Ear
This part, the outside of the ear, takes a different shape in each animal and is especially large in elephants.
What is the Pinna?
All sound sources must do this in order to make a sound
What is Vibrate?
In a graph, frequency is shown with this
What is number of compression bands
Sound travels slowest through this medium
What is air?
Graph A has two short peaks. Graph B has 7 tall peaks. What can you say about these two graphs as it relates to pitch and loudness.
What is graph A is shorter and quieter?
This part of the ear has three little bones and amplifies (makes louder) the sound
What is the Ossicles?
This is how thick/thin/tall/short a wave is
What is Amplitude?
In a graph, amplitude is shown with this.
What is width/size of compression bands.
A man screams across the room to his student. This is what happens in between the student and the man.
What is particles bump into each other transferring energy?
Object A is vibrating faster than object B. What must be true about object A?
Object A has higher frequency/pitch
How does a sound wave interact with an ear?
What is it vibrates against the eardrum?
This is the space in between compression bands
What is a rarefaction?
This is the distance between two compressions/waves
What is wavelength?
The fastest way to get a sound to travel is through which of these materials: Air, Water, Ketchup, Steel
What is steel?
The same sound is traveling at 1 foot, 1,000 feet, and 10,000 feet off the ground. Which sound travels the fastest and for what reason?
What is the 1 foot sound because particles are more densely packed?
This part of the ear has a bunch of little hairs inside and process the pitch of a sound
All sound must travel through this
What is a medium?
Imagine a waves graph. If you increased the pitch what would be the effect on the graph
What is more bands?
This is the reasoning for why sound travels fastest through a solid
What is the particles are packed closely together so the energy transfers quickest?
An orchestra conductor asks piano player to hit the keys harder. With science words, explain what the conductor wants to hear.
What is greater amplitude/loudness?
What is nerves/auditory nerve?
Sound can not travel in this because lack of particles
What is a vacuum?
When a group of waves has the same number of bumps what does that mean?
They have the same frequency/pitch
This is the reasoning for why sound travels slowest through gas.
What is Gas particles are further apart so it takes longest for them to transfer?
DAILY DOUBLE!!!
See the three waves being drawn on the board. What are similar and what are different about the waves?
As Drawn (probably same frequency different Amplitude)
