Science of Art: Spinning to Make Colors
Materials:
Pencil, compass (or cookie cutter), White Card stock, scissors, markers or crayons, sharp pencil or wooden skewer
Procedure:
- Use a pencil and a compass or a circle cookie cutter to make circle shapes on white card stock. Cut them out with scissors.
- Divide the circles into equal sections and decorate each section with different colors.
- Push a sharp pencil or stick through a hole in the center of each circle.
- Spin the spinner as fast as you can on a tabletop and watch the different colors merge. If you color a spinner with the colors of a rainbow, it may appear white when you spin it.
Result:
The spinner is turning so fast that instead of seeing separate colors, our eyes see the mixture.
Explanation:
White light is made up of the colors of the rainbow, so a spinner decorated with these colors appears white. Look closely at a color TV or the photographs in a book. The pictures are made up of lots of tiny colored dots. By seeing books and tvs from a distance, the dots seems to mix together and make colors.
