noise that travels through the air or another medium and can be heard when they reach a person's or animal's ear.
What is sound?

Imagine your teacher plays the high pitch sound of a bird singing. Draw a model of what that string should look like.
What is high pitched strings to look like this

Think about all the sounds and noises around you each day. Besides human voices, what are some other examples of things that create sound vibrations? Make a list.
What is a jackhammer, a truck driving by, stomping, clapping, drums beating?
200
motion of particles moving back and forth
what is vibration?

Imagine your teacher plays the low-pitched sound of a whale singing. Draw a model of what string should look like.
What is a low pitched string because the string would look more spaced apart.
200
Why can't sound vibrations travel in outer space?
What is because their is no air up there and sound needs to vibrate something in order to travel?
300
vibrating energy (molecules) that looks like a wave. They can travel through solids, liquids or gasses.
What is sound waves?

Isaiah has built a giant speaker so that he can play music really loudly. He has set the speaker right outside his neighbor’s house. Draw arrows and add words to the image below to show a model of what will happen to the glass window of the house when Isaiah starts playing music using the large speaker.

The pictures below show two different sounds, seen through an oscilloscope. One of them is the sound of a flute (a high-pitched sound), and the other is the sound of a tuba (a low-pitched sound). Which is the tuba? Which is the flute? How do you know?
Sound A Sound B
What is Sound A has longer waves compared to Sound B, which means it’s making a sound with a low pitch. Since a tuba has a low pitch, Sound A is the tuba. Sound B has shorter waves compared to Sound A, which means it’s making a sound with a high pitch. Since a flute has a high pitch, Sound B is the flute.
400
he measured distance between two identical points on two back-to-back waves
What is wavelength?

Mateo and Ava made a paper cup telephone that they use to communicate with one another. But
there is a problem: The string is too long, so there is a lot of distance between the two paper cups.
Mateo can hear sounds when Ava speaks, but he cannot hear the exact words. Mateo thinks that
they can solve the problem if they develop a code using a pattern of sounds. Generate at least
two different ideas that Ava and Mateo could use to communicate with a sound pattern when they
use the cups and string. Be sure to explain how each solution would work.
What is Solution 1 Morse code, where a pattern of short and long sounds are used to represent different letters or words. Solution 2 a code that uses sound pitches as a communication pattern.
500
sounds that are produced when an object vibrates rapidly
What is high pitch?

Mateo and Ava want to compare the solutions that you came up with to see which one will work better. Using the two solutions that you generated above, how could Ava and Mateo test these solutions to compare them and see which one works the best?
What is Ava sends a message using Solution 1 that instructs Mateo to sit down. Mateo hears the sound and sits down. Ava then sends a message using Solution 2 that instructs Mateo to stand on one foot. Mateo doesn’t stand on one foot. This is evidence that Solution 1 is better than Solution 2.
