Dependent- Amount of carbon dioxide produced as measured by distance between two points in a expanding ballon.
Control- Amount of yeast and sugar used in the experiment.
What happens when the temperature increases?
More CO2 is produced, as shown by the expanding balloon, which indicates that the rate of alcohol fermentation is faster.
Why do we put two dots on the ballon?
So we can measure how much the ballon has expanded in the experiment and therefore measure the increase of CO2 production.
Why do we put sugar?
To feed the yeast, it needs to be fed, there needs to be glucose for yeast so that fermentation can start.
Why the ballon?
As it expands, it shows how much CO2 is produced, which tells us about the rate of fermentation we want to know about.
Why?
Heat activates the enzymes in the yeast and results in the yeast molecules working to have a faster cycle and increase production capacity to produce CO2 and consume sugar, with faster production, fermentation happens faster.
