Describe what life was like in SUMER both before and after wheel

All civilizations create new advances in technology.  Ancient Sumer had several technological creations.  The most important, and popular was the wheel.  The wheel has been dated back to as early as 3500 B.C.E.  At first, wheels were used as a surface for shaping clay into pots.  These wheels spun flat side up, and on a axle.  Soon after that, the Sumerians discovered that the wheel could be used a different way.  They flipped the pottery wheels on their edges, and found out that they could be used for rolling things forward.  With this new information, Sumerians, created wheeled carts for farmers, and chariots for the army.  They came up with a way of building wheels by clamping pieces of wood together.

Before the wheel, Sumerians had to drag their goods on flat- bottomed carts called sledges.  The sledges often got stuck in the mud, and couldn’t carry heavy loads of supplies.  So, wheeled carts made transportation much easier.
