Standard teaching suggestions for student experiments on the transit method for exoplanet discovery either use relatively complex (student) laboratories1 or require expensive materials or complex settings. Simple approaches that can be easily realized in schools (especially as student-based activities) are limited to simulations2,3 or interpretation of data from database sources.4 Furthermore, ideas for implementation based on smartphones are limited to prepared kits (e.g., PocketLab) and closed-source (e.g., PASCO) devices.5,6 This paper presents an overview of these standard ways of setting up and performing a transit experiment before describing an alternative smartphone-based teaching model for exoplanet hunting. These exoplanet experiments, which are highly interesting for students7 and invite them to become young active researchers, can be performed easily and inexpensively with widely available materials and open-source software. Furthermore, we describe a method based on video recording and analysis that can support learners’ understanding of the experiment...
