In the home, scientific progress has made life easier and more pleasant. A housewife once had to spend almost all of her time washing and sewing clothes, cooking and preserving food, cleaning house, and tending fires. Science has provided electric energy to run washing machines, sewing machines, refrigerators, and air conditioners. Electric light had replaced the 5 candles, oil lamps. and gas flames that once lighted homes. Frozen foods and automatic stoves make the preparation of meals more convenient. Detergents have made cleaning and washing easier. These and other advances have given the housewife more time for recreation and community activities.
