Dear Britta,

This is very interesting.  Your activity B is very similar to one that I developed and have been testing for a while.  We include more of the algebra for calculating whole-rock isochons though.  I would be interested in seeing the DVD you developed, if possible.  I am curious - what standards is this intended to address?  I only ask because I am working with several people to develop a proposal for integrating more quantitative skills into Earth science teaching at the pre-college level, and am always on the lookout for potential collaborators.
