What changes the amount of dry ice bubbles
Rand Johnson |Carleen McNees | Syracuse Jr. High
STATEMENT OF THE PROBLEM
• What changes the amount of dry ice bubbles?
2
RESEARCH
• Summarize your research here in three to five significant facts:
– Dry ice is frozen carbon dioxide.
– Dry ice has a surface temperature of -109.3 degrees Fahrenheit (-78.5degrees C).
– It should never be touched with bare hands
– CO2 Can be dangerous in enclosed spaces
– If you breath in too much carbon dioxide gas, you can suffocate because the lungs cannot get enough oxygen.

HYPOTHESIS
• If dry ice is carbon dioxide in a solid form CO2 and it is mixed in with
different types of liquids (apple juice, Pepsi, Coke, punch etc.) then
those different liquids and environments (metal mixing bowl, platic
mixing bowl, and different sizes of drinking glasses may effect the
amount of bubbles being produced.

PROCEDURE: MATERIALS
• Dry ice 9 lbs
• 2 pair of metal tongs
• 1 16 ounce Utah Jazz drinking glass
• 2 clear 12 ounce drinking glasses
• 2 cups of water
• 1 clear vase
• 1 large plastic mixing bowl
• Dawn dish washing soap
5
PROCEDURE: MATERIALS
• Wash Cloth
• 1 large metal bowl
• 1 cup of Apple Juice
• 1 cup Pepsi (wild cherry)
• 1 cup Coke Zero
• 1 cup Tampico orange punch
• 2 large empty Cottage Cheese containers for the dry ice
• 2 paper plates
• Normal Ice
6
PROCEDURE: STEPS
• List all of the steps used in completing your experiment. We did five
different experiments: 1. Making a dry ice bubble, 2. Apple juice in a
clear glass , 3. Pepsi in a glass, 4. Coke Zero in a glass, 5. Tampico
orange drink in a vase, 6. Comparing dry ice and ice from the freezer.
• 1. Making a dry ice bubble in a mixing bowl.
– Add 1 cup of dry ice.
– Two cups of water.
– Liquid soap on a wash cloth.
– Liquid soap around the rim of the metal bowl.
– Run the soapy wash cloth around the metal bowl.

PROCEDURE: STEPS
• 2. Apple juice in a clear glass.
– Pour 1cup of apple juice into a clear glass.
– Add a small piece of dry ice to the apple juice in the glass.
– Wait until the dry ice or CO 2 dissolves before drinking.
8
PROCEDURE: STEPS
• 3. Pepsi in a clear glass.
– Pour 1cup of Pepsi into a clear glass.
– Add a few small pieces of dry ice to the Pepsi in the glass.
– Wait until the dry ice or CO 2 dissolves before drinking.
9
PROCEDURE: STEPS
• 4. Coke Zero in a clear glass.
– Pour 1cup of Coke Zero into a clear glass.
– Add a few small pieces of dry ice to the Coke Zero in the glass.
– Wait until the dry ice or CO 2 dissolves before drinking.
10
PROCEDURE: STEPS
• 5. Tampico orange drink in a vase.
– Pour 1cup of Tampico orange drink into a clear vase.
– Add 1 cup of dry ice to the Tampico in the vase.
– Wait until the dry ice or CO 2 dissolves before drinking.

VARIABLES
• Constants: The amount of dry ice for the experiments with apple juice,
Pepsi, an Coke Zero.
• Controlled variables: Sizes of the clear drinking glasses 12 ounces.
• Independent (manipulated) variable: The one variable that you
purposely change and test was the size of the container or glass.
There was a metal mixing bowl and a plastic mixing bowl.
• Dependent (measured) variable: The experiment I was trying to test
was what changes the amount of dry ice bubbles, what was effected
during the experiment was the amount of bubbles it created.

DATA/OBSERVATIONS
• In the first experiment when making a dry ice bubble in a mixing bowl
we observed that if there was too much water it was harder to make a
large bubble and would have a lot of small bubbles.
• In the second experiment when the dry ice was added to the clear
Utah Jazz glass that it began to bubble and almost over ran the glass.
Once the bubbles were gone then we were able to drink the apple
juice.
• In the third experiment we added roughly the same amount of dry ice
to the Pepsi. After awhile we noticed when the bubbles stopped we
were left with a big piece of what appears to be a chunck of Pepsi ice.
13
DATA/OBSERVATIONS
• In the fourth experiment we did the same thing as with the Pepsi but added Coke
Zero. This was a 12 ounce glass so it was smaller and when the dry ice was added
it bubbled about the same as the Pepsi.
• In the fifth experiment we used Tampico orange drink and a large plastic bowl. We
added two cups of dry ice and it really effected how many bubbles were there
when compared to the smaller drinks with just a few small pieces of dry ice. We
were able to get larger chunks of orange ice. We then put it under some warm
water from the faucet and noticed that in the middle there was still a small
amount of dry ice.
• In the sixth experiment we had two plates; one with dry ice and one with regular
water ice. We left them both out for about an hour and noticed that the plate with
the water ice melted while the dry ice was still on the plate.

CONCLUSION
discovered that dry ice bubbles in this experiment would not have been
created when I did this experiment
• 1) Dry ice bubbles were created in this experiment
•2) The data did not support the hypothesis, why it didn’t is because my
hypothesis was incorrect
