Science fair project Soda + sugar=fizz? Emma Gould
Statement of problem. How does more added sugar affect the soda’s carbonation?
overview I added sugar into two cups of the same soda and I watched it fizz up then loose the bubbles. I learned that the soda fizzes up a lot until the soda’s carbonation slowed. Timing was hard and I had to stand there for a long time with a timer.
Why soda? I wanted to see what would happen if I add sugar to soda. I didn’t know it would fizz up a lot then all of a sudden go flat. It was surprising to see what would happen.
variables Independent: sugar amounts. Dependent: how many bubbles com up after sugar is added. Control: the cup that hasn’t had any sugar added to it. The cups used The amount of soda in the cups The amount of sugar in the two cups. The type of sugar.
Hypothesis if one tablespoon of sugar is added to the soda, then there will be less bubbles in the soda because the sugar will make the carbonation of the soda go down.
Materials Diet 7 up (one cup of soda in each cup) Three of the same cups 1 teaspoon measuring cup 1 tablespoon measuring cup Granulated sugar Paper for labels Stove clock Tape A camera for documenting Safety goggles
Procedure 1. put on safety goggles 2. set up three of the same cups 3. label each cup a, b, and c 4. fill each cup with one cup of diet 7 up 5. pour one tablespoon into cup a 6. pour one teaspoon of sugar into cup c 7. leave cup b alone (control group) 8. look at all the cups and watch them until there are no more bubbles that come up. 9. Record the times 10. Put the data into graphs.

Data
conclusion I was right. It made the sodas carbonation slow and come to a stop. My experiment was a success.
Experiment errors Timing is the only error I can think of.
Applications and recommendations This experiment could help the future soda makers know how much sugar to put in the soda. I recommend doing this experiment with a better timer than I used.
