Santosa, I. E. – Physics Education, 2022
The image of free-falling bar has been recorded to study the effect of the motion on its observed length. This moving bar image is analysed using the Tracker software to determine its length and the end bar's position. An elongated appearance of the bar has been observed with movement. This effect relies on the speed and the exposure time during…

Biswas, Subhrajyoti – Physics Education, 2022
In this article we present a simple experimental set-up to determine the band gap of germanium and silicon using the "ExpEYES-17" kit. The experiment is based on the temperature dependence of the reverse current through germanium and silicon diodes at different temperatures. The experimental values are found to agree well with accepted…

Martins, J. E. M. Perea – Physics Education, 2022
This work presents the design of an inexpensive electronic system to measure water temperature and generate an experimental data set used to verify the fitting between experimental and theoretical curves of a water-cooling process. The cooling constant is computed with three different theoretical methods to check their efficiency and this approach…

Singh, Rohit; Singh, Amit Kumar; Singhal, Sonal – Physics Education, 2022
Air pollution is one of our day's significant reasons for human health problems and affects every community throughout the world. Monitoring air pollution is a key aspect of raising awareness and pollution mitigation approaches followed by different nations. This paper targets to develop a low-cost Internet of things-based embedded system to…

Paixão, P. A.; Remonatto, V. M. C.; Calheiro, L. B.; Dos Reis, D. D.; Goncalves, A. M. B. – Physics Education, 2022
Here, we present a 3D printed experimental apparatus that students can use to acquire interference and diffraction quantitative data from light passing through a single or double-slit experiment. We built a linear screw stage with a multiturn potentiometer connected to its leadscrew as a position sensor. Using an Arduino, we collected light…

Singh, Sushil Kumar; Lalit, Khushi; Kaur, Kawaljeet; Kaur, Savinder – Physics Education, 2021
We present a computer-based experiment that simulates the accretion process and generates fluffy aggregates with fractal nature. The Box Counting is performed without the aid of an image processing tool by using the coordinate information of the constituents of the aggregate. A simple algorithm to create aggregate and calculate box-dimension will…

Moya, Antonio Angel; Merino, Ana – Physics Education, 2022
We describe a simple STEM project for students to learn to measure atmospheric pressure by using a sensor of the type BMP180 together with the Arduino electronic platform. The collected experimental data, together with simple experiments, can be used to study the different pressure units and the relationship between pressure and force. Also, they…

Holz, Christoph; Pusch, Alexander – Physics Education, 2020
Powerbanks differ in the amount of energy they can store. Usually this capacity (in a colloquial sense) of the powerbanks is stated in the form of charge in mAh for effective advertising. From a physical point of view, shouldn't the energy that a powerbank can provide be of interest? For students, charging smartphones with power banks is…

Biswas, Subhrajyoti; Roy, Durjoy – Physics Education, 2022
At constant current (I) the forward bias potential (V) of a "pn" junction diode may be considered to vary linearly with temperature (t) within a temperature range. Based on this property we have constructed diode thermometer using germanium (Ge) and silicon (Si) diodes. The experimental "V-t" data at constant forward current…

Price, Colin B.; Price-Mohr, Ruth – Physics Education, 2019
We introduce a virtual physics laboratory, 'PhysLab', created using 3D video game technology suitable for advanced level physics courses in secondary schools. This comprises 32 simulated experiments covering a range of physics topics, selected in collaboration with practicing school teachers. PhysLab is made available at no cost for the physics…

Gelir, Ali; Kocaman, Merve; Pekacar, Ilgim – Physics Education, 2019
In conventional e/m experiments performed in undergraduate laboratories, generally a simple mechanical ruler is used to measure the radius of the circular trajectory of the electrons. But, the measurement error in this technique is mostly big and varies from one student to another. As an alternative to a mechanical ruler, we proposed a more…

Soares, A. A.; Borcsik, F. S. – Physics Education, 2016
In this work we present an inexpensive experiment proposal to study the kinematics of uniform circular motion in a secondary school. We used a PC sound card to connect a homemade simple sensor to a computer and used the free sound analysis software "Audacity" to record experimental data. We obtained quite good results even in comparison…

Klein, P.; Gröber, S.; Kuhn, J.; Müller, A. – Physics Education, 2014
Tablet computers were used as experimental tools to record and analyse the motion of a ball thrown vertically from a moving skateboard. Special applications plotted the measurement data component by component, allowing a simple determination of initial conditions and "g" in order to explore the underlying laws of motion. This experiment…

Kourkoumelis, C.; Vourakis, S. – Physics Education, 2014
This paper describes an interactive tool for analysis of data from the ATLAS experiment taking place at the world's highest energy particle collider at CERN. The tool, called HYPATIA/applet, enables students of various levels to become acquainted with particle physics and look for discoveries in a similar way to that of real research.
