Grow dozens of dazzling crystals and conduct 15 illuminating experiments with this classic science kit. Experiment with four 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.
Make Your Own Home Grown Crystals
I figured that it would be an interesting activity for all of us to get into. We would take turns examining each one in detail. As soon as I picked up my daughter from school, I discovered that she had opened the box while waiting for me, and lost 3 of the rocks on her way to the car. In addition, she had shaken up the contents — meaning, all the rocks were not in their proper receptacles when I got to them! I might have made an empty threat to never buy anything from the book orders ever again.
In stock: Usually ships within hours. Your order will ship on or around the release date. Grow three chemically different types of crystals that exhibit not only different colors, but also different crystal shapes. Build three-dimensional geometric models of common crystals shapes including octahedrons, tetrahedrons, and rhomboids. Mold your own crystal geode - a hollow rock with crystals growing inside! Learn how to test and identify minerals with your very own collection of real specimen 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.
Children and parents delight in growing their own colored crystals with the Smithsonian Crystal Growing Kit. The kit also provides a great opportunity for children to learn about rock and mineral formation, while growing their own crystals and geodes. The kit includes safety equipment, crystal growing chemicals, dye, stones, a tray for growing and a magnifying glass for observing the crystal formation. Children should not grow crystals without adult supervision, as the chemicals used can cause injury. Put on your enclosed safety goggles to protect your eyes from chemical fumes. Ready your lab area by covering all the surrounding surfaces with a layer of newspaper.
