Book Description

Excerpt from Elementary Physics and Chemistry Second Stage This book is the second of three little volumes containing a course of experimental work on the elementary principles of Physics and Chemistry. A knowledge of the scientific meaning of such facts of ordinary experience as are described and examined in this and the two companion volumes ought to be possessed by everyone. Wherever the study of science is being commenced, it should be through the consideration of the properties of familiar things: for this is the best way to encourage an intelligent interest in scientific reasons and results. The course of work here followed is thus as suitable for the lower forms of secondary schools as for schools of other grades. The value of practical exercises in all scientific instruction, however elementary, is now so widely recognised that it is almost unnecessary to advise that the experiments described in each lesson should be actually performed. Unfortunately, it is not often possible to provide accommodation and apparatus sufficient to enable individual pupils to experiment. This difficulty has been borne in mind in designing the form of the following lessons, each of which is divided into two parts - the first consisting of instructions for the performance of simple experiments, the second of explanations of the principles taught by the practical work. When circumstances permit, every pupil should perform the experiments, and when this is impossible he should see them done by someone else.
