"Science Related to Life" textbooks are written to supply the need of elementary science teachers for textbooks that can be used independently by pupils. Throughout the series the author has kept in mind the aims of elementary science, as recognized by modern courses of study, namely: (1) to develop in pupils an interest in the natural phenomena about them, and knowledge and appreciation of the practical applications of science; (2) to give pupils training in the scientific method; (3) to lead pupils to appreciate the order and beauty which pervade the realm of nature; and (4) to show that science is a potent factor in human betterment, since it affords mankind leisure in which to enjoy greater comforts and cultural advantages, by giving him more comforts and greater leisure for their enjoyment, and for cultural development. Each book is divided into problems, or "units." Each problem ends with a simple summary, a set of questions, and suggestions for additional demonstrations and projects. At the end of each book are simple, interesting biographical sketches of scientists mentioned in the text. A list of reference books and suggestions for additional reading is appended.
