ACTIVITY 14: MAKING CRYSTALS<br />
m6: <strong>Microscopes</strong> <strong>and</strong> <strong>Crystals</strong><br />

Making <strong>Crystals</strong><br />
CTIVITY<br />
What is a crystal? <strong>Crystals</strong> are solids that form in special ways. There is a regular<br />
repeated pattern that occurs each <strong>and</strong> every time new crystals form. Because of<br />
this arrangement, crystals can take on strange <strong>and</strong> interesting shapes naturally.<br />
When we grow crystals, the atoms <strong>and</strong> molecules are separated, <strong>and</strong> as the water<br />
evaporates, they fall naturally into their place in the repeated pattern. In this<br />
activity you will be learning how to make crystals.<br />
