exhibit he distributed samples of a mineral that can be found
near Sandy’s. It has no name, but is made up of calcium sulfate.
He also displayed calcite, from Laie, that is soley made of
DeCarlo, an oceanography professor at the University of Hawai‘i-
Maona, uses his knowledge of chemical structures to track down
his treasures. He hopes to some day open the experience of rock
hounding to his students by offering a class about it. DeCarlo
feels that it would be much easier teaching chemistry if students
could have a way, to apply it.
Established in 1970, the non-profit educational organization,
