Jayden says that the dentist can shine a special light on his teeth that will make his teeth become whiter. Can light change Jayden’s teeth?
Yes. Jayden’s teeth can take in energy from the light, causing them to become whiter.
Yes. Light can pull energy out of Jayden’s teeth, causing them to become whiter.
No. Light can only change things by warming them up, so it cannot cause Jayden’s teeth to become whiter.
No. Light is not a physical thing, so it cannot change physical things like teeth.

Lighter or darker skin tones are caused by...
the amount of sunlight someone receives.
how close someone lives to the equator.
the amount of light waves someone receives.
the amount of melanin in skin cells.
What is the relationship between melanin, genetic material, and skin cancer?
Melanin absorbs UV light which protects genetic material from developing skin cancer.
Melanin reflects UV light which protects genetic material from developing skin cancer.
Melanin converts UV light into energy which protects genetic material from developing skin cancer.
UV light is transmitted through melanin which protects genetic material from developing skin cancer
