graphs. A pie graph will compare salt water and fresh water on Earth. A bar
graph will illustrate the sources of freshwater on Earth.
Step 2: Students use the three illustrations of the hydrologic cycle, how
plants interact with the water cycle, and the water table to create a labeled
diagram or graphic organizer of the water cycle.
Step 3: To incorporate literacy into the assignment, each student writes in

that is given to them before they write. The rubric contains key vocabulary
words that must be present in the writing assignment.
