OLogy: Grow Rock Candy

Create your own crystals with sugar. Then enjoy your tasty treat!

Whether it’s big or small, rough or smooth, almost every rock is made of minerals. Each mineral has a unique crystal pattern and compostion.
Think about the mineral salt. It is made of cube- shaped crystals. No matter where you find it � on your table or at the beach � its crystals will be shaped like cubes. Look at the pictures of the crystals that make up diamonds, quartz, muscovite, and topaz.

How would you describe their crystal shape?
