In March 2024, students and teachers from Menntaskólinn í Reykjavík finally visited Poland. They started the visit by learning about the culture and history of Silesia, the mining area of southern Poland, and the visit to the 19th-century Guido, hard coal mine in Zabrze, where the workshops about differences in the geological structure of Poland and Iceland continued. During the visit to the Auschwitz-Birkenau Museum, Icelanders had an opportunity to gain an understanding of a very important part of Poland’s history. Students from both schools finally met and could finish their research on their topics. After having listened to ‘The art of public speaking for a young scientist’ lecture, project participants started to summarise their work and prepare their final speeches. Divided into five teams, the pupils began working on presentations about their research problems. To compare the biodiversity of Poland and Iceland we went on a walk along educational paths in Latoszyn Zdrój – health resort. We were able to taste natural mineral water from the Pump Room in Latoszyn We also admired the beech forest in springtime. During an open day at the school in Dębica, pupils from primary schools not only had the opportunity to learn more about the project ‘Air quality research as a path to knowledge’, but also to meet our partners from the school in Reykjavik. Eighth-grade pupils listened to presentations about the implementation of the individual research groups at their stands in Polish and English. Final project materials were prepared as well. The works on design and information included in the project brochure continued. After preparing materials for the leaflets and five different project posters, chosen teachers prepared the design for the project brochure.
