Moya, A. A. – Physics Education, 2018
The introduction of electric circuit simulation software for undergraduate students in a general physics course is proposed in order to contribute to the constructive learning of electric circuit theory. This work focuses on the lab exercises based on dc, transient and ac analysis in electric circuits found in introductory physics courses, and…

Erol, M.; Çolak, I. Ö. – Physics Education, 2018
This paper reports a simple magnetically driven oscillator, designed and resolved in order to achieve a better student understanding and to overcome certain instructional difficulties. The apparatus is mainly comprised of an ordinary spring pendulum with a neodymium magnet attached to the bottom, a coil placed in the same vertical direction, an…

Samsonau, Sergey V. – Physics Education, 2018
This paper presents a set of laboratory classes to be taught as a part of a 1 year calculus-based physics class. It is composed of 7 modules designed to bring together experiments and computer simulations. Each module uses both simulations and experiments to address a phenomenon under study, and lasts for 3 weeks (21 weeks total for the whole…

Gyllenpalm, Jakob; Christiansson, Ulf; Friggebo, Patrik – Physics Education, 2018
Laboratory work in physics has traditionally focused on the verification of facts, theories and laws. In contrast, this article describes how laboratory tasks can be used to promote students understanding about the nature of science and scientific inquiry. In the project reported here, students learn about measurement uncertainties and a…

González, Manuel I. – Physics Education, 2017
Measuring voltage-current and voltage-power curves of a photovoltaic module is a nice experiment for high school and undergraduate students. In labs where real sunlight is not available this experiment requires a solar simulator. A prototype of a simulator using LED lamps has been manufactured and tested, and a comparison with classical halogen…

Ladino, L. A. – Physics Education, 2013
A different method to study the charging and discharging processes of a capacitor is presented. The method only requires a high impedance voltmeter. The charging and discharging processes of a capacitor are usually studied experimentally using an oscilloscope and, therefore, both processes are studied as a function of time. The approach presented…

French, M. M. J.; Hibbert, Michael – Physics Education, 2010
Oxygen is one of the component gases of air at room temperature, making up around 20% of the atmosphere. But can oxygen be liquified? This article details a method for making small amounts of liquid oxygen in the classroom if there is no access to a cylinder of compressed oxygen gas, and two methods for identifying the fact that it is liquid…

Gluck, P. – Physics Education, 2010
This article reports a high school laboratory project whose theme is the motion of a small ball on cycloidal tracks. Models were built both of a brachistochrone and of a Huygens pendulum clock whose bob is constrained to move on a cycloidal path. Photogates and a data acquisition system were employed in order to investigate experimentally the…

De Luca, R. – Physics Education, 2010
Using Faraday's law, one can illustrate how an electromotive force generator, directly utilizing seawater motion, works. The conceptual device proposed is rather simple in its components and can be built in any high school or college laboratory. The description of the way in which the device generates an electromotive force can be instructive not…

Picciarelli, Vittorio; Stella, Rosa – Physics Education, 2010
The topic of coupled oscillations is rich in physical content which is both interesting and complex. The study of the time evolution of coupled oscillator systems involves a mathematical formalization beyond the level of the upper secondary school student's competence. Here, we present an original approach, suitable even for secondary students, to…

Abdul-Razzaq, W.; Biller, R. D. – Physics Education, 2010
Introductory physics laboratories have seen an influx of "conceptual integrated science" over time in their classrooms with elements of other sciences such as chemistry, biology, Earth science, and astronomy. We describe a laboratory to introduce this development, as it attracts attention to the voltage induced in the human brain as it…

Gintautas, Vadas; Hubler, Alfred – Physics Education, 2009
Lessons and homework problems involving a pendulum are often a big part of introductory physics classes and laboratory courses from high school to undergraduate levels. Although laboratory equipment for pendulum experiments is commercially available, it is often expensive and may not be affordable for teachers on fixed budgets, particularly in…

Strawson, R. J. – Physics Education, 2009
If you have seen tubes like the ones we describe here in the back of a cupboard but have been reluctant to use them, now is the time to get them out. The aim of this article is to record the history of teaching about electron beams, particularly with Teltron equipment, and in doing so encourage those schools that are equipped with these tubes to…

Ruangsuwan, Chaiyapong; Arayathanitkul, Kwan – Physics Education, 2009
A low-cost celestial globe is developed to support astronomical coordinate learning. It is used for demonstrating how stars are positioned and to analyse the motion of celestial bodies or diurnal motion. The model was implemented at a weekend astronomy camp provided for students from schools in the northeastern region of Thailand. A series of…

Nopparatjamjomras, Suchai; Chitaree, Ratchapak; Panijpan, Bhinyo – Physics Education, 2009
To overcome students' inaccurate prior knowledge on primary additive colours, a coloured-light mixer has been constructed to enable students to observe directly the colours produced and reach the conclusion by themselves that the three primary colours of light are red, green, and blue (NOT red, yellow, and blue). Three closely packed tiny…
