Engaging activities to promote science dialogue and discussion.

Through participatory activities, we aim to engage people with science, technology, and innovation in an active manner, fostering a higher level of involvement and interaction with others. This paper presents the design process of an activity based on the perspective of public participation and the game PlayDecide, addressing the socio-environmental issue of urban solid waste management. We believe it is important to share this process as a contribution to those who design educational experiences in informal science settings.
