We often take for granted the 3 common phases of
matter--solids, liquids, and gases--that occur all around us but most of us
especially take for granted the 4th state of matter, plasmas--that is
perhaps the most common form of matter found in the heart of stars and soon
to be found in your television and computer displays. Someday we might
even understand better the 'secret' 5th state of matter that even Mr.
Einstein himself was exploring in the power of his imagination!
How does salt spread
on the roads help prevent dangerous icy conditions? Why would farmers
spray oranges with water and allow them to freeze when temperatures dip
dangerously low in order to prevent a crop loss? How come if you are
baking brownies there are always directions on the box for "High Altitude"
cooking if you're in Denver, CO vs. Chicago, IL? In these activities
you will be exploring the fundamental nature of matter as it exists in its
natural states as well as its unique properties as a gas. Enjoy!
