#17 - Gold
September/October 2008
In this issue of KNOW we're "going for gold." We're taking a close look at this glittery mineral, which people the world over cherish. You'll see the many ways that we use gold and what makes it one of the world's most valuable metals. We've included the ABCs of Gold, too. It's a fun way to explore gold, from Aurum to Zimbabwe. Elsewhere in the magazine you can meet river dolphins that lure the ladies using bouquets of weeds, dogs that sniff out Arctic seals, and, just in time for school, the science behind erasers. Eureka! Issue 17 is available now. Check it out!
