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?
