Imagine Bailee and D'Mya are in a science museum, standing in front of a fascinating exhibit about sound. D'Mya turns to Bailee and asks, 'What are vibrations?'

• Vibrations are static energy being absorbed.

• Vibrations are how loud or soft a sound is

• Vibrations are caused by pitch.

• Vibrations are caused by something moving back-and-forth quickly.

Hasset, Alana, and Matthew are curious about sounds. They're wondering, what exactly is pitch when we talk about sound?

• Pitch is the duration of a sound wave.

• Pitch is the volume of a sound wave.

• Pitch is the timbre of a sound wave.

• Pitch in relation to sound is the perceived frequency of a sound wave.

Imagine Cornelius is at a concert, feeling the music vibrate through him. What is he experiencing in terms of sound?

• Volume is the taste of sound, like the flavor of her favorite song.

• Volume is the temperature of sound, warming her up with every beat.

• Volume is the color of sound, painting the air with melodies.

• Volume is the loudness or intensity of sound, filling her with energy.

Imagine Aria and Yusef are at a concert. Aria thinks the music is too loud, but Yusef believes it's just perfect. Explain how volume and amplitude are related in sound to settle their debate.

• Amplitude has no effect on sound volume.

• Volume and amplitude are completely unrelated.

• Higher volume results in a softer sound.

• Higher amplitude results in a louder sound.

Imagine Jayceon, Quentavius, and Kristopher are in a band. Jayceon is on the guitar, Quentavius rocks the drums, and Kristopher is all about that bass. If Kristopher wants to make the pitch of his bass guitar higher, what should he do with the frequency of the sound waves?

• Higher frequency produces lower pitch

• Frequency has no effect on pitch

• Higher frequency produces higher pitch

• Frequency affects the volume, not the pitch

Imagine Randon, Cooper, and Evelyn are at a rock concert, feeling the music vibrate through them. This makes them wonder, what role does the ear drum play in hearing these awesome tunes?

• It amplifies sound waves

• It converts sound waves into electrical signals

• It reflects sound waves out of the ear

• It vibrates in response to sound waves
