     The first child appears to be in the concrete operational stage because he does not understand the abstract concept of a feather breaking glass. The way he does think about the feather breaking the glass though is logical. In his experience a feather has never been able to break glass so in his mind this hypothetical situation is no different. The second child is in the formal operational stage because she can comprehend the abstract idea of a feather breaking glass and say that in that world if someone hits glass with a feather, it will break. To teach the first child visual aid is still important because he thinks logically using concrete materials. The second child would only need to understand the implications of an abstract idea to be able to put it into use.
