![Procedure
1. Prepare Room Temperature Water: Use a thermometer to determine room temperature. Add hot
water to cold water until it reaches desired temperature.
2. Label each of the five bottles accordingly:
o Control
o 15 mL sugar
o 5 mL sugar
o 5 mL sugar substitute
o 10 mL sugar
3. Add 150 mL of room temperature water to each of the five bottles.
4. To bottle labelled 'Control' add 1 package active dry yeast. Gently swirl the solution.
5. Place a balloon over the opening of the bottle to minimize the loss of any gas from the system.
6. Use the measuring tape to measure gas accumulation in the balloon after 1 minute. Record
measurement and qualitative observations.
7. Continue to measure and record gas accumulation in the balloon at one-minute intervals for a
total of 10 minutes. Include qualitative observations.
8. To the bottle labelled '5 mL sugar' add 1 package of active dry yeast. Gently swirl the solution.
9. Add 5 mL of sugar to the solution and quickly place a balloon over the opening of the bottle to
minimize the loss of any gas from the system.
10. Use the measuring tape to measure gas accumulation in the balloon after 1 minute. Record
measurement and qualitative observations.
11. Continue to measure and record gas accumulation in the balloon at one minute intervals for a
total of 10 minutes. Include qualitative observations.
12. Repeat steps 8-11 for each of the remaining bottles. Adjust the sugar and sugar substitute
concentrations accordingly.
Communicating Your Results
1. Once you have completed your test(s), communicate your results in a lab report.
2. Your lab report should include the following sections: testable question, hypothesis, materials,
procedure (including your identified variables), observations, results, discussion, and conclusion.
3. Display your results using tables and graphs.
4. Your discussion section should include the following:
a. the basic science used in the lab
b. a summary of your results, referring to table/graph and highlighting trends in data
c. scientific concepts to explain results
d. possible further tests](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc46def1d-7af4-439c-8152-94ccbbef7e87%2Fff3fe774-1aba-45f8-b30a-9795c1db728e%2Fa53ptlg_processed.jpeg&w=3840&q=75)
