The Covid-19 pandemic has sparked an unprecedented public debate over socio-scientific controversies, particularly regarding vaccination and social distancing measures. Despite the potential of such subjects for developing critical thinking and a sense of citizenship, the theme of controversies is still incipient in science museums. This documentary study investigates the way three science institutions have proposed online exhibits on Covid-19 on Google Arts & Culture platform and checks their potential for favoring teaching on controversial science topics. Google Arts & Culture platform was searched for Covid-19-related keywords and the filtering of the results was based on focus and organizing institutions. Three exhibits were detected, whose analysis was submitted to an inter-rater agreement (Cohen’s kappa). The results revealed the predominance of social and economic aspects that can strongly favor more scientifically progressive views of both science literacy and a socially undistorted science. On the other hand, the superficiality of political discussions on science topics, a lack of naturalization of the controversial discussions, and an excessive use of textual content were identified, thus revealing some initiatives have not explored the interactivity, multimediality, and the way dilemmas that mark the trajectory of science museums extend to online exhibits. From this perspective, we point out paths for teaching and learning socio-scientific controversies in museums.
