Narrative:

During a training flight; my student and I were conducting stop and go landings. After takeoff we retracted the landing gear and upon full retraction; I simulated an engine failure by reducing the throttle to idle. My student put the gear handle in the down position lowering the landing gear and proceeded to carry out the rest of the emergency procedures as outlined in the emergency checklist. After completing the emergency procedures; I gave him back his engine and told him to execute a missed procedure. Upon attaining a positive rate of climb the student raised the gear. When the gear reached full retraction; we heard a noise from the back of the airplane. I told my student we were going back to the airport to make a precautionary landing. Upon lowering the landing gear handle; I discovered that there was no green light giving us a positive gear down indication and no wheel visible out my window. We spent about an hour and a half after that burning off fuel; discussing our options; troubleshooting using the gear failure checklist; and going through all of the emergency checklist items for a gear up landing. Recycling the landing gear several times did not remedy the situation. We also tried using the emergency gear pump to lower the gear. This did not work either. We called airport operations to get emergency crews on the scene. After discussing our options with each other and ground support; we made the decision to do several practices approaches to get ready for a gear up landing on the runway.

Title: A C-172RG landing gear did not extend for landing so the instructor and student burned fuel down; completed all checklists and made a successful gear up landing.
