Spare part

Okay kiddo, so you know how when a toy or machine is broken, we can fix it by replacing the broken piece with a new one? Well, that new piece is called a spare part.

Let’s say you have a toy robot that has arms and legs that can move, but one day the arm falls off and won’t stay in place. That’s a broken toy, right? But don’t worry, we can fix it by getting a spare part for that robot arm.

Basically, a spare part is a brand-new piece that is exactly the same as the broken or missing one, so it can replace it and make the toy or machine work again. It’s like having a backup piece, just in case we need it.

Spare parts can be found for all sorts of things, like bikes, cars, phones, computers, and even airplanes! They’re really important because they can save us money and time that we’d otherwise spend on buying a brand-new toy or machine. Plus, we get to learn how to fix things ourselves and become little engineers!
