Equilibrio termico: un’esperienza introduttiva a un percorso didattico.

This paper describes an introductory experiment, leading to a definition of temperature based on the use mercury thermometer. The variation in time of the thermometer readings is the starting point for the construction of a mathematical model; this model will be later adapted to more complex systems approaching thermal – […]

Esperimenti a “costo zero” sul moto uniforme

It is possible to study the uniform motion by using common objects taken from daily life. Cans, balloons, test tubes, olive oil and glycerine allow to make self-made devices, which are easy to handle and to use. The choice of using common materials let all students reproduce the most of this equipment at home and carry out the experiments by themselves. […]

Giochi ed esperimenti con le bottiglie di plastica

Some simple low cost demonstrations using plastic bottles of mineral water are reported. The experiments explore the pressure and weight of gases, Archimede’s law, gases dissolved in water, the Cartesian diver and other phenomena. […]

Gli anelli di Newton – allora e oggi

Working in the open air Newton measured the rings and from these measurements he calculated the “fit length” of light. The author repeated Newton’s measurements. Then when he went indoors using fluorescent light he was greatly surprised at what he saw. […]

I crateri formati dalle meteoriti

A brief analysis of meteorites and their effects on earth is given. In particular, the paper focuses on the relationship between the energy of a meteorite fallen on the earth and the width of the crater. The reader will find a very simple experiment that simulates the fall of a meteorite and allows to measure energy and the diameter of the crater. […]

Il laboratorio Elettricità-Luce al liceo “Quadri” di Vicenza

This article describes a laboratory activity undertaken by a group of students in the final year of a scientific high school. The main goals were to clarify the relationship between the microscopic models and macroscopic aspects of electrical properties of matter and to examine the effectiveness of teaching based on guided inquiry. […]

Il Mistero del forellino negativo. (traduzione da The Physics Teacher, novembre 1991, a cura di Silvano Sgrignoli)

“Negative pinholes” – black spots which are an optical reverse-counterpart for small holes – are a nice idea indeed and a good benchmark for the effectiveness of ray-tracing techniques. The article shows how an intriguing paradox raised by negative-pin-hole images can be turned into an interesting classroom activity. […]

Il moto dei corpi in un fluido viscoso: un’esperienza per valutare la resistenza del mezzo

This work describes an experiment, carried out with rather simple devices, on the quantitative study of the motion of some spheres, made of different materials, freely falling in water. We also propose a simulation program, written in Pascal language, allowing to compare the results of a theoretical model with the experimental data. […]

Il pendolo fisico: teoria, simulazione, esperimento

We propose a new tool for laboratory curricula based on computer-aided data acquisition and analysis. A pendulum coupled to a low-friction rotary sensor offers variable length, variable mass, and two different kind of damping torque: “dynamic friction” (almost constant) and “viscous” friction proportional to the angular velocity. […]

Il pendolo semplice

You can measure both the period and the amplitude of a simple pendulum “on the fly”, i.e. while it is swinging and slowing down. This was implemented years ago using a photogate connected to the serial port of a personal computer (which made the time measurements). […]
