Fermentation.
Purpose: To investigate the effect of temperature on the fermentation of glucose by bakers yeast. hypothesis If to separate tubes of 20% glucose solution with 1 mil of yeast is added to battery jars filled with 20 and 38 c water then the warmer one will cause the yeast to ferment at a quicker rate. Materials: -2 test tubes (100 mm. Long x 11 mm. I.D.) -2 ones-hole stoppers (size 00 w/3 mm. Hole) -Glucose -Bakers yeast suspension -Balance -Molding clay …showed first 75 words of 577 total…

…showed last 75 words of 577 total…shows a big increase in the amount of bubbles Analysis and conclusion: The data shows that the group's hypothesis was in fact correct and the yeast fermented faster in the warmer water bath. Some possible mistakes in this lab would be incorrect water temperature or an incorrect amount of glucose solution. Another mistake could be that we added too much or too little amounts of yeast or that some of the yeast was not active.
