Scenario: Sarah is conducting an experiment in her science class. She shines a flashlight on a black piece of paper and notices that the paper becomes warmer after a few minutes. What is happening in this scenario?
A) The paper is emitting light energy.
B) The paper is absorbing energy from the light.
C) The flashlight is absorbing energy from the paper.
D) The paper is reflecting light energy.
B) The paper is absorbing energy from the light.
Scenario: Jason places a glass of water in direct sunlight for an hour. After some time, he observes that the water has become warm. Which statement best explains this observation?
A) Sunlight is reflecting off the water.
B) Sunlight is absorbed by the water, causing it to gain energy.
C) Sunlight is converting into water molecules.
D) Sunlight is evaporating the water.
B) Sunlight is absorbed by the water, causing it to gain energy.
Scenario: Emily is investigating the effect of light on different colors of fabric. She exposes a red piece of fabric and a blue piece of fabric to sunlight for the same duration. Afterward, she notices that the red fabric feels warmer than the blue fabric. What can Emily conclude from this observation?
A) Red fabric absorbs more light than blue fabric.
B) Blue fabric reflects more light than red fabric.
C) Red fabric emits more light than blue fabric.
D) Blue fabric absorbs more light than red fabric.
A) Red fabric absorbs more light than blue fabric.
Scenario: Alex is experimenting with different types of materials in his science class. He shines a flashlight on a metal spoon, a wooden spoon, and a plastic spoon for one minute each. Afterward, he observes that the metal spoon feels warmer than the other two spoons. What can Alex infer from this experiment?
A) Metal absorbs less light energy than wood and plastic.
B) Metal reflects more light energy than wood and plastic.
C) Metal emits more light energy than wood and plastic.
D) Metal absorbs more light energy than wood and plastic.
D) Metal absorbs more light energy than wood and plastic.
Scenario: Lisa places a glass jar filled with water and a glass jar filled with oil under a lamp for an hour. Afterward, she observes that the water in the jar feels warmer than the oil. What is the most likely reason for this temperature difference?
A) Water absorbs more light energy than oil.
B) Oil reflects more light energy than water.
C) Water emits more light energy than oil.
D) Oil absorbs more light energy than water.
A) Water absorbs more light energy than oil.
Which of the following best describes how light travels?
a) In a zigzag path
b) In a curved path
c) In a straight line
d) In a spiral path
c) In a straight line
What happens when a light wave hits a material?
a) It disappears
b) It changes direction randomly
c) It can be absorbed, transmitted, or reflected
d) It splits into multiple waves
c) It can be absorbed, transmitted, or reflected
When light is transmitted through a material, what does it mean?
a) The material absorbs all the light
b) The material reflects all the light
c) The light passes through the material
d) The material changes color
c) The light passes through the material
Which of the following is true about materials and light transmission?
a) All materials transmit all types of light equally
b) Materials transmit or reflect all types of light equally
c) Materials transmit or reflect some types of light and not others
d) Materials always absorb all types of light
c) Materials transmit or reflect some types of light and not others
What happens to the energy of light when it is transmitted through a material?
a) The energy is absorbed by the material
b) The energy changes color
c) The energy is not absorbed, and the material remains unchanged
d) The energy causes the material to become transparent
c) The energy is not absorbed, and the material remains unchanged
Imagine you’re standing in a dark room with a flashlight. You turn it on and point it towards a mirror on the wall. What do you expect to see happen to the light from the flashlight? Why does this happen?
When the light from the flashlight hits the mirror, the light will be reflected off the mirror. The reflected light will appear to “bounce off” the mirror and hit another wall in the dark room.
You’re wearing a white T-shirt outside on a sunny day, and your friend is wearing a black T-shirt. After a while, you notice that your friend feels hotter than you do. Explain why this might be the case, considering the colors of your shirts.
The white t-shirt reflects more sunlight, while black absorbs more sunlight. When the black t-shirt absorbs sunlight, it is absorbing energy from the sun which causes it to warm up. Since the white t-shirt is reflecting more sunlight, it is not absorbing as much and is therefore not warming up as much as the black t-shirt.
What happens when different types of light interact with a material?
A) They all produce the same effect
B) They can change the material in different ways
C) They pass through the material without any interaction
D) They deactivate the material’s properties
B) They can change the material in different ways
Which statement accurately describes the relationship between light sources and emitted types of light?
A) A light source emits only one type of light
B) A light source emits all types of light equally
C) A light source can emit more than one type of light
D) A light source emits light based on the material it interacts with
C) A light source can emit more than one type of light
What distinguishes different types of light from each other?
A) Their intensity
B) Their color
C) Their wavelength
C) Their wavelength
