By this method the pupils learn in their own homes and handle real cooking utensils on a real stove heated by the usual fire of that home. If it is a good thing—and no one doubts it—to learn Household Science in a school where everything that invention and skill can provide for the pupils is readily at hand, is it not worth while to enter the field of actual life and, with cruder implements, win a fair degree of success?

Cooking.—While some foods can be used as they occur in nature, most of them are made more acceptable by the application of heat. Heat softens the structure of vegetables and fruits, makes tender the tissues of meat, prepares starch for digestion, develops the flavour in many foods, and destroys the parasites and germs that may be present. The five food-stuffs are differently affected by heat—some require slow cooking, others require intense heat. Hence, it is necessary to study cooking, in order that each food may be properly prepared.

Meat, fish, eggs, cheese, milk, cereals, legumes, and nuts are classed as protein foods.
Those foods which serve solely as fuel for the body—providing heat and energy—are classed under two groups: the carbohydrates (sugar and starches) , which the body is able to use in relatively large quantities; and the fats, which the body cannot use in such large quantities, but which yield a large amount of heat and energy. Protein also serves as fuel, though tissue building is regarded as its special function. Sugars and starches are abundant in fruits and vegetables.
