Mineral Formation Lab | Build Crystal Models

The Description

'Minerals grow as crystals' is an easy sentence to memorize and a much harder process to picture. Instead of starting with another diagram, this lab has students build the repeating structure themselves.

Students make crystal models using interlocking bricks or alternative materials, then connect their models to mineral formation in cooling magma or mineral-rich water. Cooling rate, available space, and the conditions of formation become questions they can investigate—not just words in a definition.

What Students Will Do

• Build a model with interlocking bricks or alternative materials

• identify repeating units

• connect model parts to mineral structure and growth

• explain model limitations.

Why This Resource Is Different

It's easy to build something that looks like a crystal without understanding what any of the pieces represent. The useful discussion starts when I ask: What is repeating here? What does each block stand for? What would change the size or shape of the growing crystal?

What's Included?

• Three student lab versions A, B, and C

• two-page enrichment activity

• teacher keys

• mineral-lab slideshow.

The Details

Grades 6–10 Earth Science; crystal formation, physical models, and conditions affecting mineral growth. Works with interlocking bricks or alternative student modeling materials.
