The aim of this paper is to investigate the stability of a bottle filled with different volumes of water, and to determine the angle at which it topples over for each volume of water. Data for the angle at which the bottle toppled were gathered experimentally using a cylindrical 1 litre bottle, and two theoretical models were then developed,…

The aim of the present article is to focus on the operational aspects referring to the actions--strategies and on the defined modalities of establishing educational objectives/competences. In the achievement of our work a special attention has been paid to the operational aspects of the learning process of the optical phenomena. There were carried…

Heid, Christy; Rampolla, Donald – Physics Teacher, 2011
Many illustrations and problems on the vector nature of forces have weights and forces in a vertical plane. One of the common devices for studying the vector nature of forces is a horizontal "force table," in which forces are produced by weights hanging vertically and transmitted to cords in a horizontal plane. Because some students have…

Whyntie, T.; Parker, B. – Physics Education, 2013
The Timepix hybrid silicon pixel detector has been used to investigate the inverse square law of radiation from a point source as a demonstration of the CERN [at] school detector kit capabilities. The experiment described uses a Timepix detector to detect the gamma rays emitted by an [superscript 241]Am radioactive source at a number of different…

Piva, M. – Physics Teacher, 2009
In introductory-level physics courses, the concept of surface tension is often illustrated using the example of capillary rise in thin tubes. In this paper the author describes experiments conducted using a planar geometry created with two small plates forming a thin wedge. The distribution of the fluid entering the wedge can be studied as a…

Gancheff, Jorge S.; Kremer, Carlos; Ventura, Oscar N. – Journal of Chemical Education, 2009
A computational experiment aimed to create and systematically analyze models of simple cation hydrates is presented. The changes in the structure (bond distances and angles) and the electronic density distribution of the solvent and the thermodynamic parameters of the hydration process are calculated and compared with the experimental data. The…
