Narrative:

I was flying with my student in a cessna 152. We had been to the practice area doing maneuvers. Upon our return I was told they were using runway 21 because the wind was calm. We entered the downwind and we did the procedures to set up for a power off landing which is what I teach for landing at this airport. The airport has a short; narrow runway. My student had a nice glide on final and his flare was good but we started floating and went past the 'yellow line'; which is the go-around runway midpoint at this airport. We had not touched down and I said; 'my airplane' and gave it full power; carburetor heat in; flaps up to 10 degrees. The airplane was not climbing for maybe 200 feet down the runway and I started to lower the nose slightly and headed to the right. I was past the road at the end of the runway when I heard a bang and knew the left wheel had hit a tall marker on the south side of the road. The marker is approximately 20 feet high. I asked my student to see if the wheel was all right and he said it looked fine to him. I called back to the airport and asked them to look at the wheel when I made a low pass; which they did and said it looked O.K. I then went around and came back in and landed the airplane. I taxied the airplane to the maintenance hangar where I got out of the airplane and looked at the aircraft. The left wheel seemed fine but on further inspection I noticed a dent in the right leading edge of the horizontal stabilizer. It was the size of a quarter or 50 cent piece and approximately 1/4' deep. The mechanic banged both hands against the area and the dent popped out some. No other damage was seen other than normal for a rental airplane.

Title: An extended float on an attempted landing at a short runway caused the instructor to assume control from the student and make a go-around. While doing so they struck a 'marker' on the ground beyond the airport property. Minor damage resulted.
