At about 1553 eastern time, a Cessna 150K ditched into the water at the end of the runway after an aborted landing at Everglades Airpark. The flight instructor received minor injuries and the student received serious injuries. The instructor stated the student was on a stable approach to runway 33 but bounced the landing. The student then advanced the power for a go-around and the airplane banked to the left. The instructor took control and banked the airplane back toward the runway centerline. The airplane struck the runway edge lights on the right side of the runway, but the instructor continued the go-around. The airplane was airborne by the end of the runway but could not climb. To avoid trees, the instructor ditched the airplane in the water.
