By participating in and contributing to one of the largest STEM campaigns in the world the 2021 STEM Discovery Campaign, Alytus Jotvingiai Gymnasium, started implementing STEM activities, indicating them on the map of STEM discovery campaign. Through its activities, we will seek to participate in the European Blue School Network, which is set up at the initiative of the European Commission and partners with DG Mare and EU4Ocean. The STEM discovery campaign focuses on two very important themes: sustainability and citizenship. Our gymnasium teachers take action by organising activities that increase students’ understanding of a Healthy and Clean Ocean, highlighting the relevant skills that students will need in the near future.
