The trajectories of charged particles in the non-uniform magnetic field generated by two parallel identical currents are studied. Although this case is not usually considered in the high school, its basic aspects are not too difficult and can be understood by the students. […]
This article shows how to make equipment for studying the performance of a water rocket, e.g. its acceleration versus air pressure and mass. […]
An experiment made by some students of the “Liceo Scientifico” about the motion of an air bubble in a tube filled with water. What is the inclination of the tube for the highest speed of the bubble? […]
The falling motion of a drop of distilled water inside a transparent graduated cylinder containing domestic olive oil was studied. The results of the measurements taken were worked out so that a direct proportionality between the velocity of the drop and the area of its maximum cross section could be verified. […]
This article the presents the results of a research on the change of electric voltage across a voltmeter, during the solution of a wheat of salt. It could be a stimulus for subsequent developments, even involving the class and the chemistry teacher in the project area of the biennium of the technical industrial institutes. […]
The 1957 Nobel Prize awarded to Tsung Dao Lee and Cheng Ning Yang aroused the interest of the public. The article aims to illustrate the importance of the work of Lee and Yang in a simple way, comprehensible to lay people with little or no knowledge of modern physics. […]
