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. The rug can take in energy from the light, causing 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.

The table shows what happens when different types of light hit the aluminum. Based on this information, which type of light is more likely to heat up the sheet of 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.

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

Dentists use a soft, clay-like material to make a filling for a cavity. The filling stays soft under the light of the dentist’s lamp, but it hardens when the dentist shines an ultraviolet flashlight on it. Why does light from the ultraviolet flashlight harden the filling when light from the lamp does not?

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

• Because the filling material can take in energy from ultraviolet light, but not from the light from the lamp.

• Because ultraviolet light pulls energy out of the filling material, and light from the lamp does not.

• Because ultraviolet light carries hardening molecules, but light from the lamp does not.
