FOOTNOTES:
[1] Teacher’s Note.—The term “foodstuff” is used in place of “food principle,” as being the later and better term.
[2] This is the “greater calorie” or “kilogram calorie,” and is written Calorie to distinguish it from the “lesser calorie” or “gram calorie,” largely used in physics and chemistry.
[3] Teacher’s Note.—The machines operating with a crank are examples of the “wheel and axle,” or the windlass, or both. The mechanical advantage can be worked out mathematically,—a good problem for the physics or mathematics class. See “Household Physics,” C. J. Lynde.
[4] Teacher’s Note.—A good way to study utensils is to begin with the school kitchen equipment. Utensils for the home kitchen can be listed in the notebook, as these are used in the school kitchen, having the list grow by degrees throughout the year. For reference, have a price list and illustrated catalogue from some good firm.
[5] Laboratory management.—In the school kitchen the dish-washing may be done at the sink by housekeepers appointed for the day, or if equipment allows, the work may be done in twos with some definite plan for dividing the work.
[6] These terms perpetuate the names of scientists famous for their work in electricity. Volta was an Italian who invented an electric battery; Ampere was a French electrician; and Watt a Scottish engineer and electrician.
[7] Teacher’s Note.—The teacher of physics can coöperate here, and indeed throughout the whole topic of apparatus and cooking processes.
[8] Teacher’s Note.—If a meter can be used, very exact problems can be worked out with gas and electricity.
