What’s That Sound?
Answer all questions using the READ method.
1.
What 3 things wake Max up from his sleep?
The 3 things that wake Max up from his sleep are the drilling, the pounding,
and his alarm clock
2.
Why can’t the worker hear Max’s neighbor, Al, talk? (Include a scientific
answer not just the object)
The worker can’t hear Max’s neighbor, Al, talk because he is wearing protective
ear wear. The earmuffs keep the sound wave from hitting the workers ears.
3.
What does Max say stronger vibrations cause?
Max says stronger vibrations cause more intensity and therefore greater
loudness/volume.
4.
Describe how the jackhammer makes sound waves.
As the jackhammer smashes the concrete, it produces vibrations that cause air
molecules to bounce off each other like ripples in waves. The transfer of
energy moves outward from the source
5.
What does frequency determine? What happens with a higher
frequency?
Frequency determines its pitch. The higher the frequency, the higher the
pitch.

Making Sense of the Waves
1. What do the folds and curves of the outer ear do?
The folds and curves of the outer ear collect sounds and funnel them to the
inner ear.
2. What is the job of the ear drum, the hammer, the anvil, and the stirrup?
The job of the ear drum, the hammer, the anvil, and the stirrup is to make the
sounds louder as they are sent into the inner ear.
3. What happens when the vibrations from the stirrup enter the cochlea?
When the vibrations from the stirrup enter the cochlea, the liquid in the
cochlea gets wavy and it begins to vibrate. Then the vibrations sent to the hair
cells cause the hair cells to send signals to the brain.
4. Why do sounds sound different underwater?
Sounds sound different underwater because sound travels 5 times faster
through water than air.
5. Why can’t you hear sounds in space without a radio?
You can’t hear sounds in space without a radio because space is a vacuum and
there is no material to travel through

What Sound Can Do
1. What happens to sounds when they hit a soft surface?
When sounds hit a soft surface they get absorbed.
2. What happens to sounds when they hit a hard surface?
When sounds hit a hard surface they bounce, or reflect back to our ears
creating an echo.
3. What happens to sound waves when they move from air to water?
When sound waves move from air to water the bend or refract.
4. What does SONAR stand for?
SONAR stands for SOund Navigation, and Ranging
5. What are 3 animals that use SONAR?
3 animals that use SONAR are whales, dolphins, rats and bats. When
bats use SONAR it is called echolocation.

Listen Safely and More About Sound
1. How do loud sounds damage your hearing? Can your hearing get better after
this damage? Why or Why not?
Loud sounds damage your hearing by killing the hair cells in your ears. After
the damage is done, the hair cells can never get better, but hearing aids
make the sounds seem louder so you can hear better.
2. Why does sound travel through solids faster than through gasses?
Sound travels through solids faster than through gasses because the
molecules in solids are packed closer together. The closer the molecules,
the faster the sound waves travel from one molecule to the next. For
example, sound travels 770 miles per hour through air, yet it travels 11,630
mph through steel.
3. How does ear wax help your ears?
Ear wax helps keep your ears clean. As wax forms inside the ear canal, it
clings to dirt particles. Eventually the wax works its way out of the ear,
caring the dirt along with it.
4. List 3 sounds and tell what their normal decibel level is.
whisper is 20 dB
normal talking 60 dB
jet 120 dB
firecracker exploding 140
