PURPOSE : To observe the camouflaging technique of animals.

MATERIALS : Red transparent plastic folder
                           Pale yellow crayon
                           White typing paper


  • Draw a bird on the white paper with the yellow crayon.
  • Cover the drawing with the red folder.
RESULTS : The yellow bird disappear.

WHY ? The yellow bird and red folder both are reflecting light to your eyes. The red is not a pure color, but has some yellow in it. This yellow blend in with the yellow from the bird drawing, and your eye is not sensitive enough to separate them. Animals that have similar colorations as their environment are often camouflaged, hidden from prey. The stalking animal’s eyes cannot distinguish the colors enough to separate its meal from the leaves.
