Imagine you're trying to fix something, like a puzzle. But instead of using your hands, you have a really cool tool called a fixture! A fixture is a special tool that helps you hold something in place while you work on it, kind of like a helping hand.
For example, imagine you're trying to drill a hole in a piece of wood. If you just hold the wood with your hand, it might move around and you could accidentally drill the hole in the wrong spot. But if you use a fixture, it will hold the wood still while you drill, so you don't make any mistakes.
There are all kinds of fixtures for different kinds of jobs. Some are big and complex, like the ones they use in factories to assemble cars. Others are smaller and simpler, like the clamp your dad might use to hold a piece of wood while he saws it.
The important thing to know about fixtures is that they're really handy tools that help you work on things more easily and safely. So if you ever need to fix something, a fixture might be just the thing to help you get the job done right!
