Review:

This kit allows children to conduct chemical experiments to grow aquamarine crystals, glow-in-the-dark crystals, a quartz cluster, and a crystal snow tree. The kit includes a large bag of white crystal compound, small bag of blue seeding mixture, square transparent base with cover, hexagonal transparent base with cover, shallow hexagonal container, glow-in-the-dark moon crystal base, stirring bowl, stirring spoon, one set of crystal snow tree paper and detailed instructions.

Experiments include chemical reactions such as the results of combining citric acid, sodium bicarbonate, and water; after the initial experiment, there are several additional experiments that build on the basic concept: what happens when they use hot water versus cold water, replacing citric acid with vinegar (another acid), and how the order of the experiment affects its outcome. Other experiments focus on molecular movement; for example, do molecules move faster in cold or hot water? The final group of experiments focuses on the scientific method and synthesizing the concepts learned in the previous two series of experiments.

In general, the Crystal Science experiments worked well, although our testers were somewhat disappointed that their crystals did not form quite the shape or size of those on the box. It should be noted, however, that the size difference could be a function of time given to grow. This is a fun introductory kit to crystal growing that can open the door to further scientific exploration.
