Excerpt from A Laboratory Manual in Physics: To Accompany Black and Davis' "Practical Physics for Secondary Schools" IT is now more than twenty years since we began to teach elementary physics in the laboratory and we already have many laboratory manuals. Why add another to the list? Every teacher of physics undoubtedly takes up the task of organizing his laboratory with great enthusiasm and high hopes. But sooner or later he finds that this business of teaching young people physics by means of laboratory exer cises is a very difficult problem. No amount of costly appa ratus or elaborate laboratory directions will produce that mental activity about physical phenomena that we all want to stimulate in our students.
