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.
