The wheel is like a magic circle that lets things roll instead of slide. Before the wheel, people pushed heavy rocks and carts with their feet or used logs as rollers. When they added wheels, it was easier to move things, and that helped them build bigger cities and travel farther.
Examples
- A child pushes a toy cart with wheels across the floor and finds it much easier than pushing a box without wheels.
- A farmer uses a wheel-powered cart to bring vegetables from the fields to the market instead of walking all the way.
- A group of people uses logs as rollers, but when they put them on a cart, it rolls smoothly.
