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?
