This is the fourth volume in the series. It covers topics such as the formation of oil (geographical knowledge), how dolphins sleep (zoological knowledge), plant sexes (botanical knowledge), and the human sense of taste (knowledge about humans). Each day includes a short science question, elaborating on a specific point of knowledge. These points are closely connected to real-life situations, allowing young readers to go beyond the textbook and use real-world examples to verify their understanding while exploring nature.
