The student pilot stated he performed the pre-flight sumping only the wing tanks. He also stated that he had not been shown that there were any more places to sump fuel from other than the 2 wing sumps. The instructor pilot stated he performed the pre-flight after the student sumpng the wing tanks and the fuel strainer. The instructor pilot stated that the student got a small amount of water from the lf wing. The training flight departed for the local practice area. About 40 minutes into the flight the student had finished performing steep turns as well as power on and power off stalls. The instructor pulled the carburator heat on and throttle back and told the student to perform a simulated emergency landing. From about 1000 feet the student pilot selected an empty field, turned left about 90 degrees towards the field and established a proper glide slope, descending at about 70 mph. At approximately 400 feet AGL the instructor told the student pilot to give the aircraft full power and perform a go around. The student turned the carb heat off, added full power and initiated a climb. The aircraft did not gain sufficient airspeed and continued to decsend. The student pilot stated the engine did not sound as it does for normal take-off power. At approximately 300 ft AGL the instructor took the controls and performed an emergency landing in the field. The aircraft touched down at a slightly uphill angle and rolled out through a barb wire fence and a small ditch. The instructor applied the brakes and the aircraft came to a stop. The student stated that he thinks at that point the instructor pulled the mixture and the engine stopped. Niether the student nor the instructor remember for sure whether the aircraft engine was running when the aircraft came to a stop. However, damage on the propeller blades indicate the propeller was turning at the time the aircraft struck the barb wire fence.
