Narrative:

I was with an instrument student practicing landings; we did a touch and go on runway 9 at ZZZ and were going to make a full stop landing. We were instructed to make a right traffic pattern and once on the right cross wind I asked tower if I could land on runway 5 and hold short of runway 9 being that I knew there was another airplane in the pattern. Tower then cleared me to land runway 5 and hold short of runway 9. My student then made an approach to runway 5 and ended up bouncing the landing and began to porpoise. As I went to take control the aircraft the student went full throttle to go around. We then climbed to about 80-100 ft. And I looked to our left and the other aircraft was on the departure leg for runway 9 and we were on a collision course when I kept the airplane in ground affect causing us to pass slightly in front of the other aircraft and below it.
