• C. Light travels in waves that moves through objects.

• D. Light travels only through air.

Which word below describes what will happen to the light as it hits the mirror?

• absorption

• reflection

• refraction

John and Ben want to carry out an investigation to determine objects that reflect light. What are some items they should choose for their investigation that would BEST reflect light?

• black construction paper, a mirror, and aluminum foil

• black construction paper, water, and a mirror

• a mirror, aluminum foil, and water

• a mirror, black construction paper and water

Students made mirror mazes using flashlights, mirrors, and shiny metal cans. Which statement below would best describe what is learned during this investigation?

• The light travels in a straight path no matter what material it hits.

• The light absorbs into the mirrors.

• When the direction of the light source is changed, the mirror reflection angle will not change.

• When the angle of the mirror is changed, the direction of the light changes.

Why would a person not wear dark colored clothes on a hot, sunny, summer day?

• Dark clothing refracts sunlight, so it makes the person warmer.

• Dark clothing reflects sunlight, so it makes the person warmer.

• Dark clothing absorbs sunlight, so it makes the person warmer.

• Dark clothing dissolves sunlight, so it makes the person warmer.

Students go outside to observe a rainbow that appears after a rain storm. What would be an explanation a student could give as to why the rainbow formed?

• Sunlight is absorbed by the raindrops.

• Sunlight is refracted by the raindrops.

• Sunlight is dissolved by the raindrops.

• Sunlight is evaporates by the raindrops.

Students are completing investigations to show how light is refracted. Which is an example that would show this?

• An investigation with a flashlight pointing at a glass of water and observing the path of the light.

• An investigation with a flashlight pointing at a mirror and observing the path of light.

• An investigation with a flashlight pointing at a piece of cardboard and observing the path of light.

• An investigation with a flashlight pointing at a book and observing the path of light.
