Sunlight Makes Colors Fade


Have you ever noticed that sunlight makes colors fade? Gather brightly colored paper, several pennies or other shapes like legos or building blocks. Find a spot outside that gets several hours of sunlight and arrange them to form a pattern or design. Wait 4-6 hours and then remove the pennies or blocks and observe any changes to the paper.

Tip: If it is a windy day you may need to weight the corners of the paper under a flower pot or with rocks so it won’t blow away.

Questions to Ask: 

  • Where is the paper appearing lighter? (Around the design.) 
  • Where is the paper darker? (Under the pennies or other shapes.) 
  • Where is the sunlight affecting the paper? (Any places that are not blocked by the pennies or shapes.) 
  • What might happen if we left the paper with the shapes out for a longer time? 
  • (The paper would continue to lighten.)
