Dionne and Zoe are partners in science class. They have been asked to design a device that will communicate sound across a distance. Dionne thinks their device would work best if they used some kind of solid object to transfer the sound across a distance. Zoe, on the other hand, thinks their device would work better if it used the air to transfer the sound. Who is correct? Why?

• Zoe because sound vibrations travel best through the particles in air

• Dionne because sound vibrations cannot travel through the particles in air

• Zoe because sound vibrations cannot travel through the particles in solids

• Dionne because sound vibrations travel best through the particles in solids

Chloe is designing a device to communicate across a distance by using sound. She is doing some research before she decides on her design plan. She looks at a magnified diagram of the particles in a solid, liquid, and gas, as shown. Chloe needs her device to communicate sound quickly. Using the diagram, what information will help Chloe create the fastest communication device?

• Chloe needs her device to communicate sound quickly. Using the diagram, what information will help Chloe create the fastest communication device?

• Sound waves always travel at the same speed in a solid and a liquid.

• Sound waves travel the fastest in a gas because the particles are the farthest apart.

• Sound waves travel the fastest in a solid because the particles are the closest together.

Which animal makes a sound that has a high pitch?

• bird

• lion

• elephant

• alligator

Which of these sounds are soft?

• whisper

• fire truck

• motorcycle

• sneeze

Adelyn is designing a device that will communicate simple messages using sound waves. She fills four glass bottles with different amounts of water. The picture shows part of her device. She will tap different bottles with a spoon to create sound waves to send different messages. Why does Adelyn put different amounts of water in each bottle?

• She will be able to create different pitches of sound.

• She will be able to create different speeds of sound.

• She will be able to create different lengths of sound.

• She will be able to create different volumes of sound.
