Geology Class Part I

Thanks to EB, we all learned a lot in this first geology class. Here the kids are creating a model of the earth in chalk, showing the core, outer core, mantel, and crust. We also learned about the Mohs scale for mineral hardness; how have I lived this long without learning such cool stuff? Lots of hands-on activities and experiments, courtesy of the California Academy of Sciences materials and EB's wonderful facilitation.
