[Rockhounds] Geology demostrations for preschools

[Brett Whitenack]

I work in a small museum and every year we have what we call the Preschool Jamboree. We invite all of the preschools in town to bring their students in and give a short presentation on some topic that coincides with a feature exhibit in the museum.
 
This year we are featuring Wonders of the Earth. I want to do some short demonstrations that deal with earth science but are geared towards 3-4 year olds. I have some fluorescent minerals to show, pumice-the rock that floats, and we will break a small geode to give to the class. 
 
Do the members of the list have any other suggestions as to any demonstrations that I could use? Also, is there anyone out there who would have a cheap source for small (1 1/2 - 2 inch diameter) geodes? Any suggestions would be most appreciated.
 
While I have your attention I want to say what a great list this is. I have learned much and enjoy reading all the topics the list members present with each post.
 
Thank you
 
Brett W.
