BUBBLES and DRY ICE
BIG QUESTION
• What will happen to a bubbles if it floats over dry ice?
If there is a bubbles floating over dry ice then I think that it will pop.I think the bubble will pop because over a dry surface the wet bubble becomes dry and pops
That the bubbles can last for a while in the fish tank
You can make the bubbles glow.
Who would guess that you could have this much fun with bubbles and dry ice?
You can change the color by food coloring.
It can be so much fun to watch.
– MATERIALS• Bubbles from the store• Dry ice 7 inches by 5 inches• Video camera• A fish tank• Pen and notebook• Assistants• Gloves/Tongs• Warm Water
– MUST BE CAREFUL WITH THE DRY ICE
1. Put 1/2 inch of warm water in fish tank, then put in the dry ice
2. Now make sure that the person video taping is ready to start taping
3. Blow the bubbles and start taping 4. Keep the video camera running until the
bubble pops5. Once the bubbles pop then you can start
blowing more6. Right down in your notebook any observations
you had about this experiment.
– CONTROLS• The bubble and the
dry ice
– VARIABLES• The bubbles and dry
ice
OBSERVATIONS
1.it was hard to blow the bubbles into the fish tank
2.we had a lot of fun doing this3.the smaller the bubbles the longer it
stayed floating4.a bubble froze to the side of the fish
tank
DATANumber of times
What happened What happened What happened What happened
#1 The bubbles would hit the fog and pop
the bubbles would hit the side and pop
sometimes the bubbles would hit each other and pop
It was hard to get the bubbles in
#2 The bubbles would bob up in down
A bubble got frozen on the side
The bubble just kinda sat still
It was hard to get the bubbles in
#3 The smaller the bubbles were they floated better
We had to stand still so the air in the fish tank would not move
When we moved the bubble would hit a side and pop
It was hard to get the bubbles in
#4 Once the bubbles floated for awhile it would sink lower
Some of the bubbles we had to blow into the fish tank
The dry ice and warm water mad it sizzle and pop
It was hard to get the bubbles in
ANAYLSIS OF DATA
• Yes, my experiment did test my hypothesis
• I know that my experiment tested my hypothesis because the bubbles did pop
CONCLUSION
• Yes my hypothesis was correct• What I would change in my experiment
would be using regular ice instead• Some new questions I had were, why
did the warm water and dry ice make fog. Why did some of the bubbles float in the fog and some did not
