How would you make the observation "the floor is smooth" into a more scientific observation?

I'm not completely certain of this, but when I think of being "scientific" I imagine everything being more objective and certain, as if someone needs to recreate what's happening as accurately as possible.
So for this, I might say something like what is on the floor or what the floor is made of like "the floor is made of tile" (which would be smoother than saying something like "the floor is made of cement").
