Some of the beaches in Panama are almost totaly iron, on hot days you
can get blisters running across the beach to the sea.  Maybe if there
is time the studen can correspond with other student via email and
either get samples from other beaches or get the other student to do
the experimet and send the results.


Warmly,

Angel
