• Reflection

Open Ended

Explain how whales benefit from the properties of sound travel in water.

Multiple Choice

Why does sound travel faster in water than in air?

• Because water is less dense than air

• Because particles in water are packed tighter, allowing energy transfer to happen more quickly

• Because water particles are larger than air particles

• Because sound waves are weaker in air

Multiple Select

Which of the following factors can increase the speed of sound in a medium?

• Higher temperature

• Lower elasticity

• Lower density

• Greater stiffness
