While playing in the park, Isla, Kai, and Avery hear a loud, low-pitched rumble in the distance. Which of these statements about the noise is NOT true?

• The vibrating object is traveling through the air.

• The object is vibrating slowly to produce the low pitch.

• Sound waves are traveling through the air to Isla, Kai, and Avery's ears.

• The sound is being produced by the vibration of an object.

Imagine Scarlett and Liam are playing a game of catch in the schoolyard. Scarlett throws a ball at a concrete wall and then at a carpeted wall with the same force. Why does the ball make a louder sound when hitting the concrete wall compared to the carpeted wall?

• The carpeted wall absorbs the sound.

• The concrete wall doesn't move.

• The vibrations of the concrete wall need more energy.

• The vibrations of the carpeted wall will absorb less energy.

Michael is curious why water pouring into a bathtub makes a sound. Can you help him figure it out?

• The moving water is a source of sound.

• The moving water converts sound energy to motion.

• The moving water allows sound to fill the empty space it leaves.

• The moving water causes vibrations in the air.

Imagine Grace is in her music class and excitedly plucks a string on her guitar. What is the most likely reason a sound is produced?

• The guitar string gets louder.

• The guitar string makes an echo.

• The guitar string vibrates.

• The guitar string has a higher pitch.

Imagine Daniel and Ava are trying to chat using two cans connected by a string, as shown in the picture. How does their message get across?

• By using heat energy from their breath to send heat energy down the string

• By causing vibrations with their voice to send sound energy down the string

• By using the light energy in the air to send sound energy down the string

• By shaking the cans to make magnetism, which travels down the string
