Conclusion
My hypothesis was if the temperature increases the Vitamin C content will decrease. The results indicate that my hypothesis was wrong; temperature does not affect the content of Vitamin C left in the orange juice.
Future Considerations
If I were to conduct this project again I would measure the temperature more accurately, conduct more trials, keep the juice at a high temperatures for a longer time and use another juice with a lot of Vitamin C content.
The purpose of this experiment was to determine if raising the temperature would damage Vitamin C in the orange juice.

1. Slice two oranges in half and squeeze all of the juice out
2. Fill the graduated cylinder up with 25ml of juice and then into a cup labeled 80 degrees
3. Repeat step 3
4. Fill graduated cylinder with 5ml of juice
5. Repeat 2-5 until all 4 cups have 55ml of juice
6. Take the indophenol and pour 10 ml into graduated cylinder
7. Pour that 10 ml of indophenol into a vial and repeat for other cups
8. Fill pan with water
9. Put thermometer in cup labeled 80 degrees and then put cup in water
10. Put pan on stove or burner
Experiment
11. Turn burner or stove on and wait for thermometer to reach 80 degrees Celsius
12. Maintain 80 degrees for 10 minutes
13. Repeat 10 and 13 for cups labeled 60 and 40 degrees
14. Take the cup labeled 20 degrees and wait for it to cool to 20 degrees Celsius
15. Get the dropper and fill it with juice
16. Drop the juice into the indophenol, swirl and wait for it to turn clear
17. Repeat 16 and 17 for the other cups
18. Record data
12 oranges
4 cups
125mL of indophenol
1 eyedropper
4 vials
1 graduated cylinder
1 pan
1 metric thermometer
The results of the experiment were the various temperatures did not damage the Vitamin C. The first, second, and third trial took 13 drops for twenty degrees. The 40 degrees took 14 drops the first trial, 12 the second trail and 13 drops for the third trial. The 60 degrees
