Journey of a River
The chapter 'Journey of a River' in the Class 5 Kerala SCERT EVS textbook (Our Wondrous World) takes students on an exciting adventure following the path of a river from its high mountain birth to its final meeting with the vast ocean. Children learn about the three main stages of a river—the youthful upper course, the gentle middle course, and the slow-moving lower course where it forms deltas. The chapter emphasizes the importance of rivers as lifelines for humans, animals, and plants, while highlighting the severe threats of water pollution and the urgent need for river conservation.
