It uses the arts extensively to convey human uses and impacts. Activity directions do not always make the connection between the specific activity and the overall objective of the curriculum.

Materials use a unique strategy to tie all the activity concepts together.
Students write a story, in sections, as the unit proceeds.
The teacher or leader provides the story outline, a trip through the waste water system by students shrunk to one one-thousandth of their size. The students provide details and adventures for each step. Materials do not indicate which activities relate to which part of the story. Teachers will need to select activities most relevant to the aspects of the water pollution story they wish to emphasize.
