Example Questions

Example Question #1 : Investigate How Sound Makes Materials Vibrate

What causes all sounds?

Possible Answers:

Vibrations

We do not know

Plants

Correct answer:

Vibrations

Explanation:

Vibrations cause all sounds. When something vibrates sound waves are sent through the air to our ears to hear. Without vibrations there would be no sounds.

Example Question #2 : Investigate How Sound Makes Materials Vibrate

How does sound travel to our ears?

Possible Answers:

A waving hand

Sound waves

Ocean waves

Correct answer:

Sound waves

Explanation:

Sound travels to our ears through sound waves. Once something vibrates sound waves travel through the air and our ears receive and process the sounds.

Example Question #3 : Investigate How Sound Makes Materials Vibrate

Which would be an example of something vibrating to make a sound?

Possible Answers:

Winking at a friend

Plucking a stretched rubber band

Watching a movie

Correct answer:

Plucking a stretched rubber band

Explanation:

Creating sound is done by making vibrations. Plucking a stretched rubber band would cause the object to vibrate and sound waves would be created. We would hear a sound if we listen to the rubber band.

Example Question #4 : Investigate How Sound Makes Materials Vibrate

Vibrating materials make a sound. What can we change about a sound by making it vibrate differently?

Possible Answers:

The sound cannot be changed.

How good or bad it sounds.

The volume and pitch.

Correct answer:

The volume and pitch.

Explanation:

We can change the volume or pitch of something when we change the way it vibrates. Volume is how loud or soft something sounds and pitch is how high or low the sound is. By making something vibrate more or less, faster or slower, we can change the way it sounds.

Example Question #11 : Sound And Vibration

Vibrations of materials make sounds. The vibration of an object creates sound waves that travel to our ears.

What are vibrations?

Possible Answers:

Fast back-and-forth movements

A type of small animal

A way to measure how tall something is

Correct answer:

Fast back-and-forth movements

Explanation:

Vibrations are quick back-and-forth movements that create sound waves that travel to our ears for us to hear. An example would be the vibrate setting on a cell phone or holding a ruler off a desk and flicking it so it bounces back and forth on the edge of the table.

Example Question #6 : Investigate How Sound Makes Materials Vibrate

Put a plastic ruler at the edge of the table so half of it hangs over the edge. Observe the ruler. Hold the ruler down with the palm of one hand on the table. With your other hand push the end of the ruler down and let it go. Observe the ruler again.

How does this investigation demonstrate vibrating materials making a sound?

Possible Answers:

When the ruler is moving, there is no sound, when it is still, a sound is heard.

This investigation would not help students learn about vibrations and sound.

When the ruler is still, there is no sound, when it begins to vibrate, a sound is heard.

Correct answer:

When the ruler is still, there is no sound, when it begins to vibrate, a sound is heard.

Explanation:

This investigation demonstrates the difference between a still ruler (no movement or sound) versus a ruler that has been pushed and caused to vibrate (moves up and down, and there is a sound). When the ruler is still, there is no sound, when it begins to vibrate, a sound is heard. This shows that vibrations make sounds.

Example Question #1 : Investigate How Sound Makes Materials Vibrate

How does this drum make a sound?

Gong, Grasping Week, Antique, Music

Possible Answers:

Magic

Vibrations

Waving

Correct answer:

Vibrations

Explanation:

The player would bang the drumstick on the surface of the drum, which would cause a vibration of the air in the drum against the outer material. This would travel to our ears as a sound wave so we could hear the music being played.

Example Question #11 : Sound And Vibration

The rainbow-colored lines in the back are vibrations represented as _________________. They travel to our ears after a vibrating material makes a sound.

Podcast, Microphone, Wave, Audio, Sound

Possible Answers:

vision waves

sound waves

taste waves

Correct answer:

sound waves

Explanation:

The colored lines in the background represent sound waves caused by vibrations. When an object vibrates a sound wave is created and this travels to our ear and is processed as a noise we can hear.

Example Question #1 : Investigate How Sound Makes Materials Vibrate

How is this picture similar to vibrations making a sound?

Water, Drop, Liquid, Splash, Wet, Clean, Clear, Ripple

Possible Answers:

The picture and sound both include waves.

The picture shows a drop of water which can be very loud.

The picture is not similar to sound at all.

Correct answer:

The picture and sound both include waves.

Explanation:

This picture demonstrates a drop of water rippling outwards in waves. A similar process happens with sound. Vibration causes a sound wave to be formed, and that sound wave moves outwards towards our ears so it can be processed into sound.

Example Question #11 : Sound And Vibration

Which investigation would work best to see how vibrating materials make sounds?

Possible Answers:

Hold a ruler in front of you, wave it around, and make observations

List to a popular song on the radio using your ears

Hit a tuning fork on a desk and make observations with your five senses

Correct answer:

Hit a tuning fork on a desk and make observations with your five senses

Explanation:

The best set-up of an investigation to see how vibrating materials make sounds would be to use a tuning fork. Once the metal tuning fork is hit on the best students can visually see the fork vibrating and can move their ears closer to listen. Students will be able to see and hear how the vibrations work.
