Yes, adjustable.

On a go round, after a bounce, it’s a case of get the nose down to build up speed, once the power is on, not go for an immediate climb. Looks like stalled a wing.. and ding + fire.

If you want to lose control of your aircraft, being low, slow and out of balance is a sure way of doing it.
Effects of Controls should have taught them that any application of power requires correction of pitch and yaw.

Well said Clare. Prior to doing go arounds in the circuit, I demonstrate the go around up at altitude to the student, without any initial input to control pitch and yaw. As they see the nose pointing to the heavens in the 172, their facial expression is priceless. It hits home the point !!!

Yes we do that as part of the stalling lesson, various botched go-arounds.
