A rug sits in a sunny place on the floor for a long time. Kiara thinks that light from the sun can cause the rug’s color to fade over time. Can light from the sun cause the rug’s color to fade?

• No. Light is not a physical thing, so it cannot change physical things like rugs.

• No. Light can only change things by warming them up, so it cannot cause the rug’s color to fade.

• Yes. Light from the sun can pull energy out of the rug, causing the rug’s color to fade.
