Even among the sciences, physics stands out as an unusually White- and male-dominated field. The American Institute of Physics (AIP) reports that only 19% of physics faculty are women, and less than 6% of physics faculty are African American or Hispanic. Particularly for female students, the transition from high school to a college major in…

A laboratory experiment often performed in an introductory electricity and magnetism course involves the mapping of equipotential lines on a conductive sheet between two objects at different potentials. In this article, we describe how we have expanded this experiment so that it can be used to illustrate the electrostatic properties of conductors.…

Values for physical constants are commonly given as abstractions without building strong intuition, and are too often utilized solely in the pursuit of more easily conceptualized properties. The goal of this experiment is to remove the obscurity behind Young's modulus by exploring the phenomena associated with it--namely, the frequency of a…

An improvement of the experiment with a driven pendulum is proposed: during a run, the phase shift between the driving force and displacement is continuously displayed vs. frequency. The method of phase measurements is taken from the lock-in detection technique. Using the new PASCO data acquisition system, the measurements in a frequency range…

With any piece of technology, there exists a learning curve where students need time to adjust to the ways in which the device works. If you struggle with having enough time for lab, it may be advantageous to have students learn how to operate one set of equipment and use that equipment as much as possible. In this article a unique application for…

A single laboratory exercise in introductory physics that includes a bit of calculus, a little programming, some breadboard wiring, and making mathematical connections between motion, net force, and power provides a nice STEM experience for students. If you can add in a biomechanics component you hopefully have something that overall can be an…

Many introductory physics courses begin with the teaching of motion and kinematics. This naturally leads to the use of constant acceleration equations to solve various problems involving common motions (free fall being a notable example). Students can sometimes get the impression that these equations are the only thing they need to remember in…

Physics instructors recognize the value of kinesthetic experience in learning fundamental physics concepts. We describe a kinesthetic experiment appropriate for both college and high school physics students. The experiment helps students achieve an intuitive understanding of Newton's second law in a way they find quite enjoyable. It was devised by…

Physics students have traditionally prepared many kinds of reports-- laboratory, activity, project, and even book or article reports. Smartphones and YouTube videos are familiar cultural objects to current students, and our students use smartphone cameras to include photographs of apparatus, phenomena, hand-sketched figures, graphs, and…

The author, Greg DeLisi, a professor at John Carroll University, is always looking for ways to bring current events into his introductory physics classroom or laboratory. He is especially interested in finding examples where basic principles of physics can be used to cast skepticism on assertions made by celebrities, politicians, or professional…

Introducing new physics phenomena through inquiry labs has been a staple of the successful physics teacher for years. Introducing new vocabulary through lab work, however, is less common. This paper offers an example of a simple and short lab that does just that, and one that I have found to be quite useful in my college prep physics courses to…

"Periscope" is a set of lessons to support learning assistants, teaching assistants, and faculty in learning to notice and interpret classroom events the way an accomplished teacher does. "Periscope" lessons are centered on video episodes from a variety of best-practices university physics classrooms. By observing, discussing,…

This is a story about discovering a bias that affected participation grades in my Introductory Physics for Life Sciences class. My expectation, that actively engaged students tended to talk frequently in my presence as their teaching assistant, would have erased two students' outstanding performances if not for the participation grade policies…

Students are often introduced to optics in their middle school years. The initial topics that are introduced through their lessons are laws of reflection and refraction of light. In the law of reflection, students do not often question why the angle of incidence is equal to the angle of reflection and why a light ray should follow this specific…

In this work, an easy-to-set-up demonstration about electromagnetic induction is presented, where a simple toy electric motor is transformed into a musical instrument. With this creative way to mix physics and music, it is expected to engage and motivate students to learn about the basic concepts of electromagnetism.
