Pick an element in the HTML panel of the developer tools and type this in the console
$0 is a reference to the selected DOM node in the elements tab, so by doing this you get the selected DOM node scope printed out in the console
Also you could assign this to a var for future reference like
var scope = angular.element($0).scope();
Then you could do, scope.yourModelName to check values.
$0-$4 stand for the 5 DOM nodes that you recently selected. $5 will be undefined.
