Larnder, Chris I. – Physics Teacher, 2021
Today's students are increasingly immersed in a landscape of screens and handheld digital devices through which a good deal of their interactions with the world around them are mediated. Physics educators, meanwhile, continue to rely on traditional human interactions with the physical world, such as sliding down a ramp or throwing a baseball, in…

Espindola, P. R.; Cena, C. R.; Alves, D. C. B.; Bozano, D. F.; Goncalves, A. M. B. – Physics Education, 2018
The study of buoyancy becomes very interesting when we measure the apparent weight of the body and the liquid vessel weight. In this paper, we propose an experimental apparatus that measures both the forces mentioned before as a function of the depth that a cylinder is sunk into the water. It is done using two load cells connected to an Arduino.…

Patrick, Amanda L. – Journal of Chemical Education, 2020
Mass spectrometry is one of the few instrumental analysis techniques that can be relatively well-understood with physics/chemistry knowledge typical of an advanced high school or a beginning undergraduate student. This positions mass spectrometry well to be used as a bridge between abstract concepts typically set as learning goals in courses at…

Kodejška, Cenek – Physics Education, 2018
This work focuses on the experimental demonstration of the hydrostatic paradox using simple tools in the form of plastic bottles and plastic syringes with a thread. For the evaluation of the results obtained the data logger Lab Quest Vernier was used. The construction of the device is presented in the first part of this paper. The second part…

Özcan, Hasan; Kostur, Hakki Ilker – Science Education International, 2019
Recently, with the influence of science, technology, engineering, and mathematics education approach, the material design has become an important aspect within science courses. The material development course in science curriculums is a unique opportunity to evaluate pre-service teachers' material designs. In this study, student science teachers'…

Mattox, J. R. – Physics Teacher, 2017
I report an innovation that provides a compelling demonstration of rocket propulsion, appropriate for students of physics and other physical sciences. An electrical spark is initiated from a distance to cause the deflagration of a combustible vapor mixed with air in a lightweight plastic bottle that is consequently propelled as a rocket by the…

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…

Jewett, John W., Jr. – Physics Teacher, 2016
This is the second in a series of two articles on using antique devices to teach introductory physics. As mentioned in the first article, students can more clearly see the physics required for the operation of antique devices than for modern-day technological devices. This article further discusses antiques used to teach vibrations and waves,…

Messerle, Louis – Journal of Chemical Education, 2018
iSchlenk, a portable instructional cart with equipment for hands-on student experience in safe handling of air-sensitive, moisture-sensitive, toxic, pyrophoric, and/or radioactive chemical materials, is described. The cart, for use by =4 students, has compressed air and vacuum from a diaphragm vacuum pump supplied to 4 three-port Schlenk lines…

Perry, Spencer B.; Gee, Kent L. – Physics Teacher, 2014
Vortex cannons have been used by physics teachers for years, mostly to teach the continuity principle. In its simplest form, a vortex cannon is an empty coffee can with a hole cut in the bottom and the lid replaced. More elaborate models can be purchased through various scientific suppliers under names such as "Air Cannon" and…

Branca, M.; Soletta, I. – Physics Teacher, 2014
One of the basic ideas when studying science is that matter is composed of particles (atoms or molecules) and these are in a constant state of agitation. In the solid or liquid state the molecules are attracted to each other, while in the gaseous state they have sufficient energy to overcome the forces of cohesion and can move away from one…

Eshach, H.; Volfson, A. – Physics Education, 2015
In the present paper we suggest an original physical explanatory model that explains the mechanism of the sound amplification process in a stethoscope. We discuss the amplification of a single pulse, a continuous wave of certain frequency, and finally we address the resonant frequencies. It is our belief that this model may provide students with…

Cross, Rod; Lindsey, Crawford – Physics Teacher, 2014
The effect of the aerodynamic drag force on an object in flight is well known and has been described in this and other journals many times. At speeds less than about 1 m/s, the drag force on a sphere is proportional to the speed and is given by Stokes' law. At higher speeds, the drag force is proportional to the velocity squared and is…

Ng, Pun-hon; Chan, Kin-lok – Physics Education, 2015
In most secondary physics textbooks, waves are first introduced with examples of mechanical waves because they can be illustrated by drawings and photographs. However, these illustrations are static and cannot reflect the dynamic nature of waves. Although many mechanical waves (e.g. water waves and vibrating strings) can be easily shown using…

Zietz, Otto; Mylott, Elliot; Widenhorn, Ralf – Physics Teacher, 2015
Planar x-ray imaging is a ubiquitous diagnostic tool and is routinely performed to diagnose conditions as varied as bone fractures and pneumonia. The underlying principle is that the varying attenuation coefficients of air, water, tissue, bone, or metal implants within the body result in non-uniform transmission of x-ray radiation. Through the…
