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 LVI - n.3 - luglio/settembre 2023 Studio dell’illuminamento di una sorgente luminosa in un mezzo trasparente di spessore variabile
In this paper, after a historical introductory perspective on the absorbtion law of light by a transparent media, we describe an educational proposal using cheap, easily available material and a smartphone. The proposal is a useful tool for a class of high school students. […]
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 LVI - n.2 - aprile/giugno 2023 Teoria della misura: nodi concettuali e proposte didattiche
Recent research about the professional development needs as perceived by Italian physics teachers showed that measurement theory ranked last in a list of 17 physics topics. This result may be due to the fact that measurement theory is often taught just at the very beginning of physics courses in high school, […]
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. […]
Anno XXX - n.2 - aprile/giugno 1997 Trasformazione termodinamica isoterma on-line: un’occasione per discutere la realizzazione e la taratura di un trasduttore di volume
This paper presents a simple educational on-line experiment about gas (air) transformation. This experiment was performed using an intelligent serial interface (ULI) and a volume transducer designed for this purpose. The paper is divided into two parts: the first explains the design and the calibration of the volume transducer, […]
