Why Do Bakers Use Yeast to Make Bread?
The origins of bread making are lost in history. Archeological evidence indicates that humans have been baking bread for thousands of years. The Egyptians are credited with baking the first leavened breads (those containing yeast) as well as developing a formal bread-making industry. “Uncle John’s Original Bread Book” by John Rahn Braue devotes a portion of its introduction to the history of bread making. You can conduct a science experiment about yeast and bread and eat your results.
