1. If a car sits out in the sun every day for a long time, can light from the sun damage the car’s paint?

• Yes. The paint can take in energy from the light, causing it to be damaged.

• No. Light can only change things by warming them up, so it cannot damage the car’s paint.

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

• Yes. Light from the sun can pull energy out of the paint, causing it to be damaged.

Shonda is learning about a new kind of material that might be used to make new satellites, and she wonders if light can damage the material. The table below shows what happens when different types of light hit the material. Based on this information, which type of light is more likely to damage the material?

• The gamma ray light is more likely to damage the material because the gamma ray light can pull energy out of the material when it passes through the material.

• The X-ray light is more likely to damage the material because the X-ray light bounces off of the material, 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 damage the material because the material does not take in energy from either the X-ray light or the gamma ray light.

Alina notices that when she shines a desk lamp on a mirror, nothing happens. When she shines an infrared lamp on the mirror, the mirror starts to get warmer. Why does light from the infrared lamp warm the mirror when light from the desk lamp does not?

• Because the mirror can take in energy from infrared light but not from the light from the desk lamp.

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

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

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