The secondary sector of the economy is where things are made or manufactured. Think of it like a big toy factory. In this factory, there are workers who use machines and tools to turn raw materials like wood or plastic into toys that you can play with.
For example, imagine you want to make a toy car. You start by taking some metal and plastic pieces and putting them together with a special tool to create the frame of the car. Then, you add the wheels and other parts to make it look like a real car. This is all part of the secondary sector of the economy.
Other examples of things that are made in the secondary sector include clothes, furniture, and electronics like computers and phones.
So basically, the secondary sector is all about making things that people use in their daily lives. It's like a big workshop where people work hard to create all the things we need and want.
