Sound is produced when an object vibrates and transfers energy through a medium.

2. QuestionMultiple choice

A speaker makes a sound louder without changing its pitch. What wave property increased?

Please select an answer first.

Correct answer: B

The correct answer is Amplitude.

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: Greater amplitude means more energy in the sound wave and is heard as greater loudness.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

Greater amplitude means more energy in the sound wave and is heard as greater loudness.

3. QuestionMultiple choice

A violin string vibrates more times per second than a bass string. How will its pitch compare?

Please select an answer first.

Correct answer: C

The correct answer is The violin string will produce a higher pitch..

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: Frequency is the number of vibrations per second, and higher frequency produces higher pitch.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

Frequency is the number of vibrations per second, and higher frequency produces higher pitch.

4. QuestionMultiple choice

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: Electromagnetic waves can travel through a vacuum, unlike mechanical waves such as sound.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

Electromagnetic waves can travel through a vacuum, unlike mechanical waves such as sound.

5. QuestionMultiple choice

A light ray strikes a mirror and changes direction. What process occurred?

Please select an answer first.

Correct answer: A

The correct answer is Reflection.

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: Reflection occurs when light bounces from a surface.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

Reflection occurs when light bounces from a surface.

6. QuestionMultiple choice

A pencil appears bent when part of it is placed in water. What causes this appearance?

Please select an answer first.

Correct answer: B

The correct answer is Refraction as light moves between water and air.

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: Light changes speed and direction when it moves between materials with different optical properties.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.
