Purpose:  


The purpose of this science fair project is to grow beautiful crystals through chemistry.  Crystals are solids that have formed in an orderly pattern known as crystallinity.  You can create your own crystals by heating water with potash alum.  The water absorbs the potash alum which then forms crystals.  These crystals can have different shapes such as cubic, hexagonal, tetragonal and many other geometric shapes.


Note:  You will need adult supervision for this science fair project.


Hypothesis: 


Supersaturating Rochelle salt causes the atoms of the mixture to form orderly patterns know as crystals.


Variables:


  • Time
  • Amount of Rochelle saltRemember to take a picture each time before you shake the jar.  This will allow you to visually record the growth of your crystals.

Materials Needed:


  • Hot plate
  • Pot holder
  • Scale (grams)
  • Thermometer
  • Spoon
  • Tweezers
  • Small drinking glass
  • Medium size clean mayonnaise jars with tight lids
  • Distilled water
  • Potassium sodium tartrate (Rochelle Salt)
  • Pencil
  • Paper
  • Camera
