A Simple Way to See Color Addition

This simple craft creates a personal demonstration for students to see color addition in action.

black construction paper, cut into squares approx. 2"

red green and blue label dots

Put the dots on the squares in a way that they slightly overlap when comparing one dot to the other. This picture shows a front and back side facing the same direction.

Bend two opposite edges, making triangles that go opposite ways.

That's it! Hold the "color mixing apparatus" as shown and blow over a bent edge that faces towards you. As it spins, the two colors mix to create a secondary color (yellow, cyan, or magenta).
