Citizen science projects with a focus on involving educational institutions aim at the participation of pupils and teachers in scientific research. In the present study, we scrutinized the cultural and inclusive quality of the funded projects “Sparkling Science” by examining whether aspects of inclusion were taken into account in the various projects with focus on natural science topics (N=33), funded by the program in the frame of two calls for proposals (i.e. 5th call 2012 - 2015 and 6th call 2017 - 2019). This article is intended to stimulate discussion on how to take up the central idea of inclusion (also) in the sense of a democratization of science.
