Example Questions
Example Question #21 : Sound And Vibration
Pat's class is given an empty metal can with plastic wrap stretched across the top secured with a rubber band. His teacher sprinkles salt on the top of the plastic wrap. He is given a tuning fork and told to strike it on the desk and touch it to the side of the can. The rice starts to jump and he hears a sound. Why is this happening?
The tuning fork is magic so it allows the rice to move and make sounds.
Vibrating materials (like the fork and can) make sounds and cause other vibrations.
There is no relationship between the vibrations and sound.
Vibrating materials (like the fork and can) make sounds and cause other vibrations.
The salt moved because of the vibrations of the tuning fork. When struck on the desk it begins vibrating which makes a quiet sound. When the tuning fork is placed against the can it gets louder because the can is also vibrating. This causes the rice to start "jumping" because it is also vibrating. Pat will hear the tuning fork, metal can, and the sound of the rice hitting the plastic wrap because of the vibrations.
Example Question #2 : Investigate How Vibrating Material Makes Sound
What does it mean if something vibrates?
It moves quickly back-and-forth
It moves slowly one time
It is a type of dance move
It moves quickly back-and-forth
Vibrating means small, quick back-and-forth movements. When you pluck a rubber band, it vibrates, when we talk our vocal cords vibrate, everything vibrates when it makes sounds.
Example Question #3 : Investigate How Vibrating Material Makes Sound
A vibrating object can produce sound.
True
False
True
This is a true statement. Vibrating materials do create sounds. If you think if the strings of a guitar, when strummed the strings vibrate and create the sounds. Sound comes from vibrations.
Example Question #4 : Investigate How Vibrating Material Makes Sound
What happens when materials vibrate?
Ocean waves are created and move through the air.
Sound waves are created and move through the air.
Nothing happens when materials vibrate.
Sound waves are created and move through the air.
When a material vibrates sound waves are produced and travel through the air. Without vibrations, there would be no sound.
Example Question #5 : Investigate How Vibrating Material Makes Sound
Ms. Dube's class is experimenting with science today. At the Tuning Fork Station, students hit the tuning forks on the side of a cup. The vibration causes _________.
the cup to fall
an earthquake
sound
sound
The vibration of the tuning fork causes sounds to be heard. When an object or material vibrates it creates sound waves. Those waves travel through the air and our ears receive and process the noises.
Example Question #6 : Investigate How Vibrating Material Makes Sound
How does hitting a drum produce sound?
The drum and air vibrate.
The drum does not produce sound.
The drum has speakers and a radio attached.
The drum and air vibrate.
A drum produces sound when it is struck with a hand or object because the skin or outer covering vibrates. The air vibrates and sound waves move through the air producing the banging noises we hear with drums.
Example Question #7 : Investigate How Vibrating Material Makes Sound
Students place their hands on the front of their throat. The teacher asks them to hum softly and write down what they feel. The teacher asks them to hum louder and write down what they feel. The teacher asks them to be silent and write down what they feel.
Why was there no humming sound when there was no vibration?
There is no way to tell why there was no humming.
The student was not trying hard enough.
The material must vibrate to make a sound.
The material must vibrate to make a sound.
When materials (including our vocal cords) vibrate, a sound is produced. When the students hum, there is a vibration; when there is no sound, there is no vibration. For sound waves to be produced, the material has to vibrate.
Example Question #8 : Investigate How Vibrating Material Makes Sound
Students are told to make sounds in class. They stomp their feet, whistle, clap, and snap their fingers.
What do all these sounds have in common?
The students are still before or during the sound.
The students are having fun making the sounds.
Something is moving before or during the sound.
Something is moving before or during the sound.
All of these sounds have movement in common. Something is moving before or during the sound so cause it to happen. Vibrations from clapping or whistling create the sound waves that carry the noise we hear to our ears.
Example Question #9 : Investigate How Vibrating Material Makes Sound
Place a ruler on the edge of a desk, so that eight inches of it hangs over the side. Place one hand on the four inches that remain on the desk to hold the ruler securely. With your other hand, whack the end of the ruler that is hanging off of the desk. The ruler will vibrate up and down.
What will be produced because of the vibrations?
Strong winds will be produced.
A sound will be produced.
Nothing will be produced.
A sound will be produced.
Sounds will be produced because of the vibrations from the ruler. When the ruler is whacked and vibrates up and down, sound waves are created, and noise will be heard.
Example Question #10 : Investigate How Vibrating Material Makes Sound
What is the definition of sound?
What you see when your eyes focus on a picture or image
What you hear when vibrations happen and sound waves travel to your ear
What you taste when you eat something sweet or sour
What you hear when vibrations happen and sound waves travel to your ear
Sound is what you hear when vibrations create sound waves and they travel to your ear to be processed. When vibrations happen sound is created.
