My Yeast Experiment!!!:)
Me and my partner hadlei asked the question "How does the liquid affect the yeast?" and our answer is the the sugar water is the only one that affected the yeast by making the balloon blow up and it measured 6 inches around and then on the least day it shrunk a little from deflation and it shrunk down to 4.75 inches and the all started at 4.5 inches. Our evidence is we checked everyday for change and vial e is the only one that blew up a little it started at 4.5 inches then blew up to 6 inches then shrank to 4.75 inches. Inaccuracies or sources of error are the balloons were not sealed so it let gasses out. Observations are there was no change for vial a,b,c and d but vial e grew on the second day and shrunk on the last day. I understood that out of all our liquids vial e only made the balloon blow up. A pertinent question would be why did only sugar water make the balloon blow up?

Did the temperature of the water make a difference?
Thanks for sharing.

we did yeast too, but we made a mistake because we forgot to get balloons :( so we just determined how how the smells changed overtime.
