Grade 4 Light and Sound Practice Test

Build Grade 4 Science skills with five 10-question practice tests on light sources, shadows, reflection, refraction, sound vibrations, pitch, volume, and hearing safety.

Light and Sound Practice Tests

These Grade 4 Science practice tests help students explain how light and sound carry energy and interact with materials. Students identify light sources, shadows, transparent and opaque materials, reflection, refraction, sound vibrations, pitch, volume, echoes, and hearing safety.

Skills covered

  • Identifying light sources and materials that transmit or block light
  • Explaining shadows, reflection, and refraction
  • Describing sound as a result of vibrations
  • Comparing pitch and volume
  • Explaining echoes and sound paths
  • Applying light and sound ideas to instruments, communication, and safe designs

How to use these practice tests

For light questions, identify the source and notice whether light is blocked, reflected, or bent. For sound questions, identify what vibrates, how the vibration travels, and whether the sound is high or low in pitch or loud or soft in volume.

1. QuestionMultiple choice

Which classroom design would best reduce an echo?

Please select an answer first.

Correct answer: A

The correct answer is Add soft curtains and fabric wall panels..

  1. Observe the situation: Look for a light source, a blocked or reflected ray, a vibration, or a sound path.
  2. Apply the science rule: Soft materials absorb sound and reduce reflected echoes.
  3. Confirm the answer: The correct choice is Add soft curtains and fabric wall panels..

Soft materials absorb sound and reduce reflected echoes.

2. QuestionMultiple choice

What is needed to read a sign in a dark room?

Please select an answer first.

Correct answer: B

The correct answer is Light must travel from a source to the sign and then to the eyes..

  1. Observe the situation: Look for a light source, a blocked or reflected ray, a vibration, or a sound path.
  2. Apply the science rule: We see the sign when light illuminates it and reflected light reaches the eyes.
  3. Confirm the answer: The correct choice is Light must travel from a source to the sign and then to the eyes..

We see the sign when light illuminates it and reflected light reaches the eyes.

3. QuestionMultiple choice

Which object would make the clearest shadow in sunlight?

Please select an answer first.

Correct answer: C

The correct answer is A solid metal toy.

  1. Observe the situation: Look for a light source, a blocked or reflected ray, a vibration, or a sound path.
  2. Apply the science rule: A solid opaque object blocks sunlight and forms a clear shadow.
  3. Confirm the answer: The correct choice is A solid metal toy.

A solid opaque object blocks sunlight and forms a clear shadow.

4. QuestionMultiple choice

Which action helps protect hearing at a loud concert?

Please select an answer first.

Correct answer: D

The correct answer is Wear earplugs or earmuffs..

  1. Observe the situation: Look for a light source, a blocked or reflected ray, a vibration, or a sound path.
  2. Apply the science rule: Ear protection reduces the sound energy reaching the ears.
  3. Confirm the answer: The correct choice is Wear earplugs or earmuffs..

Ear protection reduces the sound energy reaching the ears.

5. QuestionMultiple choice

Which observation shows that sound can travel through a solid?

Please select an answer first.

Correct answer: A

The correct answer is A person hears a tap through a table when an ear is placed against it..

  1. Observe the situation: Look for a light source, a blocked or reflected ray, a vibration, or a sound path.
  2. Apply the science rule: The tapping vibration travels through the solid table to the listener.
  3. Confirm the answer: The correct choice is A person hears a tap through a table when an ear is placed against it..

The tapping vibration travels through the solid table to the listener.

6. QuestionMultiple choice

A wave makes a rope move up and down many times each second. What can be inferred?

Please select an answer first.

Correct answer: B

The correct answer is The rope is vibrating quickly and can carry energy..

  1. Observe the situation: Look for a light source, a blocked or reflected ray, a vibration, or a sound path.
  2. Apply the science rule: Repeated motion shows vibration, and the wave transfers energy through the rope.
  3. Confirm the answer: The correct choice is The rope is vibrating quickly and can carry energy..

Repeated motion shows vibration, and the wave transfers energy through the rope.

7. QuestionMultiple choice

Which statement correctly compares a high-pitched sound with a low-pitched sound?

Please select an answer first.

Correct answer: C

The correct answer is The high-pitched sound has faster vibrations..

  1. Observe the situation: Look for a light source, a blocked or reflected ray, a vibration, or a sound path.
  2. Apply the science rule: Pitch depends on vibration rate, with faster vibrations producing higher pitch.
  3. Confirm the answer: The correct choice is The high-pitched sound has faster vibrations..

Pitch depends on vibration rate, with faster vibrations producing higher pitch.

8. QuestionMultiple choice

Which conclusion is supported by a mirror experiment?

Please select an answer first.

Correct answer: D

The correct answer is A smooth mirror can change the direction in which light travels..

  1. Observe the situation: Look for a light source, a blocked or reflected ray, a vibration, or a sound path.
  2. Apply the science rule: The reflected ray leaves the mirror in a new direction.
  3. Confirm the answer: The correct choice is A smooth mirror can change the direction in which light travels..

The reflected ray leaves the mirror in a new direction.

9. QuestionMultiple choice

Which statement best explains a difference between light and sound?

Please select an answer first.

Correct answer: A

The correct answer is Light can travel through empty space, while sound needs a medium..

  1. Observe the situation: Look for a light source, a blocked or reflected ray, a vibration, or a sound path.
  2. Apply the science rule: Light from the Sun crosses space, but sound requires matter to vibrate.
  3. Confirm the answer: The correct choice is Light can travel through empty space, while sound needs a medium..

Light from the Sun crosses space, but sound requires matter to vibrate.

10. QuestionMultiple choice

Which investigation would best test how distance affects sound volume?

Please select an answer first.

Correct answer: B

The correct answer is Play the same sound and measure its volume at several distances..

  1. Observe the situation: Look for a light source, a blocked or reflected ray, a vibration, or a sound path.
  2. Apply the science rule: Keeping the sound the same while changing distance makes the test useful.
  3. Confirm the answer: The correct choice is Play the same sound and measure its volume at several distances..

Keeping the sound the same while changing distance makes the test useful.
