Allen, Bradley; Liu, Tongtian – Physics Teacher, 2015
Calculating the effective resistance of an electrical network is a common problem in introductory physics courses. Such calculations are typically restricted to two-dimensional networks, though even such networks can become increasingly complex, leading to several studies on their properties. Furthermore, several authors have used advanced…

Oostra, Benjamin – Physics Teacher, 2014
I present a novel way to introduce the lunar orbital eccentricity in introductory astronomy courses. The Moon is perhaps the clearest illustration of the general orbital elements such as inclination, ascending node, eccentricity, perigee, and so on. Furthermore, I like the students to discover astronomical phenomena for themselves, by means of a…

Orzel, Chad; Reich, Gary; Marr, Jonathan – Physics Teacher, 2012
The proper choice of a measurement technique that minimizes systematic and random uncertainty is an essential part of experimental physics. These issues are difficult to teach in the introductory laboratory, though. Because most experiments involve only a single measurement technique, students are often unable to make a clear distinction between…

Jumper, William D. – Physics Teacher, 2012
Many high school and introductory college physics courses make use of mousetrap car projects and competitions as a way of providing an engaging hands-on learning experience incorporating Newton's laws, conversion of potential to kinetic energy, dissipative forces, and rotational mechanics. Presented here is a simple analytical and finite element…

Hobson, Art – Physics Teacher, 2011
I'll outline suggestions for teaching elementary particle physics, often called "high energy physics," in high school or introductory college courses for non-scientists or scientists. Some presentations of this topic simply list the various particles along with their properties, with little overarching structure. Such a laundry list approach is a…

Maltese, Adam V.; Tai, Robert H.; Sadler, Philip M. – Physics Teacher, 2010
Laboratory experiences play a substantial role in most high school science courses, and many teachers believe the number of labs they offer is a measure of the quality of their curriculum. While some teachers believe labs are meant to confirm concepts taught during lectures, others feel labs should address students' everyday beliefs about the…

Hazari, Zahra; Sadler, Philip M.; Tai, Robert H. – Physics Teacher, 2008
The disparity in persistence between males and females studying physics has been a topic of concern to physics educators for decades. Overall, while female students perform as well as or better than male students, they continue to lag considerably in terms of persistence. The most significant drop in females studying physics occurs between high…

Watt, Jeanie I.; Roth, Bradley J. – Physics Teacher, 2007
This article is intended as a guide for teaching geomagnetism in a high school or university introductory physics class. Many students find this subject fascinating. Instructors, however, often have a difficult time introducing this topic at an elementary level. Suggestions will be made on how to accomplish this using three electricity and…
