World Rivers Day is today! Observed on the fourth Sunday in September, the day reminds us of the importance of rivers to humans, animals, plants, and the earth. Rivers provide hydroelectricity, water for humans, and water for crops and animals. The longest river is the Nile, but the Amazon provides the most drainage. The longest river in the United States is the Mississippi and its tributaries. Idea: Children could research rivers, make a large paper river, and write the facts on the paper river.
