In police investigations, officers often only know a few details. For example, it can be that when police need to determine how fast a vehicle was driving, they only have an audio recording available to help them. In such cases, they can use the Doppler effect to determine vehicle speed. But: Can they evaluate a smartphone audio recording of ‘pass-by noise’ directly with a smartphone app?

About mascil
mascil (mathematics and science for life) was an international project (2013-2016) funded by the EU’s Seventh Research Framework Program and coordinated by Prof. Dr. Katja Maaß from the Freiburg University of Education. The aim of the 18 mascil project partners was to promote a change in the math and science teaching culture towards more research-based and problem-oriented learning and to connect stem learning to the world of work. The focus of the teaching tasks published here is on the use of smartphones in the classroom.
