Narrative:

I was PIC instructing a student in patterns. Student landed airplane very smoothly in calm winds and was preparing for touch-and-go takeoff. As the nose wheel touched after landing; a slight shimmy developed. Half a second later; the shimmy worsened. The nose wheel and attached gear departed the aircraft. The nose of the aircraft smoothly touched the runway and slid slightly to the left of the centerline. The aircraft stopped; I turned off the master switch and opened the canopy and egressed the aircraft. Four guys from the airport walked up and helped move the aircraft off the runway. We retrieved the nose gear and made sure no other parts were left on the runway.
