What is a
pitch?
How high or
low a sound
is
What is a
wave length?
The distance from a
point on one wave, to
the same point on
another wave
What is a
frequency?
When you measure the
number of waves that
pass in a second
What is
reflection?
A wave’s
bouncing off
a surface
What is
absorption?
It stops sound waves
from reflecting or
traveling any
farther
What is
transmission?
When sound waves
keep moving
through materials to
produce sound
What is a material
that allows
electricity to
travel through it
easily?
conductor

When riding in a car, you
notice that the wheels
make sounds against the
pavement. The pitch rises
as the car speeds up. State
a hypothesis based on this
observation.
The pitch of the wheels
increases with speed
because the vibrations
caused by the wheels get
faster as the car moves
faster.
You want to experiment to
test how well various
materials muffle sounds.
Which variables would you
keep the same and which
would you change?
Same: person
listening, sound
being blocked, room
where test is made.
Change: material
blocking sounds.
What instrument
plays
at a higher pitch,
a bass or a violin?
A violin
Olivia is standing at her
front door. Her friend
Gabe is five houses down
the street. Olivia yells,
“Gabe!” How is the
sound of Olivia’s voice
transmitted to Gabe?
The sound is
transmitted by the
vibrations of air
molecules between
Olivia and Gabe.
Gabe doesn’t hear Olivia
when she calls. When
she calls again, what are
two things she can do to
make sure that Gabe
hears her?
Move closer so that the
sound doesn’t have to
travel so far and yell
louder by cupping her
hands around her mouth to
direct the sound waves in
Gabe’s direction.
