Narrative:

I was operating a beechcraft sundowner as PIC giving dual instruction to a private pilot student. We were performing simulated instrument maneuvers and unusual attitude while under the simulated instrument conditions. On our return to the airport we began our descent with the intentions of making a straight in approach for approximately 6 miles to the northwest. The student was still under the hood and flying the aircraft at 500 ft per min descent towards the airport on a heading of approximately 110 and monitoring aty CTAF on 123.05. While descending through 3000 feet a correction was made by the student that turned the aircraft slightly which allowed my eye to see the cessna aircraft; tricycle gear high wing single engine; probably a 150 or 172; which had emerged from behind the door post into my vision. The cessna was slightly below our altitude and traveling from right to left; heading approximately 360; on a course that would intercept our course. I immediately took control of the aircraft from the student and began a climb with a slight left hand turn. The cessna passed directly underneath the sundowner. I continued the climb with a slight left hand turn until I regained visual contact with the cessna which was continuing on a northerly heading at a lower altitude. Radio contact was made between the 2 aircraft after the incident confirming that both pilots were ok and both flights continued on course. The weather at the time of the situation was clear skies and unlimited visibility.
