What is the highness or lowness of a sound?
What is pitch?

What is it called when an animal like a bat or dolphin and humans can bounce sound off of their surroundings to give them an idea of where they are located at?
What is echolocation?

What is it called when sound is reflected?
What is echo?

When the small harp string is plucked, it gives us a high pitch. When the large harp string is plucked, it gives us a low pitch. Pitch deals with how _______________________________________________.
What is how fast an object vibrates.

In a thunderstorm, you can tell which one is faster? Which is faster, light or sound?
What is light travels faster than sound?
200
What is the loudness or softness of a sound?
What is volume?
200
What must sound have in order sound to travel?
What is a medium like air, water, or glass?
200
How does sound move?
What is sound moves out in all directions like a pebble thrown into a pond?
200
In the bottles full with different water levels, which bottle gave us a low pitch and which bottle gave us a high pitch and why?
What is the bottle with no water or less water gave us a low pitch because sound had more room to vibrate and give us a low frequency wave. The bottle with the most water gave us a high pitch because sound had the least amount of room to vibrate resulting in a high frequency wave.

What happens to the molecules when we say compression?
What is the molecules squeeze close together?
300
What happens to the sound in the gym with wood floors? Why?
What is the sound will reflect and fill up the large area because hard objects bounce the sound off.
300
Why does sound not travel in space?
What is there is no air (no medium) in space for sound to move through?

Explain 2 things the object must be like in order for it to have a lower pitch? think about a string instrument
What is the object must have thicker strings, longer strings, and wider.

In the telephone experiment, what happened when the person didn't have the string tight - rather the string was loose?
What is the vibrations can't move down the string and communication can't be made between the two people.
300
High frequency - gives us more or less vibrations? Low frequency - gives us more or less vibrations?
What is high frequency gives you more vibrations? What is low frequency gives you less vibrations?
400
Why in a theater do they have soft sponge like and foam like pads along the wall? How does this affect sound?
What is the soft materials like foam pads will absorb sound and make it so others in another theater won't hear it?

When doctors use sound and reflect the sound off the baby inside the mother's belly we call this ______________.
What is an ultrasound?
400
Explain what a higher pitch string instrument would be like to give it a higher pitch.
What is shorter strings, thinner strings, and smaller in size?
400
In the nail lab, what nail had the highest pitch and why?
What is the shortest nail because sound had less room to vibrate resulting in a high frequency wave?
400
Explain to me how sound will travel in a solid, liquid, and gas. Which one is the slowest? Which one moves at a medium speed? and Which one is the fastest for sound to move?
What is sound moves fastest in a solid because the molecules are close together, sound moves the medium speed through liquids because particles are alittle more spread out, and in gas, sound moves the slowest because the particles/ molecules are much more spread out.

Volume is measured in _____________. Frequency is measured in _______________.
What is decibels? What is hertz? Alot of waves with hurts you!!!
500
Why can humans not hear a dog whistle?
What is humans can't hear it because it is out of their hearing range?

In class, Mr. Rethman showed you how sound moves and can bunch up in certain areas as it moves down the slinky. What do we call sound waves? Think about the slinky being long.
What is a longitudinal and compression wave?

Mr Coons is strumming two strings on the guitar. The first string vibrates more quickly than the second string. What sound will the first string have compared to the sound of the second string? Why?
What is the first string will have a higher pitch because it vibrates faster and the second string will have a lower pitch because it vibrates slowly.
