Example Question #8 : Provide Evidence Relating Sound And Vibrations
Sadie and Allison have to plan a science investigation that will provide evidence of the relationship between sound and vibrations. Which plan would be the best choice?
Yell very loudly across a football field. Observe what happens.
Pluck a rubber band that is wrapped around an empty tissue box. Observe what happens.
Play the radio quietly, then turn it up loudly. Observe what happens.
Pluck a rubber band that is wrapped around an empty tissue box. Observe what happens.
The best plan to show a relationship between sound and vibrations would be to pluck the rubber band wrapped around an empty tissue box. When plucked students can observe the movement of the rubber bad and hear the sound that is produced. This would be evidence that sound and vibrations are related.
Example Question #9 : Provide Evidence Relating Sound And Vibrations
Sound and vibrations are separate and have no relationship.
False
True
False
This statement is not true. Sound and vibrations are very much related, and they have a cause and effect relationship. Sound can cause vibrations, and vibrations can create sound.
Example Question #10 : Provide Evidence Relating Sound And Vibrations
Evidence from investigations can show the relationship between sound and vibrations.
False
True
True
One of the main ways to show if something is supported or not is to gather evidence. When conducting an investigation, data is collected, and scientists can make conclusions about what happened. Planning and conducting an investigation is a great way to show the relationship between sound and vibrations.
Example Question #11 : Sound And Vibration
What causes all sounds?
Plants
We do not know
Vibrations
Vibrations
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 #12 : Sound And Vibration
How does sound travel to our ears?
A waving hand
Ocean waves
Sound waves
Sound waves
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 #13 : Sound And Vibration
Which would be an example of something vibrating to make a sound?
Watching a movie
Plucking a stretched rubber band
Winking at a friend
Plucking a stretched rubber band
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 #14 : Sound And Vibration
Vibrating materials make a sound. What can we change about a sound by making it vibrate differently?
The volume and pitch.
How good or bad it sounds.
The sound cannot be changed.
The volume and pitch.
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 #1 : Investigate How Sound Makes Materials Vibrate
Vibrations of materials make sounds. The vibration of an object creates sound waves that travel to our ears.
What are vibrations?
A type of small animal
Fast back-and-forth movements
A way to measure how tall something is
Fast back-and-forth movements
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 #16 : Sound And Vibration
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?
When the ruler is still, there is no sound, when it begins to vibrate, a sound is heard.
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.
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 #17 : Sound And Vibration
How does this drum make a sound?
Vibrations
Waving
Magic
Vibrations
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.
