Young, Chadwick; Young, Kaisa; Buxton, Gavin; Buzzelli, Armand – Physics Teacher, 2017
Every year, thousands of college students in the life sciences take introductory physics. Some educators have advocated physics be presented in a way that is relevant to these students. Most are biology majors, but many students are in the allied health field studying to become athletic trainers, occupational therapists, or professionals in some…

Spatz, Verena; Tampe, Jana; Slezak, Cyril – Physics Teacher, 2019
In the ever-changing landscape of educational practice and policy, educators oftentimes find it difficult to obtain adequate training and resources. This places a unique burden on education researchers to develop both content materials as well as professional development programs. The adoption and implementation of the federal No Child Left Behind…

Reich, Gary – Physics Teacher, 2016
Water has the unusual property that it expands on freezing, so that ice has a specific gravity of 0.92 compared to 1.0 for liquid water. The most familiar demonstration of this property is ice cubes floating in a glass of water. A more dramatic demonstration is the ice bomb shown in Fig. 1. Here a cast iron flask is filled with water and tightly…

Kortemeyer, Gerd – Physics Teacher, 2016
I think most physics teachers would agree that two important components of a proper solution to a numerical physics problem are to first figure out a final symbolic solution and to only plug in numbers in the end. However, in spite of our best efforts, this is not what the majority of students is actually doing. Instead, they tend to plug numbers…

Burin, Michael J. – Physics Teacher, 2016
This century's transits of Venus (2004, 2012) captured significant public attention, reminding us that the wonders of astronomy need not be confined to the night. And while nighttime telescope viewing gatherings (a.k.a. "star parties") are perennially popular, astronomy classes are typically held in the daytime. The logistics of…

Cross, Rod – Physics Teacher, 2016
A spinning top or a spinning hard-boiled egg is fascinating to observe since both objects can remain upright for a relatively long time without falling over. If spun at sufficient speed on a horizontal surface, the spin axis rises to a vertical position and the bottom end tends to remain fixed in position on the surface. If the initial spin is…

Regester, Jeffrey – Physics Teacher, 2016
A bridge rectifier is a diamond-shaped configuration of diodes that serves to convert alternating current(AC) into direct current (DC). In our world of AC outlets and DC electronics, they are ubiquitous. Of course, most bridge rectifiers are built with regular diodes, not the light-emitting variety, because LEDs have a number of disadvantages. For…

Vourlias, Kostas; Seroglou, Fanny – Physics Teacher, 2016
Could Usain Bolt achieve what teachers often fail to do? Could this famous Olympic winner challenge and motivate students to study mechanics and introduce them to the principles of physics in a fun way, outside of the classroom? In order to answer these questions, we "invited" for one semester the world record holder to visit our Greek…

Küçüközer, Asuman – Physics Teacher, 2015
The aim of this paper is to provide a way of teaching the factors that affect resistance using mechanical pencil leads and the brightness of the light given out by a light bulb connected to an electrical circuit. The resistance of a conductor is directly proportional to its length (L) and inversely proportional to its cross-sectional area (A).…

Megowan-Romanowicz, Colleen – Physics Teacher, 2016
In 1998 I had been teaching science for 13 years. I was a good teacher: I had the plaques and certificates to prove it. But often I felt like an impostor (which I have since learned is not unusual--70% of all people feel like a fake at one time or another). While my students could solve problems and ace tests, every June when I sat down to look at…

Phillips, Jeffrey A. – Physics Teacher, 2016
While entropy is often described as "disorder," it is better thought of as a measure of how spread out energy is within a system. To illustrate this interpretation of entropy to introductory college or high school students, several activities have been created. Students first study the relationship between microstates and macrostates to…

Ribeiro, Jair Lúcio Prados – Physics Teacher, 2015
If an object is conveniently located in front of two plane mirrors placed at an angle, an observer can see a superposition of images that results in a face with three eyes, called in this text a "triclops." The conditions of occurrence of such an image may seem trivial, but this is incorrect: rather, the correct interpretation of this…

Dür, Wolfgang; Heusler, Stefan – Physics Teacher, 2016
Using the simplest possible quantum system--the qubit--the fundamental concepts of quantum physics can be introduced. This highlights the common features of many different physical systems, and provides a unifying framework when teaching quantum physics at the high school or introductory level. In a previous "TPT" article and in a…

Greenslade, Thomas B., Jr. – Physics Teacher, 2016
This article is about a late 19th-century teacher of secondary school physics. I was originally interested in the apparatus that he sold. This led me to the physics books that he wrote, and these took me to his unusual ideas about ways to use laboratory time to introduce students to the phenomena of physics. More than 100 years later educational…

Lima, Fabio M. S. – Physics Teacher, 2015
When all parts of an electric circuit are at the same potential, no electric current flows and it is said to be in "equilibrium." Otherwise, a current will flow from the higher potential parts to the lower ones, as when we make contact between the plates of a charged capacitor. The resulting discharging process towards equilibrium is a…
