A Crystal Lab
Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures.
Normal Community High School
Crystalline Structure
Cubic crystals can have 6, 8, and even 12 sides. Here is a presentation that shows pupils three different kinds of cubic crystalline structures: cubic, body-centered, and face-centered. These structures are then applied to three...
