Travelling Sounds
100
What you get when you have vibration
What is sound?
100
The way you increase the volume of any sound
What is adding energy?
100
How high or low a sound is
What is pitch?
100
It separates the outer ear from the middle ear.
What is the eardrum?
100
To take in and hold sound (not letting the waves pass through)
What is absorb?
200
Something moving back and forth
What is vibration?
200
Units used to measure sound
What are decibels?
200
This determines whether a vibrating object makes a low-pitched or high-pitched sound
What is the speed (frequency) of the vibration?
200
It's the part of the ear that transfers sound waves to the nerve that goes to the brain.
What is the inner ear?
200
It's what happens to sound waves that are not absorbed by a material
What is reflection?
300
The way vibration feels on your skin
What is buzzing, tingling, or pins and needles?
300
A way to describe the peaks and valleys of a low volume (quiet) sound
What is short, shallow, or small?
300
This determines the speed of the vibration when a certain amount (the same amount) of energy is used to make an object vibrate
What is the size or mass of the object
300
It captures sound waves.
What is the outer ear?
300
Sound that is reflected
What is an echo?
400
The way you can change the sound of a vibrating rubber band or ruler
What is shortening or lengthening it?
400
Because they have more energy to start with and can go a greater distance before the waves flatten out
Why do loud sounds travel farther than soft sounds?
400
This explains how the pitch varied between the different water glasses
What is the fact that the vibration of the glass was slowed down by the water in the more full water glasses?
400
It transfers sound waves from the eardrum to the inner ear.
What is the middle ear.
400
This is a way to describe how sound travels through large amounts of water.
What is very well?
500
It's what makes an object vibrate and produces the waves that we experience as sound.
What is energy?
500
The outer ear collects sound waves to make sounds seem this way
What is louder?
500
This explains how the bike wheel and card produced a higher pitch.
What is the fact that as the speed of the wheel increased, the speed of the card's vibration increased?
500
The three tiny bones of the middle ear
What are the hammer, anvil, and stirrup?
500
It's the material (either a piece of wood or a handful of paper towels) that sound would travel better through and the reason why
What is paper towels, and because they are more porous?
