Hudson plucks two strings of a violin. The first string makes a low pitch, but the second makes a high pitch. What does this tell you?
The first string is producing faster vibrations
The second string is producing faster vibrations
The two strings are vibrating at the same speed
Someone with a deep voice produces...
A high pitch
A low pitch
A small tuning fork produces
A high pitch
A low pitch
A large tuning fork produces
A high pitch
A low pitch
Your teacher has a LOUD voice. This means their voice
Produces larger vibrations
Produces smaller vibrations
Produces the same amount of vibrations as a person with a soft voice.
Produces no vibrations
What does this table tell us about how sound travels
Sound travels at the same speed
Sound travels fastest through solids
Sound travels fastest through liquids
Sound travels fastest through gasses
Michael Taps a small tuning fork on her desk, and then she strikes the same tuning fork on her desk. Which will produce more vibrations
Tapping
Striking
What is the BEST conclusion Angelina could make from her experiments with violin strings?
The thinner the string the higher the pitch
The thicker the string the higher the pitch
The 5cm string make the lowest sound.
The thickness of a string does not affect the pitch.
Mary wants to figure out how to make the loudest sound at a basketball game. She experiments to see how force affects how loud her sound is. She measure the volume of the sound using decibels. Based on the chart, predict how loud kicking the seat will be in decibels.
5 decibels
15 decibels
45 decibels
100 decibels
Anthony's class has a short tuning fork, a medium tuning fork, and a long tuning fork. Their teacher tells them to strike the tuning fork and place the fork in a bowl of water. They oversee the pitch created and measure the vibrations of the tuning fork in Hertz.
What conclusion can Anthony's class make about how vibrations affect sound?
The size of the tuning fork affects the volume of a sound.
Higher pitches produce more vibrations
Lower pitches produce more vibrations
Larger objects produce more vibrations
Which answers are an example of sound producing vibrations?
Hitting the tuning fork
Plucking a rubber band
Ruler being held off of the desk and being hit
Tuning fork put in water after being hit
