This set of laboratory exercises in general science is an outgrowth of courses given by the author in methods of teaching secondary school sciences. Many of the exercises have enough material for more than one lesson and should be subdivided to suit teaching conditions. The emphasis placed in these lessons upon the interests of the individual, in both their personal and their community aspects, is expression of a conviction on the part of the author that topics of social science should not only be included in a general science course but should be treated in much the same way as are topics from the various fields of the natural sciences.
