Narrative:
Turning final I requested flaps one and then five. As we rolled out on final and were cleared for approach; I requested flaps 10. When we intercepted localizer and were about to intercept glideslope; I called for gear down. The first officer noticed flaps were still indicating one. I took a quick look at the flap handle; aircraft configuration and distance to airport then decided to go around. First officer started working with the QRH and I asked the check airman riding the jumpseat to notify the flight attendants of our problem and make a PA announcement to the passengers.we asked to be taken out of the traffic area so we could work on the problem and declared an emergency. We worked through the check list and it took us to extending the flaps by alternate extension procedures. Unfortunately we were only able to get the flaps to slightly beyond 5 and they stopped there. We completed the alternate flap extension checklist; the descent/approach checklist and landing checklists then requested to be turned in for approach and landing. We completed the landing without further problems. Rescue equipment was standing by but did not need to be used.
