Sound Vocabulary Lesson 1

Sound Vocabulary Lesson

What is sound?

• ​Well, I know it is the opposite of quiet.

• ​Does it have anything to do with noise?

• ​I know my teacher says they don't want to hear a sound...

Poll

What is sound?

• to move quickly back and forth

• energy created by waves from vibrations of matter

• annoying country music

• a very bright light that shines through a prism

​Sound

​energy created by waves from vibrations of matter, how high or low a sound is (the greater the frequency - vibrations per second - the higher the pitch)

​Vibrations

• ​Do you have good vibrations?

• When you vibe well with someone it means that you are both creating similar emotion/thought vibrations

• Now let's think about science.

• What does vibration mean in science?​

Poll

What does vibrations mean?

• perfect stillness

• all the good energy

• the act of moving quickly back and forth

• the strength or loudness of a sound wave

​Vibrations are...

the act of moving quickly back and forth

​Absorb

• What happens when a sponge soaks everything up?

• ​Do you soak up all the knowledge I give you?

• ​What happens when you go out in a ​torrential downpour?

• ​Yep.

• ​Soaked.

• ​Did you absorb it?

Poll

Which one defines absorb?

• take in

• to shine light on

• what sound travels through

• Area with no matter

​absorb

​take in

​that's it - this is a simple one!

​Transmit

• ​Hmmm... This makes me think of E.T. when he was trying to phone home. He needed to transmit a signal. ​

Poll

What does transmit mean?

• take in

• to transform into another thing

• make it all the way

• go through

​So, transmit means...

​go through

​

​E.T. wanted his signal to go through to his home.

​Volume.

​Here are some definitions of volume:

• ​a book forming part of a work or series

• ​the amount of space that a substance or object occupies

​

Those aren't what we need!!

​This isn't reading or math, it is SCIENCE!!

Poll

Define volume (for our unit of SOUND in science).

• the strength or loudness of a sound wave -- measured in decibels

• a book forming part of a work or series

• the amount of space that a substance or object occupies

• what sound travels through

​Volume:

​

​the strength or loudness of a sound wave -- measured in decibels

How we hear amplitude! How loud or soft a sound is.

​What is a sound wave?

• ​How do sounds get to us?

• ​What do you think?

Poll

What is a sound wave?

• when you yell loudly while waving to your friend

• the loud crashing waves at the beach

• to move quickly back and forth

• Energy from a vibration that travels in series of compressions (like waves)

​Sound Wave

​Energy from a vibration that travels in series of compressions (like waves)

​What do you think of with the term medium?

• That's what size I wear!

• Something that is in a middle position?

• ​Someone who can speak to the dead​?

​

Nope! This is another definition!​

Poll

Which one do you think is the definition for medium?

• what sound travels through (solid, liquid or gas)

• not too big, not too small

• how high or low a sound is

• to move quickly back and forth

What is a vacuum?

• ​Not the thing to clean the floor

• ​Not the brother who eats all the food at dinner

• But, it does have something to do with being empty

​

​Think about what vacuums do, and what the brother does when he eats all the food. The vacuums take all the dirt and things out of the carpet. And the brother devours everything, leaving nothing.

Poll

Which one defines vacuum for our sound unit?

• area with no matter (sound cannot travel through)

• area with lots of particles in the air

• how high or low a sound is

• what sound travels through

​vacuum

​area with no matter (sound cannot travel through)

​pitch

• ​Not when the pitcher throws the ball

• ​Not like the pitch of a roof

• ​Not like the pitch that is the turf on a football field.

​

​This one is has to do with sound. Did you ever talk about pitch in music c​lass?

Poll

Which one defines pitch, as we use it in our sound unit?

• when you throw the ball right into the strike zone

• the strength or loudness of a sound wave -- measured in decibels

• Energy from a vibration that travels in series of compressions (like waves)

• how high or low a sound is (the greater the frequency - vibrations per second - the higher the pitch)
