The “Play and Learn… in Nature” Project aims to stimulate the development of children's potential with games and outdoor activities, allowing children to explore their full potential, acquire healthy lifestyle habits and respect Nature. In the official documents issued by the European Union and the UN, recommendations have been made for the child to have the right to a quality education, which guarantees the possibility of developing in all its domains and which promotes the child's respect for the environment, as mentioned in the Convention on the Rights of the Child, adopted by the United Nations General Assembly. These premises are reinforced in the Curricular Guidelines for Pre-School Education (2016), which recommend to educators the importance of a diversified quality learning, centered in different educational contexts, not just based on the activity room, due to the possibility develop various forms of social interaction and contact and exploration of natural materials ”, valuing contact with living beings and other elements of nature, resulting in very stimulating experiences for children, developing“ awareness of the importance of each one's role in preservation of the environment and natural resources. ” In order to further strengthen the importance of nature in the lives of children, we have been sustained by the Sustainable Development Goals (SDGs), which we have disseminated in our educational communities, and which, together, we intend to make our contribution. Although we have children who are interested in nature, like to explore, learn about plants and animals, and have, in our schools, the experience of playing outdoors, we realize that there is a need to put in place an action plan that develop environmental awareness in children and their families, As additional objectives we intend: To have more informed, trained and attentive professionals to environmental issues; involve families and local associations in a common focus, valuing learning with environmental practices; encourage staff to improve their English language communication and professional skills; share new methodologies with European partners and create own resources. For that, we brought together schools from Serbia, Slovenia, Croatia, Poland and Portugal to join forces and complete the project.
