Awesome decision.

I have almost the same story except it was a cross country and I was already on the way to the destination with a pvt. There was a airmet, either about to start or almost over for turbulence. I kept in touch with flight watch and approach on whether they were any pireps or any updates. No bumps at all going to the airport and the ATIS didn't have anything unusual. While on a extended final, a PA-28 reported to me(in a C-152) that there is strong turbulence on final. A few seconds past and all of a sudden I'm looking at my student holding onto me and his door, bracing himself. Out of his door about 200ft AGL was the mother earth, we were 90ish banking on final. I upper cut the yoke(seriously) and perform a go around. I decided we were done and headed back home.

Student learned not to chance anything and always fly the plane(I made sure he understood that).
