Sobhanzadeh, Mandana; Zizler, Peter – Physics Teacher, 2021
In this paper, we present a selection methodology in the physics laboratory that lowers student anxiety and is beneficial to the instructors as well. At Mount Royal University, the traditional laboratory experimental exercises were replaced by a new style of laboratory called labatorials. In our previous research work, we found that labatorials…

Gainer, Alexandre; Waxman, Michael – Physics Teacher, 2021
Friction is one of the most important forces studied in classical mechanics, and still is the subject of pedagogical literature. In a small series of problems stated below, we consider a particle sliding down a curve under the actions of gravity and kinetic friction. Unlike many of the referenced sources, we neglect the centripetal force arising…

Mungan, Carl E. – Physics Teacher, 2021
Ampère's law is presented in introductory physics as a relation between the line integral of the magnetic field around a closed loop and the net current crossing any open surface spanning that loop. By allowing the surface to pass between the plates of a charging parallel-plate capacitor, Maxwell realized that this law is incomplete and introduced…

Forringer, Edward – Physics Teacher, 2021
When authoring physics problems, professors may develop an intuition for how much information they need to provide such that the problem has a unique answer and is not over constrained. It is an open question as to whether using intuition leads to a sufficiently broad range of problems. In this paper we discuss a systematic way of authoring…

Bellavia, Landon – Physics Teacher, 2021
In traditional introductory physics courses, concepts of distance, displacement, speed, velocity, scalars, and vectors are generally taught near the beginning of the course. However, students often contend with preexisting notions, such as the idea that speed and velocity are synonyms, which present some of the first conceptual hurdles that they…

Greenslade, Thomas B., Jr. – Physics Teacher, 2021
Look along the shelves holding your laboratory apparatus and into the demo-prep room, and you will find apparatus by "Cenco" and "The Central Scientific Company" sharing space with your new PASCO equipment. At the 1989 AAPT meeting in San Luis Obispo I was asked to talk about Cenco in honor of one of its long-term employers and…

Kim, Sungki; Paik, Seoung-Hey – Physics Teacher, 2021
The floating and sinking phenomenon related to buoyant force can readily be observed in everyday life and easily demonstrated to young students. However, many students believe that the buoyant force is determined by the object's attributes, such as the shape (e.g., ship) or material (e.g., wood). As a result, students find it challenging to…

Bates, Alan – Physics Teacher, 2021
The law of conservation of momentum can be applied to a wide range of processes whether it is the collision of subatomic particles, rocket propulsion, or the recoil of a cannon. In this experiment two technologies, the Arduino microcontroller and a PASCO smart cart, are used to create a movable rubber band launcher. The Arduino microcontroller is…

Hootman, Stacy A.; Pickett, Cory – Physics Teacher, 2021
To help engage non-physics majors in a General Physics II (Electricity & Magnetism) course at the University of Indianapolis, students used their smartphones to detect magnetic fields on campus in a semester-long data collection project. This paper discusses details about the design of the project, previous studies that utilize smartphones for…

Seeley, Lane; Gray, Kara; Robertson, Amy D. – Physics Teacher, 2021
The Next Generation Science Standards lay out a model of energy that locates energy within objects and fields, and tracks energy as it transfers between these objects and transforms between forms of energy while always being conserved. This model of energy pervades much of modern science and represents a foundational, cross-cutting concept for…

Gróf, Andrea – Physics Teacher, 2021
Owing to the presence of the Coriolis effect, the rotation of Earth has a multitude of surprising consequences that make the mechanics of the atmosphere or the oceans different from that of a fluid in a container. Since the Coriolis effect also captures the imagination of screenwriters, contributing to the continual exposure of students to bogus…

Gössling, Alexander; Becker, Sebastian; Kuhn, Jochen – Physics Teacher, 2021
Supersonic free-fall jumps are excellent examples of kinematics in the context of drag. They have attracted a lot of media, public, and scientific interest. In 2012, Felix Baumgartner jumped from a height of approximately 38.969 km. During his flight he reached a top speed of 373 m/s, becoming the first human to travel faster than the speed of…

Martínez, Alexuan; Nieves, Christian; Rúa, Armando – Physics Teacher, 2021
Many physics projects recently designed for high school teachers use Arduino as the main tool for managing sensors and data acquisition. This is a low-cost integrated development environment programmed with a simplified version of the C++ language. In comparison, the Raspberry Pi 3 platform, which also allows for the design of physics projects,…

Dumar, John – Physics Teacher, 2021
When our school implemented AP Physics 1, I wanted to include a project that would extend over time, use more advanced data analysis, and teach students about handling experimental error. Using a donated 5-inch Newtonian telescope and an entry-level digital camera, the students gathered data from digital images of the four Galilean moons, Io,…

Carter, Ashley R. – Physics Teacher, 2021
Introductory lab courses have been a staple of the physics curriculum for over 100 years. Yet these courses are now poised for change as recent research shows that they do not meet a frequent goal of enhancing student understanding of lecture content. In thinking about how to move forward, a look back at experiment courses in history seems wise.…
