Front 7

I HAVE.....Hertz
WHO HAS....The definition of pitch?

Back 7

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?

Front 8

I HAVE..... the pitch is "higher" or "shriller"
WHO HAS....When is sound amplified?

Back 8

I HAVE....when sound resonates
WHO HAS....List three communication devices that produce a form of sound.

Front 9

I HAVE....Morse code, radar, sonar
WHO HAS....What is Morse code?

Back 9

I HAVE.... a system used for sending messages
WHO HAS....What is radar?

Front 10

I HAVE....an electronic instrument used to detect and locate moving or fixed objects in air or space
WHO HAS....What is sonar?

Back 10

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?

Front 11

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?

Back 11

I HAVE....dogs, cats, dolphins, bats
WHO HAS....How do dogs, cats, dolphins, and bats use these different frequencies of sound?

Front 12

I HAVE....to communicate with or detect one another
WHO HAS....Do objects that vibrate faster have a high pitch or a low pitch?

Back 12

I HAVE.... high pitch
WHO HAS....Do objects that vibrate slower have a high pitch or a low pitch?

Front 13

I HAVE....low pitch
WHO HAS....The definition for vibration?

Back 13

I HAVE....the back and forth movements of matter
WHO HAS....What is the frequency like in a high sound?

Front 14

I HAVE....has high frequency, many waves are produced each second
WHO HAS....What is the frequency like in a low sound?

Back 14

I HAVE....has low frequency, fewer waves are produced each second
WHO HAS....Why does sound travel slower through a gas?

Front 15

I HAVE....molecules of a gas are farthest apart
WHO HAS....The definition for wavelength?

Back 15

I HAVE....the distance between one crest of a wave and the next crest.
WHO HAS....The definition for amplitude?

Front 16

I HAVE....the measure of the amount of energy in a sound wave
WHO HAS....What is the amplitude like with a loud sound?

Back 16

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?

Front 17

I HAVE....a soft sound is represented by a sound wave with a small amplitude
WHO HAS....What is the speed of sound?

Back 17

I HAVE....346 meters per second or 1,125 feet per second in air
WHO HAS....What affects the speed of sound?

Front 18

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?

Back 18

I HAVE.....sound travels slower
WHO HAS....Does sound travel faster or slower when the temperature is warmer?

Front 19

I HAVE....sound travels faster
WHO HAS....Can sound travel through a vacuum such as space?

Back 19

I HAVE....no, sound waves require matter to travel through
WHO HAS....The definition for volume of sound?

Front 20

I HAVE....how loud or soft a sound is
WHO HAS....The definition for decibel?

Back 20

I HAVE....the unit used to measure sound intensity or volume
WHO HAS....The definition for a vacuum?

Front 21

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?

Back 21

I HAVE....the wave and the sound gets weaker
WHO HAS....What is echolocation?

Front 22

I HAVE....a process of locating objects by using sound waves
WHO HAS....What is sound?

(1st card)

Back 22

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?
