Global warming is a phenomenon that affects us every day. It is not only about the human species, but about the entire planet: plants, animals, glaciers, water resources, food, etc. What are the causes? What are the solutions? We explain the phenomenon to children, involve them in practical activities, guide them to look for even more information. If we do not understand and act, the future will not be a good one. On March 17 and 19, 2021, the teams participated in two seminars on global climate warming. There were interesting activities, we had something to learn. The activities were organized by the teams from Turkey (17.03.2021) and from Italy (19.03.2021). Thank you! At kahoot, our student, Raluca, got the best score. Congratulations to all participants!
