With Crystal Wonder, kids can grow their own crystals to gain a real understanding of a central geological process, fortunately in a few millennia less than the real thing takes. The set includes different salts in a variety of colors and the ideas and materials for using the crystals to make decorative items. Essentially, kids create a solution using some of the various salts, heat them up on top of the stove, pour it out, and let the crystals form as the water in the solution evaporates.
For the real scientists out there, you'll know that what you're doing is dissolving teeny crystals and allowing them to reform as larger ones. But the point of the learning is that kids will understand how the different molecular makeups of the different salts form different-shaped crystals.
The instruction booklet includes many different activities, including making large sugar crystals (which we always called rock candy) or salt crystals from regular table salt.
