Autumn is one of the most unusual periods in the cycle of natural changes. It not only delights with a palette of colors – from yellow, through red to subdued brown, but also encourages us to explore the secrets of the surrounding nature. It is also a time to awaken children's creativity, cognitive curiosity, sensitivity in contact with nature. During the implementation of the project activities, children, playing the role of explorer and researcher, will explore the secrets of the surrounding nature.
