Mineral Information Institute has many resources available for your mineral and mining instruction. The above graphic is one such piece of fascinating information. (Here's the printable baby.)
The information is based around the central theme that minerals and natural resources are necessary for life and in fact find their way into nearly every aspect of our lives. A Bright Smile from Toothpaste & Minerals and How Many Minerals Does it take to Make a Light Bulb? are great examples of minerals found in places your students might not expect.
