You simply reverse the connections to it, use either a relay or an H-bridge.

Not easy with a DC motor, you would need to gear it down substanially, then have some kind of sensor to detect it's position (possibly as simple as a limit switch?).

This sort of application is probably more suited to a stepper or servo, depending what you are trying to do?.
