The Beauty of Petroglyphs (also called rock engravings)

This site is inteanded to inform students about an important topic as well as create conversation in and out of the classroom.

The link to the articles posted under learn more in the process section may be too far above some students reading level I recommend being available for extra help with this and not to let students feel frustrated with this.

I also recommend adding to the online discussion yourself as to add ideas and spark more chatter. The thread should be allowed to be contributed to for at least one week so students have ample oppurtunities to participate.
