Soil scientists gain experience with an infiltrometer can to determine the infiltration rates at different locations on campus. If you are using the entire unit, the class has already analyzed water flow and soil types, so they should have eliminated several possible locations for setting up a rain garden. The lesson can, however, stand alone as a lesson on soil characteristics. This is an activity that would be skipped over if you are planning a rain garden with primary classes.
