Dear resourceful listserv members,
Can someone send me a recipe for a plaster of paris/sand matrix to use
in our investigation cart "fossil dig"? The previous education director
developed this fun activity but did not leave the recipe for the matrix
(at least in all the places I looked). At present our fossils have
already been "dug" so we need to freshen up and re-bury our fossils.
Thanks,
Wendy
