During the project our students observed weather in their countries. They made weather calendars and presented other students what's the weather like in particular countries. We watched partners' weather projects and discussed where is the best and where is the worse weather in Europe? They discoverd that in some south countries autumn is rather warm but in the  north the weather is more often changable. One day is sunny, but one day is cold and windy.
