths and measuring their forward voltage at a fixed value of the current one can obtain the ratio of Planck’s constant to elementary charge with an estimated error of the order of 6%. […]
