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
