Narrative:

I had a student doing normal, short, and soft field lndgs from the right seat. Abeam the numbers he did a gump check (gas on, undercarriage mixture, and propeller). I noticed 3 green lights on gear. We were cleared for touch and go, then tower told us to extend due to traffic on right base. The student turned base and then final. All of a sudden I heard metal rubbing. The airplane then slid down the runway on it's belly. Nose gear doors were in open position. The only damage to airplane was propeller damage.
