THIS book presents a logically arranged and teachable first-year 

 high-school course in general science, dealing with concrete scientific 

 facts of everyday interest and worth-while significance. The material 

 is drawn from the home, school, and community environment, and 

 all the sciences contribute to the survey, each being used as needed. 

 Unity is secured through the logical and progressive arrangement of 

 the topics which make up the course. 



These fall under five main heads: I. The Air, II. Water and 

 its Uses, III. Work and Energy, IV. The Earth's Crust, V. Life 

 upon the Earth. Each topic is connected with that which follows, 

 the last in one main division leading naturally to the first in the next 

 division. The material has been chosen for its value in developing a 

 scientific method of thinking, and in giving the young pupil a much- 

 needed basis for later science work in high school. Laboratory work 

 is intended to accompany the text, which suggests many simple but 

 valuable experiments. 



The book is the outcome of six years' experiment with general 

 science in the University High School, The University of Chicago. 

 For the past four years the course has been given essentially as now 

 published. Its plan and materials have in addition been submitted to 

 many high-school teachers, and a variety of helpful suggestions thus 

 secured. In short, the book has been made in the laboratory and the 

 classroom and is admirably adapted to meet actual class needs.
