Sounds Through Solids, Liquids, Together

Hey there, science whizzes! Evi, Raegan, Abbey, and Rachel are having a heated debate. They're trying to figure out through which type of medium do sound waves zip through the fastest: is it solids, liquids, or gases? Can you help them settle this once and for all?

• liquids

• plasmas

• solids

• vacuums

Imagine Cash, Lucas, Nickali, and Bryce are on a construction site, standing next to a giant concrete pillar. Cash taps the pillar and the sound travels to Bryce. How does this happen?

• Particles in the solid vibrate and pass the sound energy along to Bryce.

• Sound waves travel in a straight line through the pillar to Bryce.

• Sound waves do not travel through solids, so Bryce hears nothing.

• Sound waves travel faster in solids, making the sound reach Bryce instantly.

Imagine Gavin, Lucas, Alan, and Jasper are scientists with the power to control sound. They're on a mission to study the effects of sound waves, and they need to send a secret sound signal from a solid metal door to a liquid lava pit. What happens to the speed of their sound signal when it travels from the solid metal door to the liquid lava pit?

• The speed of sound increases

• The speed of sound decreases

• The speed of sound remains the same

• The speed of sound becomes silent

Imagine Da'meer, Jackson, and Jace are deep-sea explorers who collect samples. Which option will have the HIGHEST pitch?

• a bottle 1/2 full

• a bottle 1/4 full

• a bottle 3/4 full

• a bottle completely full

Imagine Kaila, Delaney, and Brynn are in a science museum, standing in front of a fascinating exhibit about sound. The exhibit challenges them with a question: What is the primary factor that affects the speed of sound in a medium?

• Pressure

• Volume

• Density

• amplitude

Imagine Cole, Jonathan, and Blake are astronauts on a space mission. They start a debate: Can sound waves travel through the vacuum of space? What do you think?

• Yes

• Only in space

• Sometimes

• No

Imagine Derrick and Gabe are in a music hall, testing an acoustic device. They notice something interesting when they move the device from the carpeted area to the wooden stage. What is this phenomenon called, where sound waves change direction as they pass from one medium to another?

• Diffraction

• Refraction

• Reflection

• Absorption

Imagine Cayden, Amira, Kolton, and Cason are in a science museum, standing in front of a fascinating exhibit about sound. Cayden wonders aloud, 'How does the density of a medium affect the speed of sound?'

• The speed of sound is not affected by the density of the medium.

• The speed of sound remains constant regardless of the density of the medium.

• The speed of sound increases as the density of the medium increases.

• The speed of sound decreases as the density of the medium increases.

Hey there, speedsters! Erina, Lakyn, Isabella, and Braylie are curious about how fast sound can zoom through the air. Can you help them figure out the unit used to measure the speed of sound in a medium?

• mph

• km/h

• m/s

• ft/s

Imagine Joshua, Eli, and Logan are in a band. They noticed that their music travels faster through their wooden stage than through the air. Why do you think that is?

• Particles in solids are closer together than in gases.

• Gases have a higher molecular weight than solids.

• Sound waves in solids are weaker than in gases.

• Solids have less dense particles compared to gases.
