Clairbourn's First Grade Aragonite Crystal Discovery

Published : Thursday, May 26, 2016 | 2:08 PM

First grade student Isaac C. returned from a family vacation to Death Valley with a “popcorn rock” to share with his classmates. The rock was a Dolomite sample purchased from a gift store.

The text on the package told of how crystal would form on the rock if vinegar was added to the rock and allowed to evaporate, at which time the Aragonite crystals would appear.

This is indeed what happened to the delight of the teachers and students. (Click on this link to see the transformation!)
