Education in chemistry occurs best when the three components of the 'Triangle'-anexperiment, a description of the experiment, and an explanation of the experiment-are at thesame place at the same time. Lectures in a main chemistry building on Mondays, Wednesdays,and Fridays and labs in another building on Tuesdays or Thursdays are not the same experience.
