Until about 100 years ago, there weren’t any electric refrigerators or stoves. Early humans used fire to cook food. The first stoves were heated with coal or wood fires. This is an old fashioned ice box. Ice was placed into the ‘box’ to keep food cool. If the weather was too warm, the ice would melt and the food went rotten. (C) HALFORD HOUSE / L.D.FREDERICKS 2013 4 PowerPoint Presentation: People grew their own fruits and vegetables and farmed animals such as cows, pigs and sheep .
