My class in 9th grade physical science did an activity where we burned 
steel
wool and attempted to write the equation for it.  The material with it
indicated the iron should have an oxidation number of +2.  There are other
forms of iron and oxygen combining (like various forms of rust) where iron 
has
different oxidations numbers.  The question is why  and how do they have
different oxidations numbers?
