My 13-year-old is a natural science writer! Check out her paper on crystals (she'd be angry if she knew I posted it):Kelsea Despain

Science
Crystals are made out of atoms that are structured into a specific pattern. The atoms are usually packed close to one another with positions in space relative to another. Not all crystal patterns are simple. They grow easily by attaching itself to a surface of another crystal. The new crystal grows into what is called a “dislocation.” Because of this, clusters of small crystals are common, large perfect crystals are rare. Its environment determines how perfect the crystal will be. Large crystals also grow very slow but small crystals grow rapidly. The crystals state of matter is based on a distinct structural rigidity and virtual resistance to how it changes its shape or volume. Crystals start growing by a process called "nucleation". Nucleation can either start with the molecules or with the help of some matter already in the solution. Crystals grow into the shape that they were meant to be. Kind of like our DNA determines the color of our hair, the color of our eyes, how our bones will form, and how tall we are, the chemicals in a mineral determine what shape it’ll be. Most of the earth's crystals were formed millions of years ago. Crystals form when the liquid rock from inside the earth cool and harden. Most mineral crystals take thousands of years to grow but some can be formed at home with salt or sugar within weeks. Crystals aren’t always clear, but those are the kinds you will usually see in stores.
