This turned out to be a very interesting unit... Thank you National Geographic. Providentially there was an article in November's 2008 issue about the giant Selenite Crystals at theNaica mine south of Chihuahua Mexico - the article allowed me to create a very nice "hook" as I began to teach the Minerals unit. Here is a picture as we wrap-up crystals - the students built models of the crystal systems and they were put together with a display of mineral examples.
Advice? REALIA... very powerful - hand's-on very very powerful. Put the theoretical in context allow students to see the reality of what you are teaching. We are going to the Gemological Institute of America this coming week as an extra credit field trip... They will see professionals working with minerals and crystals - it honestly does not get better than this... :0 Thank you Jack for arranging this.
