Anno XXXVII - n.4 - ottobre/dicembre 2004 Le Nane Bianche, ovvero una “favola moderna”
As an appropriate conclusion of the physics course, a scheme is suggested for one or more lessons on white dwarfs, including some history and some theory. […]
Anno XXXVII - n.4 - ottobre/dicembre 2004 Costruire i diagrammi di fase dai dati sperimentali: una proposta didattica
An educational laboratory activity on phase diagrams based on computer online experiments and problem solving is presented. The phase diagrams are at the base of many technological processes involving materials with peculiar properties with which artifacts of our everyday life are produced. […]
Anno XXXVII - n.4 - ottobre/dicembre 2004 Una misura del calore prodotto per attrito
This paper describes a simple method for measuring the heat developed by friction, in which a thermometer in used as a calorimetric device. […]
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 XXXVII - n.3 - luglio/settembre 2004 Un’osservazione Galileiana. La misura del periodo di rivoluzione dei Pianeti Medicei
Galileo’s measurement of the period of revolution of Jupiter’s satellites was repeated in 18 days of observation, accurate measurements of the position of the satellites, their identification and the interpolation of their positions. The radii of the orbits of the four satellites and the mass of Jupiter were calculated. […]
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, […]
Anno XXXVII - n.3 - luglio/settembre 2004 Le orbite ellittiche e il Cabri Géomètre
The software Cabri Géomètre and a geometrical method essentially due to Richard Feynman are used to developa didactical approach towards Kepler’s first law (the law of elliptical orbits), starting from Newton’s gravitational law 1/R2. […]
Anno XXXVII - n.2 - aprile/giugno 2004 Heisenberg e la massa critica
An elementary treatment of the critical mass used in nuclear weapons is presented and applied to an analysis of the wartime activities of the German nuclear program. In particular, the work of Werner Heisenberg based on both wartime and postwar documents is discussed. […]
Anno XXXVII - n.2 - aprile/giugno 2004 Termodinamica e storia: un’esperienza didattica
Teaching thermodynamics through an historical approach improves the comprehension of the basic concepts and favors the interaction between teachers of different subjects. The paper reports on a cycle of seminars on the history of thermodynamics that were held in a secondary school of Palermo, […]
Anno XXXVII - n.2 - aprile/giugno 2004 Valore e attualità dell’insegnamento della fisica
What is really at the core of science education? What should every student remember about physics once he/she has left high school? We stress the importance of a basic knowledge and clear understanding of the scientific method as well as the cultural insight, […]
