While on short final of the traffic pattern, the student pilot reduced the slip to maintain the glide path, at which time, the glider encountered a sink and descended. While in the flare over a fence, the left wing impacted a fence pole, resulting in substantial damage to the glider. The CFI stated that there was nothing mechanically wrong with the glider prior to the accident.
