Mungan, Carl E. – Physics Teacher, 2018
Consider a chain of length L that hangs in a U shape with end A fixed to a rigid support and free end E released from rest starting from the same initial height (call it y = 0) as A. Figure 1 sketches the chain after end E has fallen a distance y. Points O and A are assumed to be close enough to each other and the chain flexible enough that the…

Rohr, James; Wang, Si-Yin; Nesterenko, Vitali F. – Physics Teacher, 2018
Our motivation for this article is for students to realize that opportunities for discovery are all around them. Discoveries that can still puzzle present day researchers. Here we explore an observation by a middle school student concerning the production of what appears to be water-like "ripples" produced in aluminum foil when placed…

Harris, R. W. – Physics Teacher, 2018
We did not have laptops or computer networks in schools in 1968, when I started teaching physics. When classroom computers became available, followed by the internet, I greeted them as great educational tools. I developed my own website in order to provide reference material and assignments for my students. I found that online assignments were…

LoPresto, Michael C. – Physics Teacher, 2018
In a recent "AstroNote," I described a simple exercise on the mass-luminosity relation for main sequence stars as an example of exposing students in a general education science course of lower mathematical level to the use of quantitative skills such as collecting and analyzing data. Here I present another attempt at a meaningful…

Milner-Bolotin, Marina – Physics Teacher, 2018
Effective physics teaching requires extensive knowledge of physics, relevant pedagogies, and modern educational technologies that can support student learning. Acquiring this knowledge is a challenging task, considering how fast modern technologies and expectations of student learning outcomes and of teaching practices are changing Therefore…

Bülbül, Mustafa Sahin – Physics Teacher, 2018
This article focuses on an illusion due to our perceptions regarding competing coordinate systems or frames. I share an interesting anecdote and then explain aspects of its origin, referencing other similar illusions in the literature. Although it is difficult to experience the phenomenon without visiting the hill, I have some suggestions to…

Greenman, Mark D.; Duffy, Andrew – Physics Teacher, 2018
Economically disadvantaged and underrepresented high school students in many urban, rural, and small suburban communities don't have access to Advanced Placement® (AP®) courses either because of a lack of trained teachers, limited or no AP program, or a school history of low participation. Physics is often a "gate keeper" course to entry…

Huggins, Elisha – Physics Teacher, 2018
Consider the fall of the apple that, by legend, hit Newton on the head. Instead of using this to introduce Newton's law of gravity, we will discuss the point of view that the fall of the apple was caused by a minuscule curvature of spacetime in the region surrounding Newton and the apple tree. We will calculate this curvature using concepts and…

Dake, L. S.; Ribaudo, J.; Day, L. H. – Physics Teacher, 2018
In a small physics department it can be difficult to develop and maintain an environment that engages students of all levels, and encourages and facilitates student growth in curricular and co-curricular experiences. This difficulty can be amplified when the number of physics majors is small, especially with fewer than 15-20 majors in the program.…

Morgan, David L. – Physics Teacher, 2018
There are many reasons for exposing physics students to primary source material in the sciences. These works can illuminate the history of science and give students a more vivid picture of the development of physics than most textbooks attempt to provide. They can also serve as pedagogical tools for exploring the misconceptions and "wrong…

Lancor, Rachael; Lancor, Brian – Physics Teacher, 2018
Project-based learning has been shown to be an effective pedagogical strategy that motivates students and thus promotes learning. In this article we describe a project-based unit centered on the physics of solar cookers (Fig. 1 and 3). Our goal was to elevate the solar cooker from a summer camp activity to a college-level project that could be…

Goh, Ker Liang – Physics Teacher, 2018
Archimedes' principle states the buoyant force is equal to the weight of fluid displaced by the object. In this work, we will develop this principle using energy considerations.

de Jesus, V. L. B.; Sasaki, D. G. G. – Physics Teacher, 2018
Nowadays, in almost any country in the world, it is difficult to find a young person who has never played with, seen, or heard of the most famous toy in 2017: the fidget spinner. According to Wikipedia: "The fidget spinner is a toy that consists of a ball-bearing in the center of a multi-lobed flat structure made from metal or plastic…

Liang, Qingsheng; Wei, Yajun – Physics Teacher, 2018
"How does an aircraft fly?" is one of the most frequently asked science questions by young pupils. The lift on airplane wings also makes a great example of the application of the Bernoulli principle while teaching fluid mechanics in introductory physics and engineering courses. The topic is of great interest and is therefore covered in…

Suits, B. H. – Physics Teacher, 2018
The peak position of the spectral density for blackbody radiation is given by the Wien displacement law. Within introductory physics materials it is often stated, or implied through example, that the color of the light emitted from a blackbody, such as the Sun, can be ascertained from knowledge of the position of that peak in the spectral density.…
