You will have a party coming over soon and you need to make some ice
cubes for the drinks. To make the ice you fill up an ice tray with
water and place it in the freezer. In the cold temperature of the freezer, water will freeze and become ice in a few minutes or a few
hours. The time that it takes for water to freeze (or become ice)
may depend on many different factors.
For example, the temperature of the freezer, the size of
the freezer, the way that you stack materials in the freezer
and many other factors may affect the speed of freezing water. In
this project we want to see if the temperature of water used to make ice
affects the time it takes for water to freeze. Is it better if we fill
up our ice trays with cold water or warm water?
