If the earth's surface is 70% water, in what ways are this body of water subdivided in relation to life?
This lesson examines aquatic habitats. How do organisms survive and interact? What factors limit or promote life? How are oceans different from rivers from lakes? There's a lot to this lesson, but it attempts to distill many diverse factors into focus and expose students to an incredibly complex and diverse set of habitats that all share the common theme of "water."
