Abstract

The article in the Physics Teacher journal discusses using a smartphone barometer app to measure the excess pressure of soap bubbles. By conducting experiments with a smartphone barometer, plastic bag, and drinking straws, students can explore the relationship between bubble radius and excess pressure. The study demonstrates that smartphone barometers have a good pressure resolution, allowing for accurate measurements of pressure differences inside and outside soap bubbles. The research provides a practical and engaging way for students to investigate physics concepts and conduct hypothesis tests in a laboratory setting. [Extracted from the article]
