Students and their teachers from North Macedonia, Turkiye, Estonia and Lithuania shared knowledge and ideas during an online meeting: “Water”, “Plants”, “Animals”, “Recycling”. Children from Turkiye presented the water cycle model. Estonian students and their teachers presented insectivorous plant and told how to make it out of paper. Children from North Macedonia created animals from secondary raw materials and showed a short performance “World of Animals”. Children from Lithuania shared their knowledge about waste sorting, showed what colors symbolize different materials. We are glad that our students shared their experiences with friends from different countries and learned new things about these nature-related topics.
