Parts of a sound wave
What does it mean?
Random
Sound traveling
100
What are the highest and lowest points of a sound wave called? And draw it.
crest and trough
100
What does high frequency mean?
High pitch!
100
How does sound happen? What is happening to the molecules?
Vibrations!
100
Does sound travel fastest in the ocean, a desk, or a can of paint?
A desk
200
What is the height of the wave called? And draw it.
Amplitude
200
What does low frequency mean?
Low pitch!
200
Does sound move faster is solid, liquid, or gas?
Solid
200
Put these in order from fastest to slowest based on speed of sound:
1. A lake
2. A slab of concrete
3. A balloon filled with air
fastest = concrete
middle = lake
slowest = balloon filled with air
300
Draw a high frequency wave
Drawing:
300
If a sound wave has a TALL amplitude, what does this mean?
The sound is loud.
300
Why does sound travel FASTEST in solids?
Because the molecules are packed tightly and create more vibrations!
300
How does SONAR use sound to locate object?
Using sound waves that bounce off/reflect off of objects!
400
Draw a low frequency wave
Draw it:
400
If a sound wave has a LOW amplitude, what does that mean?
Soft sound
400
Which sound is the SOFTEST?
Leaves rustling
400
What energy transformations does playing a guitar go through?
Mechanical -> Sound
500
How do you measure the distance between one wave and another? Draw it
Using wavelength
500
When a sound wave has a part that is VERY close together, what is it called? 
Compression Wave
500
What is echolocation?
Echolocation is a technique used by bats, dolphins and other animals to determine the location of objects using sound!
500
When an opera singer uses her voice to break a glass, what is happening to the glass? What makes it break?
The vibrations and/or high pitch!
