Introduction to Mineral Crystals

Kit #400

The purpose of this Lab-Aids® kit is to introduce the Crystal Systems found in minerals. Because this can be a difficult concept, four of the most common systems are singled out for study. Students will be able to construct these forms, study the geometric forms of the faces of these four crystal systems and correlate these forms to identify systems in some common minerals. Almost all minerals are crystalline in structure because their atoms are arranged in an orderly pattern. Even the smallest fragment will show this pattern with the use of x-rays. Generally, minerals fall into one of six crystal systems. Many of these systems have other polyhedral forms. An example may be the cubic or isometric system with forms such as cubic, octahedral and dodecahedral.
