Ludwig-Petsch, Kim; Hirth, Michael; Kuhn, Jochen – Physics Teacher, 2022
The typical sound of George Lucas' laser blaster in the "Star Wars" series is well known. What does a laser blaster in "Star Wars" sound like, and why? Here we show a simple way to produce this sound by using low-cost lab material, like a spring or a Slinky. Building on the work of Crawford, who analyzed the sound of a Slinky…

Shakur, Asif; Schwartz, Joseph – Physics Teacher, 2021
The new normal imposed on us by the COVID-19 pandemic restricted the traditional ways we would teach high school students who are eager to participate in introductory astronomy projects on our university campus. This turned out to be a blessing in disguise as we were forced to come up with creative ways to get around this obstacle. The outcome is…

Ayop, Shahrul Kadri – Physics Teacher, 2017
The iPhone 6 introduced a new feature of recording video in Slo-Mo mode at 240 fps (4.17 ms interval). This great capability when integrated with video analysis freeware such as Tracker offers in-depth exploration for physical phenomena such as collisions that occur in a very short duration of time. This article discusses one such usage in…

Galeriu, Calin; Edwards, Scott; Esper, Geoffrey – Physics Teacher, 2014
We cannot hope for a new generation of scientists and engineers if we don't let our young students take ownership of their scientific and engineering explorations, if we don't let them enjoy the hands-on cycle of design and production, and if we don't let them implant their creativity into a technologically friendly environment.…

Ballester, Jorge; Pheatt, Charles B. – Physics Teacher, 2012
The study of motion is central in physics education and has taken many forms as technology has provided numerous methods to acquire data. For example, the analysis of still or moving images is particularly effective in discussions of two-dimensional motion. Introductory laboratory measurement methods have progressed through water clocks, spark…
