Narrative:

A student and I proceeded on a commercial training flight to do commercial maneuvers (chandelles and lazy 8's); and pattern work. We worked on our maneuvers and proceeded to a nearby airport for landings. We did approximately 4 normal takeoff and landings; bringing the gear up/down all 4 sessions. On the 5th pattern; we were downwind for 4L and lowered gear handle. I heard hydraulic power pack running and visually inspected mains; however we were not receiving a green light. I visually checked the mirror on my right wing and nose gear was indicating in 'up' position and gear doors were closed. We proceeded to do multiple laps around pattern; recycling gear up/down; popping circuit breaker (landing gear); and hand pumping gear down. A visual check was verified with tower as 'nose gear up/mains down.' I proceeded to read through poh as student flew and vice versa. We executed good CRM. We were also communicating between the owner and a gentleman on the ground; whom has a lot of time in a cardinal rg. He advised us to attempt some positive 'G' maneuvers on aircraft. We went out at a high altitude 3;500 ft and performed maneuvers at slow and high airspeed; attempting to dislodge nose gear and hopefully open nose gear doors. I was even putting rudder pedals left and right to try to dislodge nose gear; thinking possibly nose gear was an at an angle when it had retracted the last time. No success. So we flew back into the airport; advised them of our updated situation and they coordinated with ATC for an emergency landing at the nearby large airport. We received a squawk code and contacted ATC and proceeded to class B. I declared an emergency with ATC advising them of situation and fuel/souls onboard. We were cleared into B and proceeded final for 8R. My first pass was to come down 'mains down' and abruptly hit runway; trying to dislodge nose gear with no intent to land. I was unsuccessful. I went around and made left-closed traffic for 8R. We turned final and approximately 100 ft off ground; I shut engine down; fuel off; master off; ignition off; doors unlatched and briefed student to brace himself for impact. The mains touched down and I held the nose off as long as possible. The prop remained wind milling. As the nose hit; the prop stopped and aircraft veered slightly to the left of centerline. Once aircraft came to a stop; we both evacuated aircraft. Fire department was on sight and aircraft secured no fire.

Title: A C177 nose gear failed to extend so after several failed emergency extension maneuvers proved unsuccessful an emergency was declared and the aircraft landed with the nose gear retracted.
