Yes, indeed. Need more input. Is this some form of oxidation or precipitation experiment? Perhaps geology?
Banded Iron is a sedimentary rock formation, composed of alternating layers of iron oxides and shale or chert (both iron poor sedimentary rocks).

I have looked in our Enviromental Science text books but couldn't find anything. The EES teacher could provide no information either.
However I couldn't resist posting this picture of "banded iron" that I took at Broken Hill
