Feedback please

I have done a install of Kubuntu just to see how it work, I'm a straight 
Fedora user and no desire to move to Ubuntu,
I just want to see how it works as far as SU goes.
In ubuntu , can any user type in sudo -s and get root privileges ?
For Security reasons this distro scares me.
I teach Linux at locale libraries and wanted to get a feel for ubuntu 
before I can say yea or nay.
And I don't want to go threw a bunch of hassles to track down a Ubuntu 
forum just to ask one question about a distro
that I'm not going to permanently use.

Thanks
Jim
