Eichenlaub, Mark – Physics Teacher, 2022
There is a close connection between simple harmonic motion and uniform circular motion. This connection is widely taught and included in standard textbooks. Here, we exploit this connection to simultaneously derive two results from introductory mechanics: the period of a mass-spring system and the centripetal acceleration formula. Previously…

Wehrbein, William M. – Physics Teacher, 2022
Recognized as one of the most beautiful experiments of all time, the oil drop experiment performed by Robert Millikan and his graduate students (primarily Harvey Fletcher) is a standard in the repertoire of experiments performed by undergraduate physics students. However, "as a teaching lab it does not enjoy a good reputation for three…

Zhu, Guangtian; Ding, Yi; Chen, Qingwei; Huang, Yuhan – Physics Teacher, 2022
Instructional videos are commonly used in both remote and in-campus curriculum. In order to investigate students' experience when learning with online instructional videos, we adapted a method called "UX curve" from the user experience studies in industrial design. In this paper, we introduce the procedure and data processing method of…

Sánchez, María Jesús; Gil, Julia; Manuel Vaquero, José – Physics Teacher, 2022
The camera obscura is a well-known optical device in the form of a closed box with a hole in one of its walls through which light rays pass, forming an inverted image of the external objects on the opposite wall, as can be seen in Fig. 1(a). Despite the simplicity of its basic design, they have been widely used by scientists and artists. In…

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)…

Mathis, Clausell; Southerland, Sherry – Physics Teacher, 2022
In this paper, we describe the work of a teacher (Sarah) as she attempted to use culturally relevant pedagogy in her physics classroom. Culturally relevant pedagogy (CRP) is an approach to teaching developed by Gloria Ladson-Billings, with the goal of encouraging learning through drawing on students' cultural capital as a centerpiece of their…

Galeriu, Calin – Physics Teacher, 2022
The determination of the speed of sound in air is a classical experiment, usually performed with a resonance tube apparatus. The measured value can be checked against Eq. (1), which describes the temperature dependence of the speed of sound in dry air. A modern implementation of this speed of sound investigation uses an Arduino Uno microcontroller…

Robertson, Amy D.; Goodhew, Lisa M.; Heron, Paula R. L.; Scherr, Rachel E. – Physics Teacher, 2022
Perhaps the most commonly cited student idea about forces in the literature is the notion of an impetus force, defined as the "belief that there is a force inside a moving object that keeps it going and causes it to have some speed," that can then "fade away as the object moves along." According to the literature, even after…

Dorsel, Dominik; Staacks, Sebastian; Heinke, Heidrun; Stampfer, Christoph – Physics Teacher, 2022
As smartphones have become a part of our everyday life, their sensors have successfully been used to allow data acquisition with these readily available devices in a variety of different smartphone-based school experiments. Such experiments most commonly take advantage of the accelerometer and gyroscope. A less frequently used sensor in…

Eberly, B.; Lincoln, D. – Physics Teacher, 2022
Neutrinos are perhaps the least understood of the known denizens of the subatomic world. They have nearly no mass, interact only via the weak nuclear force and gravity, and, perhaps most surprising, the three known species of neutrinos can transform from one variant into another. This transformation, called neutrino oscillation, has been…

Becchetti, F. D. – Physics Teacher, 2022
There is an ongoing challenge with STEM education: making physics, math, and science, in general, interesting, understandable, and retentive for college science and non-science majors, K-12 students, and the public. If not imparting detailed knowledge, at least one would like to introduce important concepts that will be remembered, appreciated,…

Çoban, A.; Erol, M. – Physics Teacher, 2022
Ever increasing technological progress opens novel opportunities concerning educational activities, and the ability to use the technology effectively is one of the 21st century's most demanding skills. The Partnership Forum for 21st-Century Skills (P21) states that no organization can achieve satisfying results without using technology and…

Baker, Blane; Sherer, Maggie; Mossinghoff, Ben; Laycock, Will – Physics Teacher, 2022
A wood cantilever of length ~2.5 m is driven into resonance using the hand as a simple driver. Video recordings of these oscillations are analyzed to determine experimental second harmonic (n = 2) damped resonance frequencies. These frequencies are compared to theoretical ones, obtained from measurements of elastic moduli, damping properties, and…

Pal, Arnab; Panchadhyayee, Pradipta; Sahu, Kriti R.; Syam, Debapriyo – Physics Teacher, 2022
The refractive index is a number that governs how light changes its direction of propagation as it enters one material medium from another. This phenomenon is known as refraction and the angles of incidence and refraction of light, referred to the normal to the interface of the two media at the point of incidence, are related by Snell's law. The…

Wargo, Brian M. – Physics Teacher, 2022
The Next Generation Science Standards (NGSS) is the latest initiative to promote authentic scientific work in the classroom. Previous reform efforts have not caused the change in teacher practice and student learning that was hoped for, despite their ubiquity and accessibility. The culprit may be the culture of school that is often recalcitrant to…
