The 2023 edition marked the return to pre-pandemic conditions. Nevertheless, following the good results of the ERN 2022, a mixed onsite and online program was developed to focus on Inclusion and Sustainability in scientific projects of all areas: Natural and Environmental Sciences, Physics and Chemistry, Technology, Health Sciences, Social and Human Sciences, Architecture, Arts and Design. Both the build-up and the ERN event highlighted advantages from both contexts: the online event provided the opportunity to discuss and interact directly with researchers for participants who could not visit onsite, being a factor of inclusion, while the onsite made it possible to include participatory activities. The build-up activities received 1344 onsite participants and 21 researchers were involved in those, respectively. The four onsite venues received people from North to South of Portugal, 9042 participants in total, and the online format allowed the transversal work to present a national program using the SCIEVER website and social network channels, developed by the teamwork in between Universities and partners, aiming to join a national expertise to reach the participants unable to participate onsite, 927 in total; 1929 and 77 researchers were involved onsite and online, respectively. The build-up and ERN events in the four cities included a large heterogeneity of public and private spaces where the onsite event took place (e.g. streets, gardens, squares, shops, historic buildings, and institutions), highlighting relevance of taking a large number of activities to the city streets.
The Researchers@school program was developed and activities started in the current school year with excellent acceptance and the delivery of 107 activities until December 2023, including the participation of more than 14 968 students and 194 researchers.
