The first picture shows a baby crying. The second picture shows

a woman whispering. How would you describe each sound?

Some ways you could describe the baby crying include loud volume and high pitch.

Some ways you could describe the woman whispering include low volume and low pitch.

Waves transmit energy from one

place to another. Sound is produced

as these waves cause vibrations as

they travel through matter.

How are sounds created
when you play a drum?

When you tap a drum with
your hand or a stick, it causes
the drumhead to vibrate. The
vibrations produce sound.

Objects vibrating rapidly have a higher pitch than objects vibrating

more slowly.

In which scenario is the guitar played with a higher pitch?

Scenario A:

Scenario B:

Marley has had the same
strings on her guitar for a
few weeks, so they are

loose. When playing in the
talent show, she strums her

guitar strings gently.

Josh put new strings on his

guitar before the talent

show and tightened them.
When playing in the talent
show, he strums his guitar
strings as hard as he can.

Marley's guitar has a lower pitch than Josh's guitar. Marley's loose
strings and gentle strumming cause the strings to vibrate slowly,
producing a low pitch. Josh's tight strings and hard strumming

cause the strings to vibrate quickly, producing a high pitch.

Sound travels through different mediums at different speeds.
Which of the following will sound travel through the fastest?

(open field, brick wall, water)

Sound travels in waves called compression waves. Compression waves must have a medium to
travel through. Sound travels fastest through solids because the particles are packed together.

Sound travels slowest through gases because the particles are farther apart.

produce sounds in different ways such as strumming, tapping,
and blowing. Identify how each instrument produces sounds.
