Coal Garden

Kellie Wood reminded me that I had promised to post a recipe for a coal garden to our project blog.

I have done these crystal gardens many times and they work every time and the students love to watch it grow and change. This can stimulate so many lessons. Students can explore the chemistry behind the changes taking place on the coal as the crystals form. Another interesting discussion is the "growth" of the crystals. Students can be asked to defend whether the crystals are alive based on the growth.

Other than the coal, the ingredients are available at most grocery stores. If you are younger, you may have never used bluing in laundry. However, bluing is available in laundry areas of many grocery stores, especially older stores.

The easy instructions are HERE.
