A visitor from outer space is coming to Earth and needs to have information about our planet. Our students will show him that our planet is rich in diversities both in cultures and nature. Activities will be planned over three main topics: diversity among us (ourselves, our schools, our countries), diversity in culture (our languages, alphabets, recipes, houses, etc.) and diversity in nature (biodiversity) and will last over the school year. Six schools from Italy, France, Poland and Greece will be part of the project which was inspired by the reading of the book “If you come to Earth” by Sophie Blackall.
