The student pilot was flying solo in the traffic pattern and had landed with the intention of performing a touch-and-go. During the takeoff, the airplane "veered heavily to the left." The student pilot attempted to correct the veer without success. The student pilot elected to land the airplane in the grass; the airplane bounced twice and then nosed over resulting in substantial damage to the right wing and rudder. The student pilot stated that there were no mechanical anomalies with the airplane that would have precluded normal operations. The student pilot did not maintain directional control of the airplane during the touch-and-go.
