Description of the activity/assignment

This is a short and simple exercise requiring students to examine and compare different crystal shapes. Cardboard models and wooden blocks are used as ideal representations of real crystals. Students examine the representations and determine what shape properties they have in common. They then discuss what it means if crystals of different minerals share some shape properties.
