Narrative:

Non IFR rated student was at controls; flying the ILS glide path via a simulated PAR given from instructor. Student became disoriented but did not speak up; aircraft speed increased to a near 'gear over speed'; instructor reduced power and raised nose in order to prevent the over speed. Student still had controls but again did not speak up that he was disoriented. Controls were taken by instructor when aircraft was no longer established on ILS. The decision to execute a missed approach was made simultaneously with radio call from tower advising of low altitude. Missed approach procedures were immediately executed without further incident. Aircraft landed safely on next approach. Lessons learned: do not conduct difficult training in IMC; as all attention is needed to fly the actual instrument approach without increased burden. As an instructor; I became task saturated with the training and near gear over speed and am thankful from the call from tower. In addition; a CRM discussion between pilots was conducted after the flight. 'If you feel disoriented while at the controls; speak up immediately and transfer aircraft control to the pilot not flying; if able.'
