Sieg, Philip G.; Berner, William; Harnish, Peter K.; Nelson, Philip C. – Physics Teacher, 2019
Climate is a topic of great concern to students, but it remains difficult to discuss scientifically. We are bombarded daily by emotional messaging for and against the proposition that human activities are altering the climate in ways that may have catastrophic effects. But it often seems that those predictions rest entirely on massive computer…

Heafner, Joe – Physics Teacher, 2019
In anticipation of "AstroNotes" articles planned for the near future, a short primer on certain fundamental aspects of the celestial sphere and its associated geometry is in order. While astronomers proper and longtime astronomy faculty will already be familiar with this topic, newer faculty and perhaps those from other disciplines, but…

Hosey, Dan – Physics Teacher, 2019
The High Road/Low Road race is often used as a qualitative prediction activity. A marble is released simultaneously on two elevated tracks that differ only in the middle section where the Low Road dips before finishing at the same height as the High Road. Typically a minority of students correctly predict that the Low Road will finish first. In…

Kapotis, Efstratios; Symeonides, Chrysoleon – Physics Teacher, 2019
The compensation pendulum is a pendulum that is constructed in a way that its length does not vary by changes of temperature. As the temperature of the air around the clock goes up, the rod of a regular pendulum clock mechanism expands and the clock runs slower. Historically, it has proven easier to compensate for changes in the ambient…

Cruz, Frederico Alan de Oliveira; dos Santos, Léo Rodrigues M.; Carvalho, Paulo Simeão – Physics Teacher, 2019
Within the new world perspective, it is expected that the school, as a formal education space, will be able to provide students with the basic information regarding human knowledge accumulated over the years, and also help them be capable of understanding various scientific and technological issues present today. In the specific case of knowledge…

Keller, Philip – Physics Teacher, 2019
Before students learn Kirchhoff's rules, they are typically taught how to solve "combined series-parallel" circuits. The method presented in many textbooks begins by drawing a series of simplified circuits, replacing series and/or parallel elements with their equivalent resistances, eventually reducing the circuit to a voltage source and…

Bodensiek, Oliver; Sonntag, Dörte; Wendorff, Nils; Albuquerque, Georgia; Magnor, Marcus – Physics Teacher, 2019
Since the emergence of augmented reality (AR), it has been a constant subject of educational research, as it can improve conceptual understanding and generally promote learning. In addition, a motivational effect and improved interaction and collaboration through AR were observed. Recently, AR technologies have taken a major leap forward in…

Önder, Fatih; Önder, Esra Bìlal; Ogur, Mehmet – Physics Teacher, 2019
In a classical electronic laboratory, there is an experiment where a diode is connected in a series with a resistor and a variable DC voltage source in order to draw the characteristic I-V curve of the diode. Input voltage is gradually increased starting from 0 V, and the potential difference between the diode's terminals is read by using a…

Margoniner, Vera; Bürki, Jérôme; Kapp, Micaela – Physics Teacher, 2019
In fall 2014 we started the development of a series of short YouTube videos to help our introductory physics students better comprehend concepts they tend to find challenging. Our work is inspired by the PhD thesis of Derek Muller (author of the Veritasium channel) showing that lecture-based videos tend to be not only ineffective, but actually…

Sullivan, Kelley D. – Physics Teacher, 2019
The ubiquitous bouncy ball, or "superball," is an engaging child's toy that has endured for more than 50 years. But what makes a bouncy ball so uniquely suited to its name? Steel balls, for example, are more highly elastic than are butadiene bouncy balls. Yet it is butadiene balls, and not steel balls, that appear in toy stores and…

Davis, C. E.; Piffer, J. L.; Cohen, M. D.; Polley, J. P. – Physics Teacher, 2019
Many physics textbooks describe the way in which a capacitor in an RC circuit charges and discharges over time. A circuit that consists of a capacitor that is connected to a voltage divider as shown in Fig. 1 is commonly addressed, but the textbooks limit the discussion to the time immediately after the switch is closed and a long time after the…

Lincoln, Don – Physics Teacher, 2019
All physics is fascinating, but some stories are more exciting than others. A story that involves some of the most precise measurements ever made and a tantalizing discrepancy might be one of the most interesting. Throw in a 3200-mile journey, a heavily laden truck covered by a tarpaulin, closed-down highways with police escorts, and hushed…

Absher, Mikayla L.; Piephoff, Caroline C.; Sitar, David J. – Physics Teacher, 2019
Throughout time people have been measuring the rising and setting positions of celestial objects with respect to the horizon. The motivation for this paper is to provide a link between mathematical and observational approximations for the Sun's declination (angular distance from the celestial equator). One source had students do an experiment with…

Olmstead, Matt – Physics Teacher, 2019
Throughout students' careers in physics, there are some topics that they learn multiple times and in multiple ways, and other topics that are briefly, if at all, discussed. I wanted to have the students think about all of the different physics topics they had learned in, most likely, a new way. Games have been used as a way to learn new physics…

Holmes, N. G.; Smith, Emily M. – Physics Teacher, 2019
Calls for reform to instructional labs mean many instructors and departments are facing the daunting task of identifying goals for their introductory lab courses. Fortunately, the American Association of Physics Teachers (AAPT) released a set of recommendations for learning goals for the lab to support lab redevelopment. Here we outline the…
