yes, it works just fine in Mathematica 9, returning exactly the same 
result it would in any version from 6 onward -- namely, Null (which 
produces no displayed output).

Consult the Documentation Center for Do:

  Unless an explicit Return is used, the value returned by Do is Null.


As shown in the docs, the usual way to have each of the suggested table 
of values actually displayed is to use Print:

  Do[Print[ Plot[x^2 + c, {x, -2, 2}] ], {c, -1, 1, 0.2}]

Or, perhaps more perspicuously:

  Do[Plot[x^2 + c, {x, -2, 2}] // Print, {c, -1, 1, 0.2}]
