The "Cloud Spotters and the secrets of the clouds" project, harnesses the innate curiosity and special interest that preschool children have to discover the world around them. Starting from the magical world of clouds, it engages them in interesting developmentally appropriate and high-quality learning situations, so that they adopt a positive attitude towards the scientific way of thinking and develop related skills. Its playful nature enhances children's activity, while the interdisciplinary, interdisciplinary approach to concepts combined with the use of various media, methodologies and teaching tools contributes to the all-round development of students, enhancing both their cognitive and kinesthetic abilities and the cultivation "soft skills". The structure of the project is fully compatible with the STE(A)M approach to Preschool Education, with appropriately designed activities that contribute to the achievement of the expected learning outcomes.
