Create crystal shapes that help identify minerals

Model crystal shapes of various common minerals - including galena, quartz, sulfur and others - using transparent plastic. Your students will analyze the resulting "crystals" to study their structure and such properties as angles, geometry of facets, symmetry and much more! Then they'll use the included set of specimens to study the mineral's actual microstructure under a microscope, comparing it with their model. They'll even learn how crystals grow by forming several microcrystals of their own!
