Wheel Coloring Page

Nobody knows who invented the wheel, but people in Mesopotamia, in what is now Iraq, were making wheels by about 3500 BC. The first wheels we know of were probably used by potters to shape clay, and a bit later people put wheels on carts. Early wheels were heavy solid discs of wood with no spokes.

One of the oldest wooden wheels ever found was pulled out of a marsh near Ljubljana in Slovenia. It's about 5,000 years old and made of oak and ash, with a hole in the middle for the axle. That hole is the clever part, since a wheel only works when it spins around something.
