This Mini-Teach is designed for K-6. This lesson is designed to introduce
primary and secondary colors of light.

Materials Needed:

Activity 1

Paper Plates
Pegs or Pencils
Rulers or Protractors

Activity 2

Red, blue, and green filters
Overhead Projector
Three Mirrors

Activity 3

Bubble Solution
Bubble Wands or drinking straws for each student

Activity 4

A Flag that has green and black strips, black stars, and a yellow background
where the white is suppose to be.


Activity 1 (Circle Wheel)

With the scissors, cut the outer circle off of paper plate, divide the plate
into eight equal sessions and color it red, blue, yellow, purple, white, green,
indigo, and orange. Put a hole in the center of the circle, push the pencil or
peg through the hole and attach the tape to back of plate. The purpose of the
peg or pencil is to spin the plate.

Activity 2 (Color Demonstration)

The object to this activity is to show how the primary colors (red, blue, and
green) are separate colors but if you mix these colors you make secondary
colors. Then if you mix secondary colors you make white.

Activity 3 (Bubbles)

The students use the bubble to first blow and observe. The students are then
asked to make a list of all colors that they observe in the bubbles. The
students are then asked what kind of light they see hitting the bubbles. They
should say they see white light passing through the bubbles causing the bubbles
to appear different colors.

Activity 4 (Is Seeing Believing)

The students are given a flag that is black, green, and yellow. The students
are then asked to stare at the star in the bottom right hand corner for 30
seconds and then turn the card over to the white side and observe what happens.
The students should see the pinkish-red, white, and blue american flag. The
colors appear because the eye cones get tied and see complementary colors of the
original colors. Example: White light minus green gives pinkish-red, and White
light minus yellow gives blue.

Performance Assessment:

The students are then asked to answer in written form "What happens when you add
blue, yellow, green, and pink together?" They should answer White.
