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.

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 pops
5. Once the bubbles pop then you can start
blowing more
6. 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 this
3.the smaller the bubbles the longer it
stayed floating
4.a bubble froze to the side of the fish
tank
DATA
Number 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
