Excerpt from High School Physical Science, Vol. 1: Revised Edition, for Continuation Classes in Public Schools and Lower School Classes in Secondary Schools
The High School Physical Science, Part I, has been revised with the purpose of meeting the requirements of the new curriculum.
The method of treatment, which has met with the general approval of teachers of elementary science, has been retained. While the laboratory course is the special feature of the work, an attempt has been made to combine with it a concise and logical outline of the fundamental principles of the subject.
The scientific method and habit of enquiry acquired through laboratory practice is most valuable, but experience shows that the knowledge gained by beginners from laboratory work alone is inaccurate and fragmentary. The effort has been made to meet the situation by giving formulated statements of the more important principles, and, at the same time, by supplying abundant material for original investigation in connection with the development and application of the principles.
Care has been taken to select simple and typical experiments which can be performed by the pupils themselves with inexpensive apparatus.
While most of the experiments are qualitative, a number of simple quantitative determinations are included to lead the student to appreciate the more exact methods of scientific research, and to introduce him to the method of representing results graphically.
