Learning Goals

After successfully completing this exercise, students will be able to

  • Use a gesture to illustrate the structure of a silica tetrahedron.
  • Use gestures to show how silica tetrahedra share oxygen ions in chain silicates.

Context for Use

This exercise is designed for use when students are beginning to learn about the classes of silicate mineral structures.

Description and Teaching Materials

Students use gestures to show the structures of island silicates, dislocates, single and double chain silicate minerals.
