Kettle, Maria – Physics Education, 2020
Short videos are widely used in secondary level physics classes, part of a portfolio of strategies for teaching and learning. However, research into how they are used, why they are used and the optimum design for learning is in its infancy. This paper seeks to examine how videos are used in UK physics classrooms for the communication of physics…

Martins, J. E. M. Perea – Physics Education, 2020
This work presents a sequence to introduce resistive gas sensors in the classroom. It explains the physical principle of the metal oxide semiconductor sensors and exemplifies its real interfacing through the sensor model MQ-2. Besides, it also presents the design of two electronic systems to indicate the level of alcohol concentration in the air,…

Leone, Matteo; Rinaudo, Marta – Physics Education, 2020
Over the past few decades a growing awareness has developed in the science education community about the educational power of the history of science. Yet, the historical approach is not implemented in many ministries of education policies. In order to investigate what factors contribute to this, we have conducted a survey of attitudes toward the…

Pendrill, Ann-Marie – Physics Education, 2020
Your body is not a point particle. The nature and direction of the forces counteracting gravity influence your experience of uniform rectilinear motion--as does your own orientation in relation to the force of gravity. Sensors in smartphones or other devices can capture these forces, and help establish a connection between the personal experience…

Ruiz, Michael J.; Berls, Rob – Physics Education, 2020
A vacuum cleaner is used to isolate over twelve harmonics in a corrugated toy whistling tube. The toy tube is first taped along a horizontal surface. Then a vacuum cleaner with a hose diameter approximately the same as that for the toy tube is turned on. As the vacuum cleaner hose approaches one end of the corrugated tube, individual higher…

de Almeida, Pamella Aline; Onisaki, Hadassa; de Almeida, Juarez Trindade; Costa, Lúcio Campos; Brockington, Guilherme – Physics Education, 2020
Principles of conservation are essential to the physical understanding of the universe. When thinking about its teaching, especially aimed at basic education, experimental activities can be great allies for its understanding. In this article, we present a demonstrative model using a fidget spinner arranged in a structure constructed using 3D…

Ivanov, Dragia; Nikolov, Stefan – Physics Education, 2020
In this paper we consider the well-known experiment with the 'heavy' newspaper that breaks a stick that it is laid on. Using several appropriate control experiments we show that the currently invoked explanation using atmospheric pressure cannot be correct. We perform a theoretical analysis and propose a new explanation based on the rotational…

Rinaldi, R. Gustav; Fauzi, Ahmad – Physics Education, 2020
The recent works of oscillators are mainly focused on underdamped oscillation. Therefore, the writer proposes an experimental apparatus to demonstrate all types of damped harmonic oscillation. The apparatus utilizes an Arduino for data acquisition and an Excel spreadsheet for data analysis. By using this apparatus, the type of damped harmonic…

Cross, Rod – Physics Education, 2020
If a ball rolls at constant speed on a horizontal surface about a horizontal axis then the angular velocity is easily measured. If the ball is projected with additional spin about the vertical axis, then the rotation axis is tilted and it is more difficult to measure the rotation speed. A few examples are presented to show how the separate topspin…

Nuryantini, Ade Yeti; Nuryadin, Bebeh Wahid – Physics Education, 2020
The vector of aircraft motion and analysis using FlightRadar24 and Tracker motion analysis has been investigated and studied. The straight, turning and circular aircraft motion were recorded from www.flightradar24.com using a commercial desktop video recording. Then, the video of the aircraft motion was analyzed using Tracker 5.1.1 to determine…

Priyanto, Aan; Rahmawati, Ita; Aji, Mahardika Prasetya – Physics Education, 2020
An experiment using the volumetric flux of a water stream was used to find the initial velocity of the water as it performs parabolic motion. The trajectories were measured with different initial velocities, comparing the maximum height and range values with the theoretical calculations. The closeness of the measured values to the calculations…

Silveira, M. V.; Barthem, R. B.; Santos, A. C. F. – Physics Education, 2020
This work presents an experiment that seeks to simulate human color vision through electronic components in an attempt to build, together with the students, a cybernetic 'eye'. The limitation of the cybernetic eye developed here in relation to the standard human chromatic vision, which makes it a 'colorblind eye', is an argument to be explored by…

Malisorn, Khemchira; Wicharn, Surawut; Plaipichit, Suwan; Pipatpanukul, Chinnawut; Houngkamhang, Nongluck; Puttharugsa, Chokchai – Physics Education, 2020
This paper demonstrates the use of smartphones in an experiment of light absorption and light scattering. The LED display and camera of the smartphone are used as the light source and as the detector, respectively. The color wheel is used to choose the color of the light source to be shone through the sample for analysis. The detector directly…

Kersting, Magdalena; Toellner, Richard; Blair, David; Burman, Ron – Physics Education, 2020
In recent years, general relativity (GR) and gravitational-wave astronomy have emerged both as active fields of research and as popular topics in physics classrooms. Teachers can choose from an increasing number of modern instructional models to introduce students to relativistic ideas. However, the true potential of an instructional model can…

Hechter, Richard P. – Physics Education, 2020
'It is the belt!' This is how middle school teachers in a science teaching professional development program rationalized why they believe Orion is the most recognizable of all constellations in the night sky. It was from this foundation that we chose Orion to be the focus of a four-phase ethnoastronomy-based project reported here. Ethnoastronomy,…
