3. Graph your data using Excel and paste it below or attach it in a separate document. You will NOT get credit if you draw a graph. You must use a graphical program such as Excel.

4. In the space below. Insert a photo of your different bottles with the balloons on them at end of the experiment.

5. The independent variable in this experiment is a. intensity of light.

b. amount of CO2 produced. c. yeast concentration

d. sugar source

6. The dependent variable in this experiment is a. intensity of light.

b. amount of CO2 produced. c. yeast concentration

d. sugar source

7. Why are you able to evaluate CO2 production as a measurement of alcoholic fermentation? What does it tell you about alcoholic fermentation?

8. State the conclusion from this experiment. What experimental evidence supports your conclusion? Were your predictions correct? Explain why or why not.

9. What is the role of yeast in alcoholic fermentation?

10. What is the role of glucose in alcoholic fermentation?
