What does this piece of evidence from the "What is Melanin?" article prove?

• If there is more melanin in skin cells, less UV light reaches genetic material.

• UV light is attracted to skin cells.

• If there is less melanin in skin cells, less UV light reaches genetic material.

• Melanin does not play a role in protecting genetic material from UV light

Maya wonders which types of light could heat up a sheet of aluminum. The table below shows what happens when different types of light hit the aluminum.

• The X-ray light is more likely to heat up the aluminum because the X-ray light can pull energy out of the aluminum when it passes through the aluminum.

• The ultraviolet light is more likely to heat up the aluminum because the ultraviolet light bounces off the aluminum, which means that it has more energy.

• There is no way to know because they are two different types of light, and different types of light can change a material in different ways.

• Neither type of light is likely to heat up the aluminum because the aluminum does not take in energy from either the X-ray light or the ultraviolet light.

These graphs show the wavelength and amplitude of light coming from three lasers. Could any of these lasers be giving off a different type of light?

• Yes. Laser 2 is giving off a different type of light because Laser 2 has a different wavelength than Lasers 1 and 3.

• Yes. Laser 3 is giving off a different type of light because Laser 3 has a different amplitude than Lasers 1 and 2.

• Yes. All three lasers must be giving off different types of light because every light source gives off its own type of light.

• No. All three lasers must be giving off the same type of light because all three are lasers, and the same kind of light source gives off the same type of light.

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.

Will saw a special type of plastic that would melt and become a liquid when it was placed in the sun, but it would not melt when placed under a desk lamp. Why does light from the sun melt the plastic when light from the desk lamp does not?

• Because the plastic can take in energy from the light from the sun but not from the light from the lamp.

• Because light from the sun carries heat molecules, and light from the desk lamp does not.

• Because light from the sun pulls energy out of the plastic, and light from the desk lamp does not.

• Because the sun gives off a type of light that carries energy, and light from the desk lamp does not.

Aaliyah has a special type of paper that can permanently change color. She wonders whether light can cause the paper’s color to change. The table below shows what happens when different types of light hit the paper. Based on this information, which type of light can cause the paper to change color?

• The infrared light can cause the paper to change color.

• The X-ray light can cause the paper to change color.

• The ultraviolet light can cause the paper to change color.

• Any of these types of light can cause the paper to change color, because all light carries energy that can cause materials to change.

Your friend says that he heard about some rocks that would glow when they were put under a certain kind of light. Can light cause rocks to glow?

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

• No. Light can only change things by warming them up, so it cannot cause the rocks to glow.

• Yes. Light can pull energy out of the rocks, causing them to glow.

• Yes. Rocks can take in energy from the light, causing them to glow.

Paintings in museums have to be kept away from ultraviolet light. Ultraviolet light will cause the paint to fade, but the overhead lamps in a museum won’t cause the paint to fade. Why does the ultraviolet light cause the paint to fade when light from the overhead lamps does not?

• Because ultraviolet light pulls energy out of the paint, and light from the overhead lamps does not.

• Because ultraviolet light carries energy, and light from the overhead lamps does not.

• Because the paint can take in energy from ultraviolet light but not from the light from the overhead lamps.

• Because ultraviolet light carries heat molecules, and light from the overhead lamps does not.
