i learned that waves could be strong and could transfer energy.

# data[].attributes.body
I learned that waves can move things up and down like the little balls in the video.

# data[].attributes.body
I learned that sound waves go through the air and in the auto space their is no sound waves.

# data[].attributes.body
I learned that without air, sound waves are not able to travel.

# data[].attributes.body
I learned that talk throw something it makes waves .

# data[].attributes.body
I learned that sound waves do not travel in space. Waves are a pattern of motion that transfer energy.

# data[].attributes.body
I learned that talt throw something it makes waves

# data[].attributes.body
I learned is that when you hear music there are waves in the air.

# data[].attributes.body
I learned that matters doesn't move through waves only energy does.

# data[].attributes.body
I learned that the shorter the wavelength has the more energy the wavelength has.

# data[].attributes.body
I learned that wavelength is shorter then it has more energy.

# data[].attributes.body
I learned that you can make waves when you are in a football game.

# data[].attributes.body
I learned that more energe to the water it moves big waves and wen you do it ligth only small waves move .

# data[].attributes.body
I learned that when a wave goes up and down we call it a transverse wave.

# data[].attributes.body
I learned that if you amplitude makes the waves smaller.

# data[].attributes.headline
i learned that if u take the air out of a phone u cant here and waves they move different ways

# data[].attributes.subject
i learned that if u take the air out of a phone u cant here and waves they move different ways

# data[].attributes.body
I learned when they start it the ball went up and down and the water went back and forward.

# data[].attributes.body
I learned that wavelengths are the distance between peak to peak of a wave. Amplitude is how tall or short a wave is and is the distance from the peak to the resting point.

# data[].attributes.body
I learned that amplitude is the distance from the waves pick to its resting point witch is the level of calm water.

# data[].attributes.body
I learned that transverse wave is when the disturbance moves perpendicular to direction of the wave.

# data[].attributes.body
I learned that sound waves are different than water waves and sound waves can travel in all directions.

# data[].attributes.body
I learned that when wave move up and down there call transverse waves.

# data[].attributes.body
What I learn is that sound is cause by vibration and flotes through the air without the air we can't hear the sound waves.

# data[].attributes.body
I learned that when a speaker vibrates it causes air particles to vibrates in the form of a longitudinal wave

# data[].attributes.body
I learned that longitudinal wave is when the disturbance moves parallel to the direction of the wave.That's what I learned today.

# data[].attributes.body
I learned that sound waves do not travel in space.

# data[].attributes.body
I learner that sound waves have vibrations.

# data[].attributes.body
I learned that waves are everywhere.

# data[].attributes.headline
i learned that exploshins in space dont make a singo sound.

# data[].attributes.subject
i learned that exploshins in space dont make a singo sound.

# data[].attributes.body
What I learn is that there's airparticals with out them we can't her music.

# data[].attributes.body
I learn that dolphins make sounds that travel under water.

# data[].attributes.body
I learned that sounds can travel through anything.

# data[].attributes.body
I learned that eathequekes are sound waves that can be strong.

# data[].attributes.body
I learned that dolphins can do vibration under water and that is how they comunucat .

# data[].attributes.body
i learned that you could do waves with anything

# data[].attributes.body
I learned that without air particles they will be nothing to vibrate.

# data[].attributes.body
I learned that without air particles they will be nothing to vibrate.

# data[].attributes.body
I learned today is that sound waves travel in all directions also we could here from long places.That's what I learned today.

# data[].attributes.body
I learned that waves are like echolocation or a Earthquakes.

# data[].attributes.body
perecos in the air.

# data[].attributes.body
What I learn is that there is particals in the air that makes sound waves.

# data[].attributes.body
I learned is that when they put the phone in side of the vacuum chamber they suck out the air we could not hear the music.

# data[].attributes.body
i learned that if you take out air out of something is will faint away so you will not hear it.

# data[].attributes.body
I learned that if the pumper removes all the air then the sound waves have nothing to travel through.

# data[].attributes.body
I learned that without air there is no sound.

# data[].attributes.body
I learned that when a wave moves up and down Its called transverse i kinda learned the same thing as Jeriel.

# data[].attributes.body
I learned today is that when Izzy turn on the vacuum will suck up the air then there are no sound if Dr. Jeff turn off then we could hear the sound again.That's what I learned to day

# data[].attributes.body
I learned that no air there no sound.

# data[].attributes.body
I learned that you can make your own wave motel made out of gummy bears.

# data[].attributes.body
I learned that in the real world,dolphins make sounds that travel like underwater waves for navigation.

# data[].attributes.body
I learned that without air there is no sound, there is no sound is space.

# data[].attributes.body
I learned that amplitude is the distance from the waves pick to its resting point witch is the level of calm water

# data[].attributes.body
I learned that waves are everywhere.

# data[].attributes.body
I learned that in real world dolphins make sounds that travel like underwater waves for nagvigation.

# data[].attributes.body
I learned that without air there is no sound there is no sound in space
