25 pieces, 15 experiments

Grow dozens of dazzling crystals and conduct 15 illuminating experiments with this classic science kit by Thames & Kosmos. Experiment with 4 chemically different crystals, each with different properties, including potassium alum crystals that form regular octahedrons, rapidly-growing sodium sulfate crystals, long needle-shaped sodium acetate crystals, and plaster which is made from gypsum crystals.

Grow three chemically-different types of crystals that exhibit not only different colors, but also different shapes. Build three-dimensional geometric models of common crystals shapes including octahedrons, tetrahedrons and rhomboids. Mold your own crystal geode. This is a hollow rock with crystals growing inside!

Learn how to test and identify minerals with your very own collection of real specimens included in the kit. Conduct tests to determine a mineral’s chemical and physical properties such as color, luster, streak color, hardness, density, magnetic properties, and carbon, sulfur or iron content.

Investigate the geologic rock cycle and learn how the three main categories of rock: igneous, sedimentary, and metamorphic rocks are formed, altered, destroyed and formed again.

This kit is thoroughly tested and safe: Over one million units of this kit have sold worldwide. A full-color, 32-page experiment manual guides your experiments in crystal chemistry and Earth science.
