Do note that on, at least, mobile Chrome, the Chrome "omnibox" is actually rendered as the Google search page's search box. Typing addresses "into Google" is how you get the browser to navigate to them. If that's the only browser you've ever used, it would be quite a surprise to find that on the school computers, the Google search box is just a search box, and there's another box up at the top of the browser window you have to use for URL entry instead.
