Repetition best describes what took place during the class.
Explanation:
In experimental work normally repetition carried on repeatedly so that student can achieve more perfection on their assignments. Here Mr. Grayson demonstrated an experiment at beginning of class. Then in the experiment pair wise students collected data to maintain accuracy and repeat the same for recapitulation.
Repetition is the process used to follow to cope up with the new experiments. Experiment needs to be done again and again in repetition to be verified and to draw a final conclusion. In a scientific study practice gives more accuracy and perfection.
