During the last decade Educational Research in many countries of the world has been dealing with the question of the lack of participation of girls in science education, especially in physical and technological sciences. This article reviews the most the issues, […]
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; […]
Some considerations concerning the Physics of matter are made. In particular we stress that the knowledge of some general aspects of modern physics (like atomic and molecular physics, do not help in the teaching of the elementary physics, especially as far as every-day phenomena are concerned. […]
This article deals with the very familiar phenomena in which vapour condenses, clouds are formed and, finally, it rains. It explains how this happens and why surface shape and not only temperature plays an important role in the process. […]
Four problems are discussed giving’ a schematic solution and an evaluation. […]
The Lenz law is studied experimentally using a permanent magnet falling inside metal tube. A home made force sensor is used to measure the weight of the tube and steady magnet before the experiment, and then to weight the vertically suspended tube when the magnet is dropped. […]
Using a Hall probe and a coil fed by a constant current, the line integral Ampere’s law can be measured. A simple method to approximate the integral by a finite sum is reported. […]
“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. […]
The article describes three programs, which simulate three physical events: (1) radioactive decay, (2) the motion of a ball in a basketball game, and (3) the launching of an earth satellite. […]
Some comments to the paper “Un adattatore di tensione fra lo standard americano e quello europeo” are here presented. A more detailed analysis in terms of complex impedances is worked out, and some suggestions for a safer handling of the device are given. […]
