ABSTRACT:
As I was looking through sources for my dry ice project, I've studied that it can be very dangerous when you touch dry ice with your bare hands. I wanted to find out how dry ice reacts when you add soap. My procedure is to get two bowls (one small and one big). Then I have to fill each bowl halfway with water, and add a squirt of liquid soap to the small bowl. Second, add the dry ice to the large bowl and get the rim wet. Last thing is to dip a cloth into the soapy water to get it wet and pass it across the entire rim to create a bubble skin and and wait for it to blow up. While doing my project I discovered that when dry ice and soap react together it creates a big bubble. But since I used two different kinds of soap instead of one the results were different when the bubble grew. With one of my soaps which was a hand soap the bubble grew to the biggest 7 inches. When working with the dish soap the bubble grew 7.5 inches the biggest. In my end results the dish soap ended out making the bubble bigger than the hand soap. So in my conclusion I found out that the dish soap made the bubble grow bigger.
PROBLEM: What is the effect of the different kinds of soap on the (dry ice)?
HYPOTHESIS: If dish washing soap is used instead of the hand soap then, dish washing soap will create a bigger bubble.
VARIABLES:
independent: the different kinds of soap
dependent: the bubble size
controlling:
MATERIALS:
1 large bowl
1 small bowl
dish washing soap
hand soap
20 inch x 2 inch absorbent cloth
warm water
dry ice
PROCEDURE:
Fill small and large bowl about a cup of warm water each
Add two squirts of soap in the small bowl and stir
Get the rim of the larger bowl wet with fingers
Add about a half a pound of dry ice to the large bowl
Dip cloth into the soapy water to get it wet and pass across the entire rim of the large bowl to create a soap bubble skin over the bowl
gas is released from the dry ice and the bubble skin will expand creating a bubble sphere
measure bubble size
repeat steps 1-7 for 5 trial set up
ANALYSIS:
While working on my project I found out that the dish soap created a bigger bubble than the hand soap. On the trials the dish soap had scored 3 centimeters higher than the hand soap in three trials. What I noticed is that in the first and second trial they both reached the same height, which was 7 cm and 5 cm high. In the last three trials the dish soap ended up making the bigger bubble.
PURPOSE:
The purpose of the project is to is to get people entertained. The reason for this is to see how Dry ice will react with two different kinds of soap or if there just wont be a difference. Kids will be able to find out if two different kinds of soap, like dish soap or hand soap will make a difference in the bubble growing process or not. So in this project there will be determining if the hand soap will make the bubble grow bigger or the dish soap. I think this will also be a good project for other kids to try out themselves so they can also see which will make a bigger bubble.
HISTORY:
Dry ice was first discovered in 1834, by French chemist Charles Thilorier. In his experiments, he noted that when opening the lid of a large cylinder containing liquid carbon dioxide, most of the liquid CO2 quickly evaporated. This left only solid dry ice in the container. This was a significant discovery because, now if you have a broken refridgerator you can use dry ice to keep your goods cool and fresh. By1925, dry ice was pretty soon selled all over the place.(add history of soap bubble) The history of soap bubbles is as old as soap. But bubbles are not just simply made of just soap and water anymore. This was invented by, bubble solution expert Jackie Lin. The secret solution contains a polymer that allows bubbles to resist evaporation. The polymer actually reacts with air to harden three to four seconds after a bubble is blown. If the bubbles are not disturbed as much, the bubbles can last as long as 10 days and can be caught with dry hands without popping its bubble.
.
PROCESS:
Dry ice works for many things like for freezing food products, carbonation of beverages, and is really handy when your refrigerator brakes down and you need something to keep everything cool inside and fresh. When dry ice cools down it does not leave any liquid residue, and turns directly from a solid to a gas also known as sublimation. For thats how it got its name, "dry ice." The sublimation point for dry is -108.3 degrees F and (-78.5 degrees C). When at this temperature, dry ice is also far colder than just regular frozen water, which alows it to stay intact much longer. For this is the reason dry ice is freezing food products for shipping.
APPLICATION:
Dry Ice can be used for many things like adding the right touch to the typical school volcano, or an easy to make cloud chamber. Dry ice is used for many things, like in scary movies, music videos, theater plays, and in Halloween for heavy fog to slowly and silently creep across the floor. Although, dry ice is probably one of the fun things for scienc, students don't usually get the chance to do it themselves in science class. Mostly because of teachers being intimidated by safety issues or not knowing where to get the dry ice from. Hopefully, when all these issues are solved, dry ice will appeal to a lot more memorable science learning experiments.
CONCLUSION:
In my conclusion my hypothesis ended up being correct. The dish soap ended up making the bigger bubble. During my process of my project the first two trials came out the same 7 cm and 5 cm. What first went wrong in my project was when I was trying to put over the bubble skin across the rim of the bowl. The soap kept going into the bowl, which made the soap bubble in with the dry ice which I didn't want. So as I finally got the hang of it, I found out that the dish soap made the bigger bubble.
