Lenfestey, Mark – Physics Teacher, 2019
Students often find the study of electrostatics to be abstract, heavily mathematical, and non-intuitive. This paper describes an inquiry-based approach to teaching electrostatics in an introductory calculus-based physics class that emphasizes the primacy of student conceptual understanding.

Leftwich, Kendal M.; Ioup, Juliette W.; Seab, C. Gregory – Physics Teacher, 2019
We report here on an effort to involve high school physics students in research on impacts of oil spills on marine mammals at a local university. We believe that the effort described here might be useful to others who would like to involve physics students in research, especially work of an interdisciplinary nature. The students learn to work…

Hong, Joon Hee; Kim, Jung Bog – Physics Teacher, 2019
Ametal leaf electroscope has often been used for teaching electrostatics. For example, Fig. 1 is a very early one demonstrating electrostatic induction with a gold leaf electroscope. Alternatively we can charge the electroscope by touching a charged object to it. In both cases, induction or charging, the metal leaves push away from each other for…

Kelly, James – Physics Teacher, 2019
Ray diagrams are widely used in introductory physics textbooks to illustrate the behavior of ideal systems of lenses or mirrors in geometrical optics. Their virtue lies in their explicit display of multiple ray paths connecting object and image points, which leads naturally to an understanding of how a planar object is transformed into a planar…

Cook, Harry; Dudley, Scott C. – Physics Teacher, 2019
High voltage supplies are often used in physics classes for demonstrations and laboratory work. These devices deliver several thousand volts DC, while limiting the current to a safe level, typically under 5 mA. One issue with these power supplies is their expense, which means schools may not have one. Less expensive homemade units have been…

Polen, Carol – Physics Teacher, 2019
Particle physicists are literally rewriting what we know about the physical world; yet, the typical high school physics curriculum spends little to no time on particle physics. The purpose of this study was to determine whether the inclusion of the particle physics topic in the curriculum increased the engagement and knowledge of high school…

Ackerson, Bruce J. – Physics Teacher, 2019
Electromagnetic induction, represented by either Faraday's law or the Lorentz force law, produces many paradoxes requiring careful examination and application of these laws. The paradoxical example of induction, presented herein, arose in a class and is resolved within the framework of special relativity.

Syed, Maarij; Nuessle, N. – Physics Teacher, 2019
Magnets are familiar objects and yet magnetism as a concept remains challenging. A casual search of YouTube for magnets reveals a staggering number of videos, interesting demos involving electric and permanent magnets, and entire channels devoted to various uses for magnets. It is far more difficult to find descriptions that can help students…

Garver, Wayne – Physics Teacher, 2019
It is well known that when two waves are added they produce beats. These beats are the amplitude modulation of the initial waves and occur periodically at a rate equal to the frequency difference of the two waves. Acoustical beats arise from sound waves of nearly equal frequencies. Optical beats arise from the interference of two light waves of…

Lincoln, James – Physics Teacher, 2019
The hydrogen spectrum is one of the most commonly demonstrated and most commonly studied. After the visible spectral lines (Balmer series) are explained by the Rydberg's formula, it becomes immediately apparent that there will also be similar infrared and ultraviolet series. As you may have taught your students, these are called the Paschen and…

Briggs, Michael – Physics Teacher, 2019
The mystery tube is a fairly well known activity among science teachers for illustrating the nature of science. A variety of procedures have been presented for carrying out this activity, such as Scott Miller's method based on the BCSE 5E Instructional Model. Mystery tubes and other "black box" activities allow the students to engage in…

On August 16, 1960, at 7:12 a.m., United States Air Force Captain Joseph W. Kittinger Jr. looked out from his balloon gondola at a height of over 19 miles and… jumped. Kittinger's altitude and free-fall speed record lasted until Felix Baumgartner's jump from a height of nearly 24 miles on Oct. 14, 2012. Baumgartner broke several records, including…

Freericks, J. K.; Cutler, D.; Kruse, A.; Vieira, L. B. – Physics Teacher, 2019
We describe a new style of MOOC designed to engage students with an immersive multimedia environment including text, images, video lectures, computer-based simulations, animations, and tutorials. Quantum Mechanics for Everyone is currently running on edX and has been successful by a number of different measures. Building on the pioneering work of…

DiLisi, Gregory A.; Chaney, Alison; Brown, Greg – Physics Teacher, 2019
Fifty years ago this summer, three men aboard Apollo 11 traveled from our planet to the Moon. On July 20, 1969, at 10:56:15 p.m. EDT, 38-year-old commander Neil Armstrong moved his left foot from the landing pad of the lunar module (LM) Eagle onto the gray, powdery surface of the Sea of Tranquility and became the first person to step onto the…

Harder-Viddal, Candice – Physics Teacher, 2019
There have been many recent articles in this journal highlighting simple demonstrations of a wide variety of acoustic phenomena. In introductory physics courses, sound waves and their propagation through air, and resonance in musical instruments, are covered in detail. However, attention is not usually paid to the active role that our ears play in…
