Minerals Model Set

Explore the building blocks of Earth's crust through hands-on molecular modeling!

The Minerals Model Set allows students to investigate the structure of silicate minerals, the most abundant group of minerals found in Earth's crust and mantle. By constructing three-dimensional models of silica tetrahedra and the six major classes of silicate minerals, students gain a deeper understanding of mineral chemistry, crystal structures, and the relationship between atomic arrangement and physical properties.

Through guided inquiry and model building, students discover how a simple silicon-oxygen tetrahedron can be arranged into an incredible variety of mineral structures, including olivine, tourmaline, augite, tremolite, biotite, quartz, and feldspar. Students also explore crystal lattices, unit cells, and the use of X-ray diffraction in determining mineral structures.

What Students Learn

• Composition and structure of silicate minerals
• The silica tetrahedron as the fundamental building block of minerals
• The six major classes of silicate minerals:
  • Nesosilicates (Island Silicates)
  • Sorosilicates (Double-Island Silicates)
  • Cyclosilicates (Ring Silicates)
  • Inosilicates (Chain Silicates)
  • Phyllosilicates (Sheet Silicates)
  • Tectosilicates (Framework Silicates)
• Relationships between atomic structure and mineral properties
• Crystal lattices and unit cells
• X-ray diffraction and crystal structure determination
• Why silicate minerals dominate Earth's crust

Included Activity

The set includes a comprehensive modeling activity designed for approximately two 50-minute class periods. Students:
