Stretch the rubber bands
around the containers and
pluck them to hear
sounds.
Metal coat hangers with a
string tied on the opposite
sides of the bottom. Hold
the strings and bang the
hangers into tables,
chairs, etc. and listen to
the sound. Next, wrap
each string around a
finger, stick the fingers in
your ears and repeat
banging the hanger onto
assorted surfaces. The
sound will be greatly
magnified.
thrown away
to their mouth and talks, stretch the
string taunt for best transmission.
Assorted sizes of caruga tubeswhirl them around in the air to
produce sound
Assorted sizes of PCV pipe to
thump. If smaller pipes are inserted
into a larger pipe, the pitch can be
modulated by sliding the smaller
pipe back and forth while thumping
the whole apparatus.
Safety caution: Make sure that
adequate space is available for

Optional task cards for students.
Can you make sounds with the
materials provided? Record on a Tchart what you used and how you
made the sound.
Gather four items that make sound
and rank them on a flow chart; label
your ranking method.
What if you could not hear as well
as everybody else? Put ear plugs in
your ears and repeat one of the
activities. How was your experience
different or the same? Record your
findings on a Venn diagram.
How many ways can you
change the sounds that
objects make? Record what
you did and how the sound
was different.
Get a timer, what can you do
to make the sound louder?
Softer? Compare your results
to someone else's and make
a comparison chart.
What sounds can you hear
inside of your body? Does
everyone's body make the
same sounds? Make a table
to show what you found out.
Does sound travel better
through air, water, or solids?
Prove what you think and
write a persuasive
summary.
Do rubber bands make the
same sound? Prove what
you think. Find supporting
evidence in a book.
How do caruga tubes make
sound? Draw a diagram to
show your thinking.
