I HAVE....through a medium composed of matter(solid, liquid or gas)
WHO HAS....Why does sound not travel through a vacuum?
I HAVE....a vacuum does not contain any matter
WHO HAS.... Which state of matter does sound pass through the easiest?
I HAVE....more easily through solids than through liquids or gases
WHO HAS....Why does sound travel easier and quicker through a solid?
I HAVE....the molecules of a solid are closer together
WHO HAS.....How do sound vibrations travel?
I HAVE.... In waves
WHO HAS....What is a wave?
I HAVE....A disturbance moving through a medium (solid, liquid, gas)
WHO HAS....What is the high point of a wave called?
I HAVE.... the crest
WHO HAS....What is the low point of a wave called?
I HAVE..... the trough
WHO HAS....What is the distance like in a short wave?
I HAVE....there is not much distance between its crest and its trough
WHO HAS....What is the distance like in a long wave?
I HAVE....there is a lot of distance between its crest and its trough
WHO HAS....How do you measure a wave?
I HAVE....by measuring the distance between one crest and the next crest of a wave
WHO HAS....The definition for frequency when pertaining to sound?
I HAVE....the number of waves in a given unit of time, such as a second
WHO HAS.....What is the unit of measurement for frequency of sound?
I HAVE.....Hertz
WHO HAS....The definition of pitch?
I HAVE....the highness or lowness of a sound, determined by the frequency of a vibrating object
WHO HAS....What happens to pitch when frequency is higher?
I HAVE..... the pitch is "higher" or "shriller"
WHO HAS....When is sound amplified?
I HAVE....when sound resonates
WHO HAS....List three communication devices that produce a form of sound.
I HAVE....Morse code, radar, sonar
WHO HAS....What is Morse code?
I HAVE.... a system used for sending messages
WHO HAS....What is radar?
I HAVE....an electronic instrument used to detect and locate moving or fixed objects in air or space
WHO HAS....What is sonar?
I HAVE....a device that sends sound waves through the air or water and locates objects as the waves bounce back
WHO HAS....How do musical instruments use sound?
I HAVE....these instruments use vibrating columns of air or vibrating strings to produce beautiful sounds
WHO HAS....Which animals hear and produce frequencies of sound different from those heard or produced by humans?
I HAVE....dogs, cats, dolphins, bats
WHO HAS....How do dogs, cats, dolphins, and bats use these different frequencies of sound?
I HAVE....to communicate with or detect one another
WHO HAS....Do objects that vibrate faster have a high pitch or a low pitch?
I HAVE.... high pitch
WHO HAS....Do objects that vibrate slower have a high pitch or a low pitch?
I HAVE....low pitch
WHO HAS....The definition for vibration?
I HAVE....the back and forth movements of matter
WHO HAS....What is the frequency like in a high sound?
I HAVE....has high frequency, many waves are produced each second
WHO HAS....What is the frequency like in a low sound?
I HAVE....has low frequency, fewer waves are produced each second
WHO HAS....Why does sound travel slower through a gas?
I HAVE....molecules of a gas are farthest apart
WHO HAS....The definition for wavelength?
I HAVE....the distance between one crest of a wave and the next crest.
WHO HAS....The definition for amplitude?
I HAVE....the measure of the amount of energy in a sound wave
WHO HAS....What is the amplitude like with a loud sound?
I HAVE....a loud sound is represented by a sound wave with a large amplitude
WHO HAS....What is the amplitude like with a soft sound?
I HAVE....a soft sound is represented by a sound wave with a small amplitude
WHO HAS....What is the speed of sound?
I HAVE....346 meters per second or 1,125 feet per second in air
WHO HAS....What affects the speed of sound?
I HAVE....the material through which it moves, and the temperature of the material through with it moves
WHO HAS....Does sound travel faster or slower when the temperature is colder?
I HAVE.....sound travels slower
WHO HAS....Does sound travel faster or slower when the temperature is warmer?
I HAVE....sound travels faster
WHO HAS....Can sound travel through a vacuum such as space?
I HAVE....no, sound waves require matter to travel through
WHO HAS....The definition for volume of sound?
I HAVE....how loud or soft a sound is
WHO HAS....The definition for decibel?
I HAVE....the unit used to measure sound intensity or volume
WHO HAS....The definition for a vacuum?
I HAVE....a space that is empty of any matter
WHO HAS....What happens to a sound wave as it travels away from the object that made the sound?
I HAVE....the wave and the sound gets weaker
WHO HAS....What is echolocation?
I HAVE....a process of locating objects by using sound waves
WHO HAS....What is sound?

(1st card)
I HAVE....a form of energy that is produced by vibrations of an object, and travels through matter as waves.
WHO HAS....What can sound travel through?
