Narrative:

This event occurred during a training flight. My student pilot and I were doing touch and go's. We were in the process of completing our 5th touch and go while the nosewheel tire became flat and the prop strike occurred. The weather was clear; visibility greater than 10SM and I recall the wind as last reported being 140 @ 6KTs. On this approach we had a nice stabilized descent; airspeed was under control and we were right on glide path. I remember saying to my other student pilot; who was observing from the back seat; that 'this is perfect and exactly how it should be every time.' as we approached the threshold my student brought the power back to idle and started his flare. When the aircraft was over the centerline and about 5-10 feet off the ground my student thought he was slightly high so he pitched the nose down aggressively (we were actually slightly nose low at this point). I quickly started to increase the backpressure but before I could arrest the rate of descent the nosewheel struck the ground and the aircraft bounced up. At that time I decided it would be best to execute a go-around instead of trying to save the landing; so I added full power and continued climbing out. After we had a stabilized climb I gave the controls back to my student for one last trip around the pattern. This time when we came in for landing we executed a perfect touchdown. As we rolled down the runway the nosewheel began to shake and vibrate. I was able to taxi clear of the runway and pull on to the taxiway where I was advised by ground control to shut the aircraft down. I shut the aircraft down and got out to expect the damage. Just as I thought we had a flat nosewheel tire. Although upon further inspection I also noticed that both propeller tips had very light scraping on the outside edges. Ground units helped tow the aircraft and give us a lift to the transient parking. In retrospect I believe that the only way this could have been prevented was if I started pitching back on the controls at the same time my student pitched down. Due to the proximity of the aircraft to the runway surface and the force at which my student pilot pitched down; it would have been near impossible to prevent this from occurring.
