Observations and results:
we observed that in the warmer water bath the yeast did ferment faster because we could see more bubbles coming from the test tube then the test tube in the cooler water bath. In the class data table you can see that in the 20º water bath the class total was 9 bubbles with an average of 1.5 and in the 38º Celsius water the total was 556 and the average was 92.6 this 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.
