The 1^st study visit of the project took place at Ioannina, Greece in February 2020, alongside with the Kick-off meeting. The project partners that attended the study visit had the opportunity to meet the Dean of University of Ioannina and exchange views, while skype contact with a member of the European Parliament gave them the opportunity to talk about the Green Deal-Pillars (economics and investment on education) EU project, and explore possibilities for synergies with the 21 TS project. An educational visit to the 1^st Model Experimental School of Ioannina took place, where participants took place in Maths and Science Education sessions.
