used books. A bulletin board is useful for pictures, articles, and
displays. The children can set up the science corner, with the
help of the teacher. In upper elementary grades they can build
some of the room equipment and in some cases construct simple
apparatus.
 A faucet in the room is an asset although not a necessity,
as water can be brought into the room when needed for experi-
ments. However, in planning new buildings, it is well to keep
in mind the need for water in science, art, and other activities.
 So many uses for heat are found in science that some means
of heat should be provided. If electrical outlets are accessible,
a hot plate is an excellent source and presents little danger. In
many experiments requiring little heat, candles are useful and
sufficient. An alcohol lamp may be used. This lamp can be
made by punching a hole in the top of an empty ink bottle, in-
serting a small piece of lamp wicking, and filling the bottle with
alcohol.

 A third grade science class develops and uses a science corner.
