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.

GRADE LEVEL /SUBJECT:      2            Science

PURPOSE/OBJECTIVES:  The students will experiment with
colors and discover which colors are created when the
primary colors are mixed together.

MATERIALS:  white frosting; red, blue, and yellow food
coloring; mixing bowls; 3 spoons; 3 measuring teaspoons;
graham crackers; napkins; typing paper

class.
1.  Each student will be given 2 graham crackers.
    S/he will leave one whole and break the other into
    fourths.
2.  Each student will measure 1 teaspoon of each color on
    the whole cracker.
3.  The students will predict what color will be made when
    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.
6.  The students will mix red and yellow frosting on one
    part of the other cracker using a popsicle stick.
7.  The students will  predict what color will be made when
    yellow and blue are combined.
8.  The students will mix blue and yellow frosting on one
    part of the other cracker with a popsicle stick.
9.  The students will predict what color will be made when
    red and blue and yellow are combined.
10. The students will mix red and blue and yellow frosting
    on the last part of the other cracker with a stick.
11. Enjoy!

TYING IT ALL TOGETHER:  Review what they learned by drawing
a color wheel on the board.  Students draw one on their

board with colored chalk while the others color in the
one at their desks.
