Sound Energy
Sound is a form of what type of energy?
Mechanical
Sound travels fastest through _____ because the particles are _________.
solid; closer together
Mr. Nash is in the process of creating a water xylophone. He filled a glass cup half way and struck it with a spoon. He wants to add a new glass with a LOWER pitch. Should he put more or less water in the new glass?
What is an independent variable?
Sound is transmitted by what type of matter?
a. Vibrating
b. Soft
c. Loud
Vibrating
Sound travels slowest through _______, because the particles are ____________ apart.
gas;farther
Mr. Page created a homemade guitar by taking rubber bands of different widths and placing them around a box. When he struck the thickest band, he noticed the the pitch was LOWER than the rest. That is because the vibrations were (slower/faster)
slower
What is a constant?
It's a part of an experiment that stays the same between each trial.
Sound travels in __________ waves
compression
Would sound travel faster through steel or water? Why?
Steel. Sound travels faster through solids than liquids
True or False: The piano vibrates strings to form sound.
True
What is a hypothesis?
An educated guess as to what you think will happen in an experiment
Mrs. Pace placed a ringing alarm clock in a bell jar. She then used a vacuum pump to remove all the air particles from inside of the jar. Will she still be able to hear the alarm ringing? Why or why not?
No. She will not be able to hear the alarm because there are no air particles to transfer energy.
What type of particles vibrate as sound moves?
a. water
b. sound
c. air
air
Sounds with many vibrations per second have a _____ pitch.
high
What is a dependent variable?
The part of an experiment that is being tested.
Can you hear sound in space? Why or why not?
No. You cannot hear sound in space because space is a vacuum.
What are the 3 types of matter sound travels through?
Solid, liquid, and gas
The smaller the frequency the (higher/lower) the pitch
lower
Ms. Deel wanted to test if the amount of water in a glass affects the pitch made when struck with a spoon with the same amount of force. What is the independent variable in the experiment?
The amount of water added to the glass
