STAGES OF CRYSTALLIZATION
There are three major stages in which crystallization happens.
1. Saturation of the Solution - solution is saturated when no more chemical
2. Nucleation - during this stage in the initial formation of crystals begins.
3. Crystal Growth - the stage in which crystals begin to form as you grow
your crystal hedgehog, you will observe each of these stages. Record your
observations as the crystallization occurs. Observations can include the
length of time it takes for your solution to become saturated, the rate at
which the crystallization occurs and notes about on which day the most
crystal growth occurred.
