Excerpt from Foods and Sanitation: A Text-Book and Laboratory Manual for High Schools
This book is the result of many requests for the laboratory manuals used by the writers in their high school work. The experiments have been used in a progressive high school where no special preparation has been required of the pupils before undertaking the work. The text has been drawn from sources too technical or scattered for high school pupils and modified for them.
I. The Aim. It is planned, by experiments and many applications, to give an understanding of the scientific principles underlying:
1. The economical use of fuel.
2. The processes of sterilization and food preparation.
3. The choosing of food in regard to its composition and condition.
4. The selection of food for the normal body.
5. Important conditions of home sanitation.
II. The Method. It is hoped the method is such that the pupil will get principles rather than isolated facts; that she may be able, with these principles, to make independently many more applications than are given in the book. It is hoped, above all things, to stimulate thought rather than imitation. Instead of one recipe, various proportions and conditions have been given to gain a greater comprehension of the effect of different ingredients and conditions, and so to achieve greater mastery. With a little experience the pupil can make adjustments to material, economy, and particular desire.
