The Amazing Fifeshire Dry Ice Experiment!!!

On Friday morning, 13/5/11, Room 7 and 8 did an experiment on Dry Ice! 




Question: What will happen when we put Dry Ice in water? Warm water? Cold water???






Purpose:
To see whether Dry Ice changes form in water. To see if the water temperature makes a difference.




To proceed the experiment we needed:
-A cup of warm water
-A cup of cold water
-A container big enough to put in both cups + extra space
-Dry Ice Cubes
-Dish washing liquid
-Red food colouring
-Long Tongs



(Kimberley's) Hypothesis:
The Ice will stay dry but steam up.



We needed the method what was it....


1. First of all we put the 2 cups of water in the container on top of a table.
2. Next Miss Rodman got the Tongs and picked up a cube of Dry Ice and put it into the Cold water.
3. She put a cube of Ice in the Warm water.
4. Miss Rodman repeated steps 2 and 3 until all the Ice was in the Warm or Cold water!
5. Next she added Red Food  Colouring to both mixtures (Cups of water).
6. After the Red food colouring had been added Miss Rodman included the Dish washing Liquid.





Observation
Kimberley saw that when the ice went into the cold water it started steaming then bubbling. When the ice went into the hot water it steamed up then started frothing, with a bit of bubbling.




Conclusion:
Kimberley's Hypothesis was correct because the ice stayed dry but steamed up at the start.
