Imagine a clock that doesn’t need batteries or wires. The first clocks used big gears and weights to move hands around a circle, like the wheels on a toy car. One of them was called a water clock, which let water drip out at a steady pace so people could tell time by how much water was left. Later ones used gears and springs, making it easier for people to measure time accurately, even when they were far from a river.
Examples
- A water clock works like a slow drip of water from a bucket into another one, the more water moves, the more time passes.
- A mechanical clock with gears is like a train that keeps going around and around without stopping.
- A clock bell rings at the same time every day, just like a teacher says 'Time for recess!' in school.
