This is a great lesson to do with 4th or 5th graders and can be modified into all kinds of different versions!
You will need:
9x12 white paper
crayons (primary, secondary, tertiary colors are a MUST!)
Have students locate the "center" (as best they can) and start with ANY color in the spectrum. Have them draw a zig-zaggish color burst around their finger (leave the center WHITE). Going in spectrum order, they will follow this until they reach the edges of their paper.
*Sometimes the kids will line up their crayons in order to make sure they don't make a mistake, this is not necessary, but helpful!
And there ya have it! A simple, easy project that promises great results!!!
