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.

    and 10-12 grades. You

    can contact either myself

    ([log in to unmask]) ,
    >we will send out DVD's and posters.
    >In addition, if someone wants to adopt the
