The goal of this case study was to examine how a group of young children in a historically marginalized neighborhood in the northern part of the Netherlands perceived their engagement in an out-of-school, STEM community-based program aiming to enhance young children's interest and self-identification with science. We collected data through semi-structured interviews with eight purposefully selected children and analyzed those through a constant comparative approach and with the use of open coding strategies. The findings revealed specific aspects of the design of the program that were perceived as motivating and engaging: the integrated multidisciplinary approach to exploring scientific concepts and opportunities for active engagement and personally relevant science experimentation. The findings are offered alongside a set of recommendations for the design of out-of-school, community-based programs that aim to support young children's engagement with science.
