This paper examines the use of social media as a collaborative and engagement tool for participants in a middle school science research project conducted over a three-year period. Sky Stories is a learning initiative that employs a blend of Indigenous and Western knowledge of astronomy to engage Year 5-8 middle school students in investigative science. An integral element of the Sky Stories program is acknowledging links amongst individuals, families, and the school community and their sky stories. This enables new ways of learning, teaching and community engagement built around science and astronomy while employing culturally embedded, non-transmissive pedagogies. The Sky Stories program goals include providing opportunities for localising 'stories' in school communities, expanding teacher cultural content knowledge, and developing teachers' competence and confidence. Social media in the form of a Facebook page was used as an interactive notice board and also as a content sharing tool for school executives, teachers, and the research team. Evidence from Sky Stories participants is examined and discussed to illuminate the use of social media as a tool for showing engagement and participation.
