Wheel and Axle


Imagine a world with no wheels. No cars, no bicycles, no scooters, no skateboards, no roller skates. How would you get around? How would you bring things from one place to another? Your options would be to walk, use horses and other animals, use sleds, or go by boat. Not very convenient, right?
The first wheels were probably pottery wheels, invented in Sumeria around 4000 BC. Soon after, people began making wagon wheels in Central Asia. The invention of the axle made wheels even more efficient. An axle is a rod that runs through a hole in the wheel. The axle can then be attached to a wagon, the body of a car, or other equipment.
