Horse buck for a lot of reasons, from saddle pain to just wanting to play instead of work. Try lots of practice involving up/down transitions to get/keep the horse focused, do not ever give in, and end on a good note, even if it brief. Repeat and repeat more. With consistency, I haven't seen a horse yet that didn't eventually learn that while being ridden, it's work, not play time.
As far as avoiding the buck, make sure you keep the head up at the first sign the head is going down...it's very hard for a horse to buck when its head is up.
Good luck and be safe.
