AN APPARATUS CATALOG AS A TIME SAVER

REBECCA ANDREWSEastern High School, Washington, District of Columbia

In these days of teaching physics with a lengthy course ofstudy to be completed and little time in which to complete it,a free exchange of ideas for improving the efficiency of settingup demonstrations and laboratory experiments might be help-ful. There is presented here a method of cataloging demonstra-tions and experiments that has proved to be effective.

All demonstrations and laboratory experiments are cataloguedon 3 X5-in. cards according to the order in which they are to beset up for use during the year. The cards are placed in two3 X5-in. file boxes, one for demonstrations and one for labora-tory experiments. Each card for a demonstration has on oneside (1) a labeled drawing of the apparatus as it looks when setup, and (2) the page number of the textbook which is used asthe source of the demonstration; and on the reverse side (1) acomplete list of the apparatus required, (2) the location of theapparatus in the laboratory, and (3) special suggestions, if any,concerning the set-up. Each card for a laboratory experimenthas (1) a complete list of the apparatus used, (2) the location ofthe apparatus in the laboratory, (3) the number of pieces of eachkind needed for a class of thirty students working as partners,and (4) special suggestions, if any, concerning the set-up.

In a high school one teacher usually teaches two or morephysics courses at one time. If high standards are maintained,it is quite possible that he sets up during a period of one weekan average of nine demonstrations and sufficient laboratoryapparatus for a class of 30 students working as partners. Themethod described has been found to facilitate matters in such asituation. The original expenditure of time used in making thecards is more than compensated by the time saved later insetting up demonstrations and laboratory apparatus.
