2 Introduction The refrigerator is used for keeping foods cool and preventing the foods from rotting or liquids from going bad. Over time it has changed from ice box to Freon. The ice box Picture from e-book A Freon refrigerator Picture from e-book

3 The Ice Box The ice box looked like a wooden closet. It had a nob and it had a wooden drawer for the freezer. It worked by a ice man bringing ice each couple of days and they put in the ice in the ice box so the ice keeps the food cool. It was created around 1900 by Thomas Moore. People s lives were changed in a positive way because they didn t have to hope for cold weather they could just put ice in their ice box and it would cool the food down. People s lives were changed in a negative way because it was really expensive and they had to put the ice in the ice box and it was really tiring to put the ice in the ice box.

4 The Mechanical Refrigerator The mechanical refrigerator looked like a gas and it made the refrigerator look a lot more efficient. It worked by the gas made the refrigerator cool down and the refrigerator wasn t flammable. It was created around 1931 by Thomas Midgley, Jr. People s lives were changed in a positive way because they didn t have to worry about it catching on fire and it was more efficient then the ice box. People s lives were changed in a negative way because Freon damaged the ozone layer.

5 My Opinion Overall, I think the change from ice box to Freon is a positive because ice was really tiring to put in the ice box and Freon was a lot more safe and more efficient than the ice box but Freon damaged the ozone layer.

23 The Ice Box The ice box looked like it had handles, was usually wood, brown, and big. It worked by people delivering ice, then you would put it in your ice box and keep food and other things cool or frozen. It was created around 1900 by Dr. William Cullen, Michael Farady, Dr. John Goorie, and Thomas Moore. People s lives were changed in a positive way because they didn t have to dig a hole, it helped keep food cooler than before. Their food didn t go bad, and it cost less money than now. People s lives were changed in a negative way because when ice melted it would spill on the floor and that could be dangerous like if someone didn t notice a spill and slipped.

24 The Mechanical Refrigerator The mechanical refrigerator looked like white or silver usually, bigger than before, handles, and usually metal. It worked by Freon, they would make it in the factory or place and put the Freon in it or someplace near it and the Freon will make it work( Freon is gas) It was created around 1931 by Thomas Midgley Jr. People s lives were changed in a positive way because they didn t have to make sure there were spills anywhere and it was better and easier with freezing or cooling something. People s lives were changed in a negative way because Freon is harmful to Earth s Ozone layer. They often cracked open. When they cracked open, they got people sick. They also cost a lot. They weren t allowed to make them any more.

25 My Opinion Overall, I think the change from the ice box to Freon is both positive and negative because the ice box is more work and you could slip but Freon is harmful to Earth s Ozone layer.
