Gems
Directions:
They are the building blocks of our planet, but we rarely think about the
rocks and minerals that we see every day. Start your Web hunt for the facts
right here! Print this page to write your answers, or use a separate sheet
of paper.
When you click on the links to find the answers, you will

Every Web site that we link to was reviewed by our team. But sites change
and many sites have links to other sites which we have not reviewed. Be
sure to get permission from your parents or teacher before leaving this
site and remember the surf-safe mantra: never give out your full name or
other personal information online. You wouldn't tell a stranger this information,
and you shouldn't tell it to someone online either!
