A "native metal" is one found in metalic form in it's natural state. Gold
(in the form of nuggets) is the one most people have heard of, though copper,
silver, and platinum also occur.

There are several types of molds. Green sand molds, oil sand molds, carved molds
from soapstone and cuttlebone, lost wax investment molds, ceramic shell molds,
die molds, etc.

Most of the answers are in the merit badge book, available from your local
council office -- if you tell them you'll be teaching the badge, you may even
be able to talk them into lending you a copy. Some libraries also carry the 
books, though they tend to be out of date.
