Crystallization Lab


Procedure
1.Put a milk into a zip lock.
2.Place it in the basket but put it at the edge.
3.Put ice into a basket.
4.Use something to squeeze it.
5.Squeeze until it froze slightly and then put a topping in it.
6.Squeeze it until it froze and then eat it.

Questions
1)  why do we add salt to the ice?
To make the temperature of ice drop.
2)   why do we add the cookies and other things, only after the milk has frozen slightly
If we add topping when it is not frozen ice cream will freeze slower and when we add when it froze it will not mix.
3)  what are two factors that affect the freezing you think?
Temperature and when we use something to squeeze it. 
4)  why do you need a bit of air in the bag?
To make the ice cream froze faster.
