Crystals

A crystal form is a set of crystal faces defined according to their relationship to the crystal axes. Crystal forms look differently according to each individual kind. A crystal can be cube shaped, diamond shaped, triangular and many more.
In class we did an activity where we combined the ingredients of salt, water, bluing, and ammonia. After combining these ingredients we covered a toilet paper roll in the liquid and let it set for two days. When we returned to class there were crystal formations cover the toilet paper roll. What a great activity to do with my kids in my future classroom!
