The project will include acquaintance activities between the children, such as activities aimed to the presentation of the school buildings and their daily life at school, through the exchange of material. There will also be a systematic daily and monthly recording of the weather in all schools participating, so as to make predictions, to compare the weather in the different regions, to draw and present the relevant conclusions at the end of the school year. Emphasis is given on the use of new technologies for the creation of exchange material (e-mail, videos, photos, presentations).
