In this activity children investigate healthy rivers. Younger children experiment with how various objects float or sink. Older children are asked to imagine that a large tub of water is a river and watch as various materials (contaminants) are added to the river and affect the health of the river. Children are asked to make assessments about what is a healthy river and how we can keep our rivers healthy.
