Science Projects for Kids: Spectrum of Colors

Colors at a Distance

Colors at a Distance is a science project that teaches kids about visual perception. Some colors are more easily recognized than others by the human eye.

What You'll Need:

  • Cloth strips
  • Coat hanger
  • String
  • Paper
  • Pencil

Learn About Colors at a Distance:

Step 1: Ask a friend to tie narrow strips of different-colored cloth to the bottom of a coat hanger so that the strips hang down neatly. Have your friend hang the coat hanger on a tree limb some distance from you.

Step 2: Divide a sheet of paper into 2 columns. Write your name at the top of 1 column and your friend's name at the top of the other column. Down the left side, list the colors of your strips of cloth: yellow, orange, red, green, blue, black, and so on.

Step 3: When your friend says that the coat hanger is ready to be viewed, carry the sheet of paper and your pen, and walk toward the strips of cloth. As soon as you can see a color, write the number "1" on the paper under your name and next to the color you see to indicate that you saw that color first.

Step 4: Continue numbering all the colors as you see them. Now let your friend have a turn. Do you both agree on which color you were able to see first?

Step 5: Try the experiment again at a different time of day when the light is different. Compare your results to your first experiment.

Teach kids to make a kaleidoscope that reflects the spectrum of colors. Read about this science project for kids on the next page of science projects for kids: spectrum of colors.
