Looking for a hands-on science project for your homeschool? Need a hands-on experiment to add to your science topic on solutions, mixtures, phases of matter, or crystals? If so, this kit has it all. Here is my review of Thames and Kosmos’ Crystal Growing Kit, a review of what we learned, and photos of us growing crystals.

Before Starting This Kit
Before starting this kit, you may have to make a couple of small purchases. I had to purchase some distilled water and small jars. I thought I could get away with using old spaghetti sauce jars but they ended up being too big for many of the experiments. They suggest small jars like those used for jam. I ended up purchasing small canning jars which worked great.
Also, be aware that growing crystals will take a few days. This means that you will have several jars of ‘chemicals’ around so please store them out of reach of small children.
What We Learned from This Kit
There are 15 different experiments that teach basic concepts of solubility and saturation. We also performed experiments that involved the evaporation and cooling methods so that we can see the effects of temperature on particular solutions and mixtures.

I have to say that this product was fun to do with the boys. It took a couple of weeks to perform all the experiments but it was worth it at the end. By the way, we still have so much of the inventory left that we can do all the experiments again, at least 3 more times, making it worth the money spent on it.
