Abstract:(Kim)
We studied dry ice and how it sublimates (why?). Sublimation is when a solid slowly turns into a gas, sublimation occurs faster in water (run on). Our first step was to put 1 chunk of dry ice into the bowl. After, we soaked the strip of cloth into soap, ran it around the bowl and saw the bubble slowly form. When we put the water in the dry ice there was a lot of fog. After we ran the soap around the bowl, we began to see less fog than before. Seconds after, the bubble grew bigger and bigger, when it popped, there was fog everywhere. (What are you comparing?) While conducting our experiment we leaned that dry ice quickly reacts with soap.
Problem:(sophia) (variables are backwards!)
Does the amount of dry ice depend on the size of the bubble?
Hypothesis:(sophia)
If you put a small chunk of dry ice and dish soap/ bubble solution in the water,
then the bubble will get big and pop (compared to...).
Variables:(sophia)
Independent- the soap
dependent-the bubbles height
control- cold water dry ice from same place
Dry ice and water
fog
Bubble
Materials:(Kim)
1 cup of water
A bowl with a lip around the bowl
A long strip of cloth
1/2 cup of soap(Dawn) mixed with 1/2 cup of water
2 lb of dry ice
Safety goggles
Gloves
Thermometer
Procedure: (Kim)
Put 2 lb of dry ice into the bowl
Add 1 cup of water
Soak string of cloth into soap
Run cloth around the bowl
Watch as the bubble forms
Take a string and carefully and slowly wrap it around the bowl
Repeat this 5 times, each time adding 1 lb more
Data table:
Graph:(Kim)
Analysis:The results were that trial 2 had the highest height with the handsoap and trial 3 was the lowest height.
Conclusion:Overall the project was great we figured out that the more dry ice and soap we added created a bigger bubble.Our hypothesis was proven correct because the bubble came out big and covered the entire bowl.
Purpose: (use 3rd person; why should people care about your project?)(Sophia)
This project was chosen to see what caused the bubble to grow. The instructions for the experiment are very easy to follow and inexpensive. The purpose of the experiment is to see how the dry ice bubble will react to the soap. The purpose was to have a blast and watch the bubble explode in front of our eyes. The whole point was to see what would happen to the bubble if it popped when it did, smoke came out.
History: (Kim) (period goes after parenthesis; this seem copy & pasted. Add some of your own words to make this longer)
Dry ice was discovered by Charles Thilorier, a French chemist in 1835 when he opened a metal cylinder with liquid carbon dioxide inside (Ken,2013). For 60 years, dry ice was studied, however it was not used. Use for dry ice began in 1925 and was used for fire extinguishers in the United States. Dry ice was also used for tire pumps and making soda water at home. But in the end, only the fire extinguisher became very useful. (Smith,2013).
Soap goes way back in time from 2800 B.C. Soap was invented by the Babylonians, it was made from fats boiled with ashes. Soap was used for cleaning wool and cotton
Process: (bold glossary terms; examples below)(Angeline)
this seem copy & pasted. Add some of your own words to make this longer; what's the source?) Explain about how dry ice sublimates in the first paragraph. You can include detailed information about the movement of particles (see your textbook for more information) In the 2nd paragraph, you can talk about how dry ice reacts with soap. (Angeline)
As the solified carbon dioxide, a bleak object, sublimatescarbon dioxide vapor is caught inside the soap, the tempature drops to a cryogenic level. Then, the bubble expands but the soap does not evaporate quickly which makes the bubble stay for a long time. When the soap evaporates, the bubble pops. (This is the procedure, not process-->) Water was put inside the bowl then the dry ice was added,we used soap to put around the lip of the bowl with a long string of cloth.We (use 3rd person only) watched the dry ice expand into a bubble it took about a minute to form.We tried the experiment five times.The first time it didn't work so we added more dry ice and water to the bowl.
The soap traps the dry ice so it can form in place, and create a huge bubble.When the bubble pops visible smoke flows out of the bubble and into the air.Soon after soap was put around the bowl and a new bubble was formed.Seconds after the bubble popped more soap was added to the bowl.Bubbles repeatedly formed until all the dry ice sublimated.
Application: (Kim) There are many uses for dry ice. For example, if there's an emergency or any natural disaster that causes the power to go out, dry ice can be used to replace a refrigerator and it wont make a mess because the dry ice would sublimate and turn into a gas. Dry ice can be used for freezing perishable foods when being shipped, to prevent bacteria, and to preserve medicine that needs to be kept at a certain temperature.(Ken,2013) Dry ice is sometimes used as part of theater productions and performances to create fog. It is also used to freeze lab samples and to make ice cream. Hopefully in the future, scientists will find more ways for dry ice to be used on a daily basis.(Smith,2013)

Reflection:
Throughout our project we learned about Dry ice and the effect of what it does.What we were testing was the different sizes of the dry ice and how it would affect the bubble. Will it make it bigger or smaller because of the amount of the dry ice I learned that the dry ice affected the size of the bubble. It was suprising because when the bubble would pop, little bubbles would form afterwards. When the bubble popped it formed a bigger bubble so we didn't have to put that much dry ice. Our prediction about the project was true it did form the bigger bubble that we expected.
I learned that dry ice is a short process,but fun when watching the bubble form and pop with smoke. I wonder if we put a whole bottle of soap would the bubble get bigger or stay the same? The only thing that went wrong with the bubble is that it wasn't a full bubble, it was half a bubble a couple of times that we tried, but then it would pop and form a new bubble. What would do for the next experiment is put more soap to see if it affects the bubble. (What are you trying to test- independent variable)
