100
Name two animals that can hear on a higher frequency than humans.
dogs, cats, bats, and robins (to name a few)
100
What is the top of a wave called? What is the bottom of a wave called?
top-peak (or crest) bottom-trough
100
A form of energy that travels in waves and is produced and transmitted by vibrating matter is ___________.
sound
100
Give an example of a sound with high pitch.
(Listen to sound)
100
True or False. Sound travels faster than light.
False. Light travels much faster than sound.
200
Draw a diagram to show the direction that sound waves travel.
The diagram should show sound waves traveling in every direction.
200
What type of matter do sound waves travel best through? Why?
Sound waves travel best through dense solids because the molecules are close together.
200
_____________ determines how loud or soft a sound is.
Volume
200
Give an example of a sound with high pitch and low volume.
(Listen to sound)
200
Give two reasons sound is useful.
Communication, locating food, sonar, and entertainment
300
_____________ is created by vibrations.
Sound
300
Draw a wave with high pitch and low amplitude.
There should be a lot of waves close together and short.
300
What is wavelength?
The distance between a point on one wave to the same point on the next wave.
300
Give an example of a sound with low pitch and high volume.
(Listen to sound)
300
How is an echo created?
An echo is created when sound waves bounce off of something.
400
DOUBLE JEOPARDY!!! True or False. If there was a loud explosion in space we would not hear it.
True. There is no matter in space, so the sound waves would not have anything to bounce off of.
400
Draw a sound wave that has low pitch and high amplitude.
The waves should be very spread out and tall.
400
What is echolocation and give an example of who uses it.
The use of sonar by animals to find places and food. Bats and whales are two examples of animals that use echolocation.
400
Give an example of a sound with low frequency and high amplitude.
Sound should be low pitch and loud.
400
DOUBLE JEOPARDY!!! A/an __________ is a material that carries sound waves and a/an _________ does not carry sound waves.
A medium is a material that carries sound waves and an insulator does not carry sound waves.
500
If a tree falls in the forest and no one is there to hear it, does it really make a sound?
Yes. The sound waves would be able to travel through the air, the solid ground, any other trees or plants, and water if there is a stream or lake close by.
500
Draw a sound wave with high frequency and high volume.
There should be a lot of tall waves close together.
500
What is sonar? Who uses it?
Using sound waves to detect and locate objects, especially underwater. It is used by people.
500
Explain which words are related: pitch, volume, amplitude, frequency.
A sound with high frequency has a high pitch. A sound with low frequency has a low pitch. A sound with high amplitude has a high volume. A sound with low amplitude has a low volume.
500
Music is ___________ sound and noise is _____________ sound.
Music is organized sound and noise is unorganized sound.
