Each of the three RiverXchange curriculum units features hands-on activities that reinforce one or more key water concepts known as The Big Water Questions. These questions are intentionally broad — such as Is every place in the world part of a watershed? — to encourage students to reach for deeper meaning.
Each broad question is then followed by one or more specific questions — such as What is a watershed? Where does your river start? Into what ocean does your river eventually flow? How much precipitation does your community receive each year?. The goal is for students to understand all questions and be able to formulate logical answers, but our hope is that teachers will view RiverXchange as a great opportunity to help their students become active discoverers.
