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, […]

Un elettroscopio Nuffield a microbilancia come un’alternativa all’elettroscopio a foglie d’oro nell’insegnamento dell’elettrostatica. (Traduzione da School Science Review, vol. 71, n. 257, Giugno 1990, a cura di Matilde Cilento)

A new approach to the teaching of electrostatics is described which avoids the well-known conceptual difficulties of the gold leaf electroscope. Simple equipment is used which the pupils can make for themselves for a few pence in a few minutes; and the experiments are both spectacular and fun. […]

Un esempio di utilizzo di una piccola stazione meteorologica

A simple meteorological station, connected on-line to a personal computer, has been used at the same time by teachers in physics and science, with students of high level school, in a scientific Liceum. Within the physics course, student made some hardware/software test of the automatic acquisition system; […]

Un’esperienza con differenze di potenziale variabili nel tempo

After introducing the concept of electric potential difference to students in the last year of secondary school, an experiment using a variable frequency generator, an oscilloscope and a loudspeaker allowed them to “see” and “hear” variable potential differences. The experiment was the starting point for an empirical introduction to decomposing electrical signals into sinusoidal components. […]

Un’esperienza di Alternanza Scuola Lavoro

The article is about a recent innovative experience of ‘work-related learning’ which took place in the school year 2015-2016 and involved a third class of Liceo Cecioni, a high school with a scientific specialization. The whole class was involved simultaneously. Our students were equipped with a professional accelerometer VectorNav VN-100: starting from the time series containing the three-axis accelerometer measurements they had to reconstruct, […]

Un esperimento “classico” rivisitato: la misura di h con i LED

A variation of the “classical” experiment for the measurement of Planck’s constant h using LEDs was proposed at the 2018 AI F Summer school of L’Aquila. This variation, in which the discharge of a capacitor provides the needed variable voltage and the measurements are made with an Arduino board, […]

Un esperimento per determinare l’andamento del rapporto Q/V per un conduttore qualsiasi

This article describes a simple method to experiment the relation Q/V=const, by means of the direct measurement of Q and V. The necessary equipment can be easily found in any physics laboratory, as it is basically made of a 0-600V dc generator, […]

Un esperimento per introdurre il caos deterministico nei licei

In this work it is shown how it is possible to build a simple device: the dripping faucet. This physical system exhibits an extremely interesting dynamic behaviour, useful to introduce the subject of deterministic chaos in high schools […]

Un esperimento per sfida: X Scotch

Triboluminescence was studied using a self-built 8-litre vacuum chamber operated at a pressure of about 1mtorr. Luminescence is observed in the chamber along the peeling line of an unrolled adhesive tape. The tribo-mechanism produced electrons and X-rays are revealed by the intense luminescence of a BGO crystal positioned close to the peeling line. […]

Un esperimento sulla dissipazione in un sistema meccanico

A simple dissipative mechanical system is discussed in order to introduce, at high school level, the basic ideas on which are founded some typical experimental techniques concerning condensed matter. Some reflections are made concerning the passage from a macroscopic description to a microscopic one. […]

Un’idea per un trasduttore di temperatura

This article shows how students can be taught the concept of using a transducer to measure the temperature with a very simple electronic circuit in which a NTC thermistor acts as sensor. Only a basic knowledge of the main properties of transistors and thermistors is required. […]
