Abstract

We created an introductory physics activity for undergrad students consisting in measuring by different methods the same physical quantity. It allows to confront students with questions of uncertainty, precision, and model versus theory. The aim was to measure the height of a building using only a smartphone and everyday low-cost equipment. We designed 61 methods to do so and tested most of them. These methods can be implemented in various pedagogical scenarios, engaging students into a concrete task, outside of the lab, easily set up at almost zero cost.
