High pitch
Loud volume
Sound travels in _________?
Vibrations
Tyrone plucks two strings of a violin. The first string makes a low pitch, but the second string makes a high pitch. What does this tell you?
The first string is thick, and the second string is thinner.
Diamond taps a small tuning fork on her desk, and then she strikes (hits hard) the same tuning fork on her desk. Which action will produce more vibrations?
Striking the tuning fork
A thick rubber band
Someone typing on their keyboard
Soft volume
Sound travels best through which state of matter?
Legacy plays the guitar in music class. What should she do to change the pitch of the guitar?

What is an insulator? Give an example.
An object that blocks the passage of sound energy.
Ex: Headphones.
Fast/frequent vibrations
What is the amplitude of vibrations in a soft volume.
Weak vibrations
Scientists have proven that sound travels through vibrations in the air. Give an example of how sound produces vibrations. (Think back to some of our experiments!)
Explain TWO ways to change an object's volume.
- Insulators
Explain the process of sound energy using a record player as an example.
The needle and grooves of the record collide to create mechanical energy. The needle and grooves create vibrations, which creates sound energy.
