I have attached the in class activities that I walk through with my students. Since there is no lab directly associated with my class, all of our visualization activities are done in a standard lecture room during one or more 50-minute class periods. I believe that it’s important to guide students as they explore 3D extended structures. Students should complete this activity in groups during class time. The attached file is the activity that I work on with my students. I like using visualization tools that students can use individually so they can look at solids in a way that make sense to them. I like having students use multiple representations, so we work with ICE Solid State Model Kits and DAE files (3D visualization that can be done on a smartphone or tablet device). There are many excellent activities to help students develop these skills and I’ve customized an activity for my own class. Although they have built some visualization skills by working with molecules and symmetry, they do not have robust 3D visualization abilities and have trouble using the language of solid state chemistry (unit cells, packing, filling holes, coordination number, etc…) in the context of structure. With the exception of students who have taken a course in materials science, Inorganic Chemistry I is the first time our students have encountered solid state structure. We do not cover extended solids (solid state materials) in our general chemistry program. Science Skills, Practices, and Resources.
