Is it possible to scale objects or sections of a scene independently?

I am very new to Unity and would like to know if it is possible to scale certain objects or regions within a scene without affecting anything else in the scene.

Is this possible? Maybe a short code sample?

 

...I'm not sure what you mean. If you scale a cube, you're just scaling the cube and maybe its children.

 

Yes. You simply scale the objects you want to scale. I'm don't think I've run into a game engine that doesn't behave in this way to be honest.

 

Thanks to both @Murgilod and @Ryiah for answering what must seem like a very simple question. I've not used game engines before so pardon my ignorance.
