arcgis desktop - Changing symbology at different scales in ArcMap?

I am using ArcMap 10 and I want to display my village parcel symbology differently at given scales. I have one idea to copy and paste same layer.

But my question is that in a single layer, is it possible to give different symbology as per the scale? e.g

Layer Name    symbol   scale
xyz            -----   100000

xyz            *****   200000
