Caves, Crystals & Mineral Treasures

$23.95

Product Description

We start our inquiry by plopping a piece of plain, black, dolomite into a tart pan and covering it with vinegar. Within an hour tiny white, aragonite crystals start to form on the surface and over the course of 5-6 days it appears that the rocks are covered with popcorn. To understand the chemistry behind the first experiment, we then test calcite and limestone for chemical reactions. By looking at granite, you will understand that rocks are composed of two or more minerals. Mineral identification using 5 large, beautiful samples is presented next. And finally, you will make your own toothpaste using two minerals, a little water and some elbow grease. 6 activities in each kit.
