Depending on the level of students, the technical terminology could be used. The simple diagrams leave out such terms as transpiration. The more comprehensive ones include a plethora of terminology. Then ask a few volunteers to tell why they rated certain ones better than others. The diagrams help us visualize and understand the hydrologic cycle.
Some diagrams are more helpful than others.
Grades will be based on neatness, completeness, and accuracy. Completeness can reflect the level of detail originally used, labels, arrows, spot illustrations, the inclusion of the sun, groundwater, directions, title, etc. Make a picture book in the shape of a water drop. Each page reflects an event in the history of that drop. Captions should add detail and creativity.
