Lab-Aids: Geometry of Crystal Structure Kit

With this interesting and fun kit, students use transparent pre-cut shapes to construct models of the six basic crystal shapes. They insert axes at established center points on each crystal face. Using the goniometers, which are provided, students measure the length of the axes and the angles formed. They observe the geometric shape of all facets (squares, rectangles, and triangles) and record the data about each crystal form. By rotating the model on a central axis, students study the symmetry and repetition of forms.‚ 

They derive their own definitions of each crystal form using the measurements and observations recorded in their data charts. This is also an excellent math-science activity! This activity expands on the four basic crystal systems introduced in Introduction to Mineral Crystals LAB-400.
