Anno XXVI - n.1 - gennaio/marzo 1993 Polarizzazione della luce e legge di Malus
This article describes an experiment on Malus’ Law for polarized light, using a LED as light source, two polaroid sheets as polarizers and a phototransistor as receiver. […]
Anno XXXI - n.4 - ottobre/dicembre 1998 Quantizzazione della conduttanza in contatti d’oro unidimensionali
Using a very easy experiment, conductivity quantization can be observed. In this way quantum mechanics becomes something students can also experiment. […]
Anno XLIII - n.4 - ottobre/dicembre 2010 Riga da disegno usata come bilancia a pendolo
An experimental exercise on using a pendulum for measuring masses, proposed to the Italian students enrolled in one of the national sessions of the Physics Olympiads, is described and discussed. […]
Anno XXVII - n.1 - gennaio/marzo 1994 Simulazione della disintegrazione radioattiva con il lancio dei dadi.
14 and 15 year old students study the law of exponential decay using an experimental approach, which leads them to perceive analogies and differences between many natural phenomena. […]
Anno XXIII - n.3 - luglio/settembre 1990 Sperimentare a lezione. Schede di esperienze didattiche
The use of demonstration experiments during physics lectures is a powerful help for both teacher and students. We suggest that records be preserved with detailed description of materials and methods. A collection of cards, each presenting a single experiment, is being prepared; […]
Anno XLIV - n.4 - ottobre/dicembre 2011 Sperimentare fisica: l’esperimento di Millikan
An experimental activity designed to repeat Millikan’s measurement of the elementary electric charge was performed in a high school. Using a lab instrument, similar in principle to Millikan’s, we look for the quantization property of electric charge we try to estimate its value. […]
Anno XLIV - n.3 - luglio/settembre 2011 Suono a scuola e suono a casa
We suggest a simple experimental method to let the students understand the Physics of the sound. The method can be carried out at school, but also as homework, provided that students have a PC and some other easily available items such as tuning forks, […]
Anno XXVI - n.4 - ottobre/dicembre 1993 Svuotamento di un serbatoio d’acqua attraverso un tubo capillare
The article describes a simple experiment to illustrate the exponential decay of a water column. The liquid flows through a capillary tube obtained by removing the wire from a thin electric cable. […]
Anno LIV – n.4 – ottobre/dicembre 2021 Termometro assoluto con diodi
An electronic linear PTAT (Proportional To Absolute Temperature) thermometer for didactical purposes is discussed and suggested as a laboratory instrument. Building this device helps students go deep into semiconductor physics. […]
