Book Description

Excerpt from Exercises in Chemistry The exercises contained in this book are systematically arranged to accompany McPherson and Henderson's An Elementary Study of Chemistry. The authors believe that the course in chemistry for secondary schools should consist of three recitations and two laboratory periods weekly for one year, and that the laboratory periods should consist of two consecutive recitation hours of at least forty-five minutes each. In accordance with this view an effort has been made to have the exercises of such length that each can be completed in one and bf one-half hours. It is no longer necessary to emphasize the importance of laboratory work as a part of the course in elementary chemistry, since it is universally admitted that some laboratory experience is essential for a thorough comprehension of the subject. It is none the less true, however, that laboratory work is of very doubtful value unless carefully directed by an experienced teacher toward some definite end. It is in the hope of aiding such a teacher that this little exercise book has been prepared. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
