Salgueiro da Silva, M. A.; Seixas, T. M. – Physics Teacher, 2020
The ammeter-voltmeter method is a general method for measuring electrical resistances that is widely used in the introductory physics laboratory, mostly for pedagogical reasons. Simultaneous readings of current (I) and voltage (V) allow the calculation of electrical resistance (R) using Ohm's law: R = V/I. It is implicitly assumed that electrical…

Sanders, James C. – Physics Teacher, 2020
The ballistic pendulum apparatus is a fairly ubiquitous element of the introductory physics laboratory, as the pendulum and launcher gun can be used together or independently to demonstrate a variety of concepts from conservation laws to projectile motion to the motion of a physical pendulum. In this work, we control the launch speed of the gun to…

Kent-Schneider, Isaiah; Kruse, Jerrid – Physics Teacher, 2020
Within physics education research (PER), inductive teaching strategies (e.g., inquiry-based teaching) have long been a goal. Yet others do not seem to be convinced that consensus exists with respect to the goals of physics education and identify three possible goals as: (1) to teach practical, factual knowledge, (2) to develop deep understandings…

D'Anna, Michele; Corridoni, Tommaso – Physics Teacher, 2020
In a traditional teaching approach, a physics course begins with mechanics, and generally the braking effect due to magnetic interactions is not mentioned among the various types of friction presented (static, sliding, rolling) because students will discover magnetism only in later chapters. In our didactic experience this traditional choice is…

Frodyma, Marc – Physics Teacher, 2020
Students have difficulty bridging the conceptual gap between Newtonian and relativistic physics, and, consequently, the teaching of special relativity has been discussed extensively in the literature. A comprehensive list of such references is too large to include, but a brief list is given. In this paper, the author presents several exercises,…

de Winter, James – Physics Teacher, 2019
It is common for high school physics teachers to comment on the challenges they face in supporting students' graph drawing skills, knowing their importance for the study of physics. This paper suggests a novel and alternative way to support students to develop their graph drawing skills as well as teach them about sound, frequency, and amplitude.…

Goncalves, Alem-Mar B.; Freitas, Welica P. S.; Reis, Diogo D.; Cena, Cicero R.; Alves, Diego C. B.; Bozano, Doroteia F. – Physics Teacher, 2019
The popularization of microcontrollers like Arduino bring new possibilities of experiments for physics laboratories. For instance, load cell sensors have been used in experiments on impulse and buoyancy. Here we propose an experimental apparatus using Arduino connected to a load cell to measure surface tension by the du Noüy method (or ring…

Kouh, Minjoon – Physics Teacher, 2022
The importance of introducing computational approaches early and actively in science education is widely acknowledged among educators and scientists. Many great ideas have been put forward and implemented by advocates and organizations such as Partnership for Integration of Computation into Undergraduate Physics (https://www.compadre.org/PICUP)…

Doucette, Danny; Singh, Chandralekha – Physics Teacher, 2022
Imagine two groups of students in your physics class or lab. In Group A, the students each take on a different task but invest an equal amount of time, energy, and effort in what they do. For example, one student might be the note-taker, while another operates the calculator, computer, or experimental apparatus, and a third keeps everyone on track…

Aok, Yoki; Yawata, Kazushi – Physics Teacher, 2022
A new system for tracking a metal ball rolling on the slope of the touch panel of a tablet computer was developed. The widespread introduction of tablets in educational environments allows the use of a convenient dynamic measurement in schools.

Denny, Mark – Physics Teacher, 2022
A classical mechanical structure with an internal degree of freedom is shown to reflect off a potential well. Such behavior is impossible for point-like or rigid classical particles. This numerical study provides insight for students studying internal energy and degrees of freedom.

Ärlebäck, Jonas Bergman; Albarracín, Lluís – Physics Teacher, 2022
Enrico Fermi is remembered for his many contributions to theoretical and experimental physics, but from an educational point of view he also popularized the use of the kind of questions we now call "Fermi problems" (or "Fermi questions"). Fermi problems (FPs) are back-of-envelope problems that arose from the need to make order…

Hull, Michael; Spitzer, Philipp; Hopf, Martin – Physics Teacher, 2020
Recently, Greta Thunberg has strongly increased environmental awareness with the climate strikes and the resulting Fridays for Future movement. But what does environmentally friendly behavior look like? In today's society, it is a sort of common sense that one should recycle. From an early age, we are taught in school that recycling conserves…

Lin, Zhiqi; Xie, Yuchan; Tu, Chaoshi – Physics Teacher, 2023
Acceleration of moving objects is usually measured by photoelectric gates. In this paper, a method of acceleration measurement is proposed by pasting white card stock and black tape on a pulley and then using an Arduino to time the motion. This method only needs one photoelectric sensor to measure the acceleration. In contrast, using photoelectric…

Zhang, Jiarui; Zhang, Junhui; Chen, Qiushi; Deng, Xiaorong; Zhuang, Wei – Physics Teacher, 2023
With the development of digital technology, plentiful sensors are embedded in the smartphone, which makes it a valuable tool for teaching elementary experimental physics. For instance, the magnetic field sensor of the smartphone has been used to measure gravitational acceleration by measuring the magnetic pendulum's oscillation period. The…
