Thames & Kosmos Crystal Growing Kit

Your little scientist can conduct 15 fun experiments with the Thames & Kosmos Crystal Growing Kit to learn more about crystals and solutions. Your child will be fascinated by the four chemically different crystals, including potassium alum crystals, sodium sulfate crystals, sodium acetate crystals and gypsum crystals that appear in plaster. Use the plaster to create cool shapes, then grow layers of crystals on top for an exciting look to entice your little one. Help your child use dyes to color the crystals, experiment with growing crystals quickly and slowly and mold his or her very own geode. Your budding chemist can also learn about the energy required for crystallization and how to crystallize solids out of and dissolve solids back into a solution. The full-color manual guides him or her through each of the experiments for plenty of scientific investigations.

Product Highlights

  • Create fun shapes out of plaster, such as dolphins, lightning bolts and stars, and then grow crystals on them
  • Experiment with growing crystals quickly and slowly, then learn how to create one large or many small crystals
  • Display the crystals in the clear treasure chest with a locking lid once you are done experimenting
  • Crystallize solids out of and dissolve crystals into solutions
  • Note how temperatures in the solution are affected by those processes
  • Help your child understand the energy required to crystallize solids through the experiments
  • Teaches about the different structures and geometries of crystals, including octahedron-shaped potassium alum crystals and long, needle-shaped sodium acetate crystals
  • Build a geode - a hollow rock with crystals forming inside
  • Use dyes to color the crystals, and mix them to create customized colors
  • 15 experiments
  • Full-color, 32-page manual to guide your little one through the experiments and teach important concepts in chemistry and earth science

What's Included

  • Thames & Kosmos Crystal Growing Kit
  • Owner's manual
Make something new
Your child can create fun shapes out of plaster, such as dolphins, lightning bolts and stars, and then grow crystals on them. Young scientists can experiment with growing crystals quickly or slowly, then learn how to create one large or many small crystals. Findings can be displayed in the clear treasure chest.
Hands-on learning
When crystallizing and dissolving crystals into and out of solutions, your child can note the difference in temperatures in the solution to understand the energy required to crystallize solids.
Homegrown geode
Teach your little scientist about the different structures and geometries of crystals, including octahedron-shaped potassium alum crystals and long, needle-shaped sodium acetate crystals. Build a hollow rock with crystals forming inside for an exciting experiment.

Product Description

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 octahedron's, rapidly growing sodium sulfate crystals, long needle-shaped sodium acetate crystals and plaster which is made from gypsum crystals. Mold fun plaster shapes, including stars, lightning bolts, dolphins and pyramids, and grow layers of crystals on them. Use dyes to form colored crystals, and mix the dyes to grow a rainbow of custom colored crystals. Display your crystal creations in a clear treasure chest with a locking lid. Mold your own geode--a hollow rock with crystals growing inside and create a beautiful crystal cavern. Experiment with growing crystals rapidly and slowly, and observe how that affects the crystal structures. See if you can grow one giant crystal, and many small crystals on the surface of a rock. Measure how the crystallization of solids out of a solution, and the dissolution of crystals back into solution, affect the temperature of the solution. Learn about the energy of crystallization. Investigate solutions, crystallization, and the chemistry of crystal growing. Learn about the structures and geometries of different crystal shapes. This Kit is thoroughly tested and safe: Over one million units of this kit have sold worldwide.

My son loves this product. He is 8 years old and decided to buy it with his own birthday money. This is our 3rd kit and makes a great addition to his "mad scientist lab" with a long term successful result of watching science with the crystals.

My 4 year old granddaughter picked out this science kit for us to do together. After the first project, which failed miserably, I decided this is too advanced for young kids. Maybe a pre-teen would do better than this grandmother. The instructions are not clear and the instructions are in the front of the book, not on each experiment's instruction page. Our instructions said "cook", not how long or to what temperature. I learned later that more detailed instructions are in the front of the book. Not user friendly if you ask me.

Comments about Thames & Kosmos Crystal Growing Science Kit:

Got this for my 9-year old. Read the directions and it's extremely complicated. There were tons of extra things you needed to do the experiments with (distilled water, an old sauce pan, food theromwter, protective gloves, etc.....) Age range should be 13+

I bought this as a gift for Christmas. My 8 yr old daughter went crazy whe she opened it. I love the idea that it's just as much a toy to her as a learning experience!
