Ward's® Geometry of Crystals Lab Activity

Clear, three-dimensional models display crystal symmetry.

Use this lab activity for solid reinforcement of any crystal structure lesson. The provided forms allow students to construct three-dimensional crystal shapes, then insert rods into each model along the axes. Once they have completed the model, students will be able to determine the angle between axes, the geometry of the facets, and the symmetry and repetition present in each crystal type. The kit includes enough materials for six setups, as well as mineral specimens to compare to the models.
