AMPLITUDE
Amplitude is related to...
Volume!
Frequency is related to...
Pitch!
What are soundwaves?
A group of particles colliding into each other
What are the three components of a CER?
Claim, Evidence, Reason
What part of your ear does sound bounce off of?
The Eardrum
On a graph, how do I know that a sound has a HIGH amplitude?
If there is a high distance from the peak to the resting point.
A sound with high frequency has a high ________
Pitch!
How do you draw a model of a soundwave?
Draw small circles colliding into each other to model particle collisions
What is the purpose of a claim?
To state what you think/ to answer the question
This is the part of the ear that vibrations hit first
How do I measure AMPLITUDE on a graph?
You measure how far the peak is from the resting point.
How do I measure FREQUENCY on a graph?
I count how many peaks are in the graph.
A soundwave that has more than energy has more...
More Amplitude! /It is louder/ Higher Volume
What is the purpose of evidence?
To use specific information to support our claim.
This is the part of ear that gets damaged when it hears loud sounds
Which graph in this drawing has a higher amplitude? Why?
Graph A
Whose voice has a higher pitch? Ms. Rutty or Mr. G? Explain
Ms. Rutty. Mr. G has a lower voice
How do soundwaves cause something to move?
What is the purpose of your reasoning?
The reasoning ties the evidence and claim together. It describes what the evidence shows.
Which sounds are more damaging for you ear? Loud sounds or high-pitch sounds?
Loud sounds because they transfer more energy than high pitch sounds
What is the amplitude of this graph A?
5
What is the relationship between frequency and vibrations?
Something that has a higher frequency has faster vibrations, something that has a lower frequency has slower vibrations.
Soundwaves travel from ______________ to ______________.
Soundwaves travel from sound source to sound receiver.
What makes for a strong CER?
Having strong pieces of evidence and being clear in our reasoning as to why our evidence supports our claim.
Why are loud sounds more damaging to our ears than high pitch sounds?
There is more energy in high amplitude sounds. More energy transfers into our ear damaging the stereocilia.
