Views:209551|Rating:4.57|View Time:4:18Minutes|Likes:1587|Dislikes:148
Welcome to science at home in this experiment we are exploring the fermentation between yeast and sugar. Yeast uses sugar as energy and releases carbon dioxide and ethanol as waste. Yeast and fermentation have been used for thousands of years when making bread. At the end of this episode you will be able to demonstrate fermentation, explain why yeast and fermentation make a balloon grow and explain the chemical reaction that occurs during fermentation.
