5th Grade Topic 1 Question
If
Mrs. B was plucking a string on her
guitar and she wanted to create a
higher pitch sound, what would she
need to do to the string?
5th Grade Topic 1 Answer
Mrs.
B would need to tighten the
string on the guitar by turning the
tuning key. Once Mrs. B tightened the
string, the string would create a
higher pitch.

Define
wavelength. How do we
measure it?
5th Grade Topic 2 Answer
Wavelength
measures the actual length of
a wave. We measure wavelength by looking
at the distance from either crest to crest
or trough to trough.

How
does sound travel? Describe
where sound starts and how it travels
to its ending point.
4th Grade Topic 4 Answer
Sound
starts at a sound source, and
travels though a medium (solid, liquid,
or gas) and into our ear. The sound
then bounces off of our eardrum, and
then the nerves in our ear transport
the sound to our brain, which then
Return
processes the sound.

is sound made?
3rd Grade Topic 5 Answer
Sound
is made when an object or
material vibrates.

can determine a sound waves amplitude
by looking at the height of the wave. The
higher the amplitude, the louder the sound,

2nd Grade Topic 7 Question
If
Daniel had a thin rubber band and
Emma had a thick rubber band and
both of them plucked their rubber
bands, what would the difference be
in sound?
2nd Grade Topic 7 Answer
Daniel’s
thin rubber band would
create a higher pitched sound.
(Faster vibrations.)
Emma’s
thicker rubber band would
create a lower pitched sound. (Slower
vibrations.)

Where
are the crest and the trough
located on a wave?
2nd Grade Topic 8 Answer
The
crests are located at the high
points of a wave, and the troughs are
located at the low points of the wave.

1st Grade Topic 9 Question
What
is pitch?
1st Grade Topic 9 Answer
Pitch
is how high or low a sound is. A
flute would be an example of an
instrument that creates a high pitch
sound, and a tuba would be an example
of an instrument that creates a low
pitch sound.

1st Grade Topic 10 Question
What
is frequency? How do you
create high frequency? How do you
create low frequency?
1st Grade Topic 10 Answer
Frequency
is the speed at which something
vibrates (or the number of vibrations per
unit of time).
 To
create a high frequency, one would need fast
vibrations (and we would see many crests and
troughs).
 To create a low frequency, one would need slow
vibrations (and we would see fewer crests and
Return
troughs).

Explain
the difference between pitch
and volume. Support your explanation
by giving examples!
1,000,000 Answer
Pitch
is how high or low a sound is. Volume is how
loud or soft a sound is. Some high pitch sounds can
both be loud and soft. For example, both a kittens’
meow and a fire trucks’ siren have high pitches, but
a kitten projects a soft volume, while a fire truck
projects a loud volume. The same goes for sounds
that have low pitches, too!
