Water Quest: Water Resources
The World's water is in short supply -- at least in its usable form.
Do you agree?

Great Reading
-
Check out Peter Ward's Rare
Earth. This book describes how bacteria survive in hot thermal vents, and links water in these vents to the evolution of life on earth.

Quest ("microquest"):
- Do bacteria live best in hot or cold water?
-
One seventh grader's science experiment
suggests that ice may have more bacteria than toilet water -- it won a prize. (See: "Fast-food Ice Dirtier Than Toilet Water", February, 2006, ABC/Good Morning America;
but I'd personally need to see what sort of meat and such surrounded the ice in the
refrigerator and what sort of antiseptics were used in the other; in any
case, it's generally thought that bacteria more dangerous to us is that which
survives between room and body temperature.)
Quest ("macroquest"):
- Learn about a watershed.
-
Learn about the Mississippi, and find out about Katrina's effects at American Rivers' and the U.S. Geological Survey's sites. Learn about other watershed projects around the nation at the Interactive Watersheds' links. Then map your
own local watershed! Finally, investigate your watershed's ecosystem, and check it for signs of danger. (Eventually this page will link to kits that help evaluate/test water.)
