▶ Use an Encyclopedia
An encyclopedia has articles about many topics These articles are arranged in alphabetical order An encyclopedia can take the form of a set of books, a Web site on the Internet, or a program on CD-ROM Regardless of the kind

FRONTIER See PIONEER LIFE
IN THE U.S FROST is one form of water It is
a pattern of ice crystals that forms when water vapor condenses on
a surface, such as a windowpane
Frost usually occurs on cold, cloudless nights when the air temperature drops below 32°F
(0 C), the freezing point of water
Frost and dew form in much
the same way At night, the drop
in temperature causes the earth
to cool As the earth gets cooler, the water condenses, forming dewdrops on surfaces Some of these dewdrops freeze when the temperature falls below freezing When the frozen droplets get larger, they become frost crystals

How to Make Frost
by Emily ChambersHave you ever noticed the frost that forms on windows
in the winter? Did you know that you can make frost?
Frost is one form of water It is made from another form
of water called water vapor All you need are ice cubes,
a plastic bag, a hammer, an empty coffee can, and salt
First, place ice cubes inside a plastic bag and seal
tightly Use a hammer to break the cubes into small
pieces Next, place a layer of ice about three centimeters
deep at the bottom of a can Then, add a thin layer of
salt on top of the ice Repeat layers of ice and salt until
the can is full The surrounding air must contain water
vapor for frost to form Finally, breathe softly on the
surface of the can to add more water vapor to the air
Now watch as frost appears on the can The frost
forms when the water vapor freezes on contact with the
cold surface of the can
