OVERVIEW:  Red, yellow, and blue are called primary colors.
Every other color can be produced by mixing different
combinations of these colors.  Red and yellow make orange.
Red and blue make purple.  Yellow and blue make green.  The
newly created colors are orange, purple, and green.  These
colors are called secondary colors.

    red and blue are combined.
4.  The students will mix red and blue frosting on one part
    of the other cracker using a popsicle stick.
5.  The students will predict what color will be made when
    red and yellow are combined.

TYING IT ALL TOGETHER:  Review what they learned by drawing
a color wheel on the board.  Students draw one on their
piece of paper.  Students help fill in the wheel on the
board with colored chalk while the others color in the
one at their desks.
