Look at the objects in the picture. Why are you able to see the sand?
The sand reflects light.
The sand absorbs light.
The sand emits light.
The sand refracts light.
A student did an investigation on light brightness. She measured the light intensity with a light meter at different distances from a flashlight.
A graph of her data is shown below.
What is the best claim she can make from the data in her investigation?
As the distance from the flashlight increases, the light intensity increases.
As the distance from the flashlight increases, the light intensity remains the same.
As the distance from the flashlight decreases, the light intensity increases.
As the distance from the flashlight decreases, the light intensity remains the same.
A group of students shined a red, blue and green light on a screen.
What is the best scientific argument to explain the white color in the middle?
White light contains red, blue and green light.
The paper behind the light absorbs white.
White light is reflected by the flashlights.
The paper absorbed the light from the flashlights.
A student observes two stars at night. Star A appears much brighter than star B.
What is the best claim she can make from the evidence she observed?
Star A gives off more light than star B.
Star A is closer than star B.
Star B is closer than star A.
Star A may give off more light or it may be closer.
The picture shows white light being shined through two glass prisms.
Which of the claims below is best supported by the evidence in the picture?
The glass contains different colors of light.
The glass changes the light into different forms of energy.
White light contains different colors of light.
White light changes into different forms of energy when it bends.
A student observed that light spreads out as it leaves a light source as shown in the picture.
Which of the following best explains what occurs because the light spreads out?
Light appears brighter closer to the source.
Light appears dimmer closer to the source.
There is more light as you get farther from the source.
There is less light as you get closer to the source.
Jim drew the diagram to help him model how he thought light allowed him to see that the apple is red.
Which of the following claims must be true for the apple to appear red?
The apple must absorb red light.
The apple must produce red light.
Sunlight must contain red light.
Sunlight must contain green light.
A student made observations of an unknown material. Below are the notes she wrote in her notebook from her observations.
-The material was red.
-When I held it up to the window, I could see light through it.
-I could see things through it, but they looked blurry.
-It was two inches thick.
What can you conclude from the observations?
The material was translucent because it scattered the light.
The material was transparent because she could see through it.
The material was translucent because she could see through it clearly.
The material was transparent because it scattered light.
The diagram shows a person looking at the moon at night.
Why does he see a full moon?
The moon gives off light at night.
Sunlight is reflected by Earth.
Sunlight is reflected by the moon.
The moon’s light is absorbed by Earth.
Here is a picture of a group of students around a campfire.
Why are the students able to see the campfire?
The light is reflected off their faces.
The light is given off by the fire.
The light is absorbed by the logs.
The light is reflected off the fire.
Sarah took the picture of a rainbow below after a rainstorm.
What is the best claim she can make for the colors that appeared?
Sunlight contains different colors.
Rain contains different colors.
The sky is made up of different colors.
The sky absorbs many different colors.
Below is a model showing how a person sees a flower.
What is the source of the light the person sees when he sees the flower?
The flower
The sun
His eyes
His brain
Sally put her spoon in the glass of water shown below.
Which of the following best explains why the handle appeared broken?
The light was reflected off the spoon.
The light was refracted by the spoon.
The light was refracted by the water.
The light was reflected by the water.
A scientist measured the brightness of a light at several different distances from a light source. Below is the data he collected from his investigation.
Which of the following is the best claim the scientist can make from this data?
Light appears less bright when you are closer to the source.
Light appears brighter when you are closer to the source.
As distance increases light brightness increases.
As distance decreases light brightness decreases.
A student drew the model below to show why a fish in water might appear to be in a different place than it actually is.
What property of light was he most likely modeling?
Reflection
Absorption
Refraction
Transparency
A student drew the model below to help explain what happens when a person sees a red shirt.
Which of the following best explains the model?
Red light is reflected, and the other colors are absorbed.
Red light is absorbed, and the other colors are reflected.
White light is refracted, and red light is absorbed.
White light is absorbed, and red light is refracted.
A group of students did an investigation in which they shined light beams on four different objects. They made the following drawings to show what the light did when it hit the objects.
Which one of the objects is most likely transparent?
A
B
C
D
The model below shows what happens when red, blue, and green light strike a red opaque object.
Which of the following best explains what happens to the green light?
It is absorbed and changed to another form of energy.
It is absorbed and later reflected as blue light.
It is refracted as green light.
It is reflected as green light.
A student was asked to observe the objects below.
Which of the following claims is best supported by the evidence?
