Stephens, Jeff; Bostjancic, Melissa; Koskulitz, Tara – Physics Teacher, 2019
The use of video analysis for the study of motion and forces is well established in the worlds of physics and biomechanics. The issue of parallax error, sometimes referred to as perspective error or scaling error, when videotaping a moving object is known, and the experimenter is often counseled to be "far away." However, "far…

Thy, Savrin; Iwayama, Tsutomu – Physics Education, 2021
This paper presents a thorough method for studying the interference of water waves. The study aimed: (a) to demonstrate the interaction of two coherent waves, which creates interference patterns, and (b) to analyse the interference patterns. Three main tools were employed: a simplified ripple tank to experiment, a smartphone camera to record the…

Coleman, Aaron B.; Lam, Diane P.; Soowal, Lara N. – Biochemistry and Molecular Biology Education, 2015
Gaining an understanding of how science works is central to an undergraduate education in biology and biochemistry. The reasoning required to design or interpret experiments that ask specific questions does not come naturally, and is an essential part of the science process skills that must be learned for an understanding of how scientists conduct…
