The project has an attractive title starting as a story “Once upon a time...” but emphasized on “THE SEA”, which appears as a common denominator for all participants living near the sea, which we can imagine as giant labs and a learning space, geographically, politically, culturally and symbolically Europe. Students from European schools aged between 6 and 16 will be involved in documenting activities through a themed interdisciplinary approach, in order to form an ecological, social and civic behavior and increase awareness of environment problems. There will be a special attention to the inclusion of students with social and disability problems, involving them in activities compatible with their disabilities. The project is even more attractive with the activities that will stimulate their motivation to explore the sea natural attributes from a cultural – artistic perspective.
