There are two graphic organizers that can be taped or glued into the students' notebooks. The first is a four-tab flip book. The tab on the left is to be taped/glued down, and the students are to write descriptions of each sphere under the right tabs. The second graphic organizer is a chart. Students should give examples of interactions that occur between the spheres that intersect. For example, rain is a result of interaction between the atmosphere and the hydrosphere.
